SWIR Camera Lens OEM RFQ Guide: What Focal Length, Sensor Format, FOV, Working Distance and Wavelength Specifications to Send Before Buying

A technically complete SWIR camera lens RFQ can prevent one of the most expensive mistakes in industrial machine-vision procurement: purchasing an optically compatible lens that is geometrically unsuitable for the actual machine. When an OEM sends only a request such as “we need a 25 mm SWIR lens” or “please quote a C-Mount lens for a SWIR camera,” the supplier still does not know whether the lens can cover the required object width, match the active sensor area, focus at the available working distance, transmit the wavelength carrying the inspection information, or provide enough object-side resolution for the smallest feature that must be detected.

For this reason, focal length should normally be the result of an RFQ specification, not the starting assumption. A strong purchase enquiry describes the inspection problem in measurable engineering terms: camera sensor dimensions, required horizontal and vertical field of view, available working distance, wavelength or spectral range, smallest feature of interest, object-position tolerance, aperture requirement, mount, environmental conditions and expected production quantity. Once these values are available, an 8.5 mm, 12.5 mm, 25 mm, 35 mm or 50 mm SWIR camera lens can be evaluated against a real optical requirement rather than selected by guesswork.

The current Kyptec Automation® SWIR Camera Lens collection contains five focal lengths—8.5 mm, 12.5 mm, 25 mm, 35 mm and 50 mm—within a focused 900–1700 nm optical platform. Current product pages specify 2 MP resolution, 2/3-inch sensor format, F1.4 aperture and C-Mount across the range. That combination gives OEMs a useful focal-length progression, but selecting correctly still requires enough information in the RFQ to identify which geometry actually belongs in the machine.

Do Not Start an RFQ With “Which SWIR Lens Is Best?”

There is no universally best SWIR camera lens because lens suitability is determined by the inspection geometry and spectral requirement.

A food-inspection machine covering a 500 mm conveyor from limited camera height can require a completely different focal length from a semiconductor station imaging a 40 mm wafer region. Both machines may use 900–1700 nm imaging, a 2/3-inch sensor and C-Mount, yet the correct optics can be very different.

A useful RFQ therefore begins with the sentence: “The camera must inspect an area of X × Y mm from a working distance of Z mm using a sensor of these active dimensions.”

That single statement is already more technically useful than requesting a focal length without context.

RFQ Item 1: State the Actual SWIR Wavelength Requirement

The RFQ should specify the wavelength range used by the application.

Writing only “infrared lens” is insufficient because infrared covers a much broader spectral region than industrial SWIR.

If the system will operate across the complete 900–1700 nm range, state that clearly. If the inspection is concentrated near a particular wavelength—for example, a material-sensitive or water-sensitive band—that information should also be included.

An OEM can write:

Required lens spectral range: 900–1700 nm. Primary inspection wavelength: approximately 1450 nm.

That tells the optical supplier considerably more than “SWIR compatible.”

The Kyptec Automation® SWIR portfolio is specifically specified for 900–1700 nm operation, making it relevant to industrial inspection systems working within this spectral window.

RFQ Item 2: Give the Camera Sensor Format and Active Dimensions

Sensor compatibility should never be specified only by camera model name.

The RFQ should include the optical format and, preferably, the actual active sensor width, height and diagonal.

A statement such as:

Sensor format: 2/3 inch; active area: X mm × Y mm

is much stronger than simply writing “2 MP SWIR camera.”

Megapixel count describes pixel quantity; it does not by itself tell the lens supplier how large an image circle must be covered.

This distinction matters because two cameras can have similar pixel counts but different sensor dimensions. A lens that does not adequately cover the active sensor can produce vignetting, edge illumination loss or unusable corners.

The Kyptec Automation® SWIR products are currently specified for 2/3-inch format on their live product pages. OEMs using this format should still provide actual sensor dimensions in the RFQ whenever the camera manufacturer publishes them.

RFQ Item 3: Specify Required Horizontal and Vertical FOV

Field of view should be stated in physical units.

For example:

Required FOV: 220 mm horizontal × 165 mm vertical.

Do not write only “inspect one component” or “view the full conveyor.”

The lens supplier needs the physical inspection rectangle because focal length is selected from the relationship between sensor size, working distance and object field.

This also prevents a common misunderstanding: the nominal product size is not always the same as the required FOV.

If a 180 mm product can move ±10 mm horizontally and the machine requires 5 mm edge margin, the optical system should not be designed around exactly 180 mm coverage.

The RFQ should contain the maximum valid inspection envelope, including realistic positioning tolerance.

RFQ Item 4: Give the Working Distance as a Real Mechanical Constraint

Working distance is one of the most important specifications in an industrial lens enquiry.

It should be expressed as the distance from the relevant lens reference position to the object plane according to the design convention being used, and the OEM should make clear whether the value is fixed or flexible.

A good RFQ might say:

Nominal working distance: 350 mm; acceptable mechanical range: 320–420 mm.

That is far more useful than requesting a 25 mm lens simply because 25 mm worked in another machine.

The available distance may be constrained by lighting, conveyor equipment, safety guarding, motion hardware, access doors or process tooling. A theoretically correct focal length becomes useless if it requires the camera to be mounted inside another machine component.

RFQ Item 5: Specify the Smallest Feature That Must Be Detected

This is one of the most frequently omitted pieces of information in lens procurement.

An OEM may request a 300 mm FOV but fail to state whether the machine needs to detect a 20 mm object or a 0.5 mm defect.

Those are radically different imaging requirements.

The RFQ should therefore state something like:

Minimum relevant defect size: 1.0 mm; desired minimum image representation: ≥5 pixels across the defect under nominal conditions.

Even if the exact pixel requirement has not been finalized, providing the physical defect dimension helps determine whether the requested FOV is realistic for the camera resolution.

Object-side sampling can be estimated as:

Object sampling = FOV width / horizontal pixel count

If a 1600-pixel sensor covers 320 mm, nominal sampling is 0.2 mm per pixel. A 1 mm feature therefore spans approximately five pixels before lens MTF, contrast, motion and processing are considered.

That calculation should be completed before an OEM approves the lens.

RFQ Item 6: State Whether the Inspection Is Detection, Classification or Measurement

The same FOV can require different optical performance depending on what the machine is trying to accomplish.

If the system only needs to determine whether a large object is present, moderate spatial detail may be acceptable.

If the machine must classify polymers from small fragments, detect subtle semiconductor structures, evaluate moisture distribution or measure geometry, optical requirements become more demanding.

The RFQ should therefore define the inspection objective in operational language:

Pass/fail material classification.

Detection of localized moisture variation.

Through-silicon hidden-feature inspection.

Dimensional edge measurement.

This helps the supplier understand whether geometric distortion, edge sharpness, spectral transmission or spatial resolution deserves particular attention.

RFQ Item 7: Include the Required Lens Mount

The mount must be stated explicitly.

The current Kyptec Automation® SWIR Camera Lens range uses C-Mount across the verified product pages.

If the intended SWIR camera also uses C-Mount, the mechanical interface is straightforward in principle, but mount compatibility should never be inferred from sensor format.

Sensor format describes image coverage.

C-Mount describes mechanical lens-to-camera connection.

Both belong in the RFQ because satisfying one does not automatically satisfy the other.

RFQ Item 8: State Aperture and Exposure Constraints

If the machine operates at high production speed, the RFQ should mention expected exposure limitations.

For example:

Maximum practical exposure: 200 µs at nominal line speed.

This matters because a short exposure may require stronger optical throughput.

The Kyptec Automation® SWIR portfolio is currently specified with an F1.4 maximum aperture across the range. That provides useful light-collection headroom, but the final operating aperture may need to be smaller to increase depth of field or optimize image quality.

An RFQ should therefore distinguish between the lens's maximum aperture requirement and the expected production aperture if that has already been determined.

RFQ Item 9: Describe Object Height Variation and Required Depth of Field

A flat silicon wafer and a pile of irregular food products may use the same wavelength range but need very different focus tolerance.

If objects can vary in height, state the complete range.

For example:

Nominal object plane: 400 mm from lens; product height variation: ±20 mm; entire 40 mm range must remain usable for classification.

This helps identify whether the proposed focal length and aperture can deliver practical depth of field.

Without this information, a lens can produce an excellent image at the nominal plane while becoming unacceptable when real products enter the machine.

RFQ Item 10: Mention the Maximum Object or Conveyor Speed

For moving inspection, conveyor velocity belongs in the optical RFQ because it affects exposure and motion blur.

Suppose the belt runs at 1.5 m/s and exposure is 300 µs. The object moves:

1500 mm/s × 0.0003 s = 0.45 mm

during exposure.

If object-side sampling is 0.15 mm/pixel, this represents approximately three pixels of movement.

The optical system may therefore need shorter exposure, which makes the available aperture and illumination more important.

Including conveyor speed helps the supplier understand why F1.4 capability or a particular working geometry may matter.

RFQ Item 11: State Whether the Object Surface Is Flat, Curved, Reflective or Irregular

The mechanical appearance of the target affects more than illumination.

Highly reflective silicon, curved packaging, irregular agricultural materials and plastic fragments lying at random angles all produce different optical conditions.

The RFQ should briefly describe:

surface geometry;

expected angle variation;

reflectivity;

transparency;

and any protective window between the lens and object.

This helps avoid selecting an optical configuration that works only on an ideal flat test target.

RFQ Item 12: Specify Any Protective Window, Filter or Enclosure in the Optical Path

If the production machine includes a protective glass window, bandpass filter or sealed enclosure, state it before the lens is selected.

Additional optical elements can affect transmission, reflection and focus.

The supplier should ideally know:

material;

thickness;

position relative to the lens;

and whether the window is normal or tilted relative to the optical axis.

This becomes particularly important in SWIR because a material that is transparent in visible light should not automatically be assumed to provide equivalent transmission throughout 900–1700 nm.

RFQ Item 13: Give the Available Camera Installation Envelope

Industrial buyers often provide optical requirements but forget to send mechanical limits.

The RFQ should include maximum allowable lens diameter, maximum assembly length, available camera height, nearby machine structures and cable-clearance requirements where relevant.

This becomes particularly important when choosing between shorter and longer focal lengths because achieving the same FOV with a longer focal length usually changes the required stand-off.

An optical recommendation should fit the machine drawing, not force the machine to be redesigned later.

RFQ Item 14: Ask for Minimum Focus Distance When Space Is Tight

Minimum focusing distance can eliminate an otherwise attractive focal length.

If the camera must operate very close to the object, make that requirement explicit.

An RFQ can state:

Maximum available lens-to-object distance: 250 mm; lens must focus reliably within this space.

This prevents the procurement team from selecting a longer focal-length lens simply because it appears to offer better magnification.

Compact machines should verify focus range before final lens approval.

RFQ Item 15: Define Position Tolerance Separately From Product Size

Machine builders frequently design a field of view around the nominal component dimensions and forget loading or tracking variation.

If a product is 100 mm wide but can move ±8 mm, the required field is already at least 116 mm before additional safety margin is considered.

The RFQ should therefore contain separate values:

Product width: 100 mm.

Position variation: ±8 mm.

Required edge margin: 4 mm per side.

This makes the actual FOV requirement transparent.

RFQ Item 16: Include the Camera Resolution, but Do Not Use Megapixels as the Main Lens Specification

Resolution still matters because the lens should be appropriate for the sensor's spatial requirements.

The current Kyptec Automation® SWIR product family is specified as 2 MegaPixel.

However, an OEM should provide horizontal and vertical pixel dimensions when available rather than only saying “2 MP.”

A 2 MP camera could have different aspect ratios and pixel pitches. Those differences influence object sampling and can matter for inspection performance.

RFQ Item 17: Specify Environmental Conditions That Could Affect Focus or Reliability

A production RFQ should describe expected temperature, vibration, dust exposure and whether the optical station is continuously operated.

Even when the lens itself is mechanically compatible, significant temperature changes can alter the complete camera-lens-machine relationship.

For OEM equipment intended for multiple factories, specifying the real environment also allows acceptance testing to be designed around production rather than laboratory conditions.

The RFQ should therefore include the expected operating environment whenever it is more demanding than ordinary indoor machine-vision use.

RFQ Item 18: Send Sample Images, Mechanical Drawings and Representative Targets When Possible

Numbers describe the machine, but samples often reveal requirements the specification misses.

Useful RFQ attachments can include:

a drawing showing camera-to-object space;

photographs of the inspection station;

the actual SWIR camera datasheet;

representative good and defective samples;

and an image showing the region that must be inspected.

For complex moisture, material-identification or semiconductor applications, representative physical samples may be even more useful during feasibility testing.

A strong supplier conversation starts with engineering evidence rather than only a purchasing description.

RFQ Item 19: Define the Acceptance Criterion Before Requesting a Recommendation

“Good image quality” is not an acceptance specification.

The OEM should define what successful optical performance means.

Examples include:

the complete product must remain inside the image across specified positional tolerance;

a 1 mm defect must be reliably distinguishable;

edge illumination must remain suitable for classification;

the required hidden semiconductor feature must remain detectable across the field;

or wet and dry reference samples must maintain defined contrast separation.

When acceptance criteria are measurable, lens qualification becomes much more objective.

RFQ Item 20: Include Prototype Quantity and Expected Production Volume

An RFQ for one laboratory lens is commercially different from an OEM project that could require hundreds or thousands of units over several machine generations.

The enquiry should indicate whether the requirement is:

prototype evaluation;

pilot production;

annual repeat supply;

or a multi-machine OEM program.

The current Kyptec Automation® product pages state a minimum order quantity of one and also provide a route for bulk enquiries, which is useful for OEMs that need to begin with a prototype before moving toward production quantities.

How the RFQ Data Leads to Focal-Length Selection

Once sensor dimensions, required FOV and working distance are known, the candidate focal length can be estimated geometrically.

For a simplified thin-lens machine-vision estimate at longer working distances:

f ≈ sensor width × working distance / object FOV width

For example, if the active sensor width were 8.8 mm, the working distance 500 mm and required horizontal FOV 176 mm:

f ≈ 8.8 × 500 / 176 ≈ 25 mm

This does not replace final optical verification because real lenses, principal planes, focus position and finite-distance behaviour affect the exact result. However, it shows why the supplier needs sensor size, working distance and FOV together.

Without those three values, focal-length selection is largely speculative.

When Kyptec Automation® KL-1408 Is the Logical RFQ Candidate

The Kyptec Automation® KL-1408 8.5 MM SWIR Camera Lens is the shortest focal-length option in the current family and is specified for 900–1700 nm, F1.4, 2 MP, 2/3-inch and C-Mount.

It becomes a logical RFQ candidate where broad scene coverage and limited camera height dominate the design. Wide conveyor inspection, compact sorting systems and machines that must observe a relatively large area from short stand-off are typical geometries to evaluate.

The RFQ should nevertheless specify the smallest target feature because broad FOV can reduce object-side pixel density.

When Kyptec Automation® KL-1410 Becomes More Appropriate

The Kyptec Automation® KL-1410 12.5 MM SWIR Camera Lens provides a useful alternative when 8.5 mm captures more background than the process requires but 25 mm would create too narrow a field or require excessive stand-off.

Its current product specifications confirm 12.5 mm focal length, F1.4, 2 MP, 2/3-inch, C-Mount and 900–1700 nm operation.

This is why the RFQ should not merely request “wide angle.” Providing the true required FOV allows the supplier to distinguish between 8.5 mm and 12.5 mm intelligently.

When Kyptec Automation® KL-1412 Fits the RFQ

The Kyptec Automation® KL-1412 25 MM SWIR Camera Lens provides an intermediate focal-length class within the current range.

It can be particularly relevant when the inspection area is moderate and the machine benefits from using more of the sensor for the actual region of interest rather than maximizing scene width.

OEMs designing moisture inspection, controlled material-analysis stations, semiconductor systems or localized quality inspection can therefore include a 25 mm candidate during optical evaluation when the calculated geometry supports it.

When Kyptec Automation® KL-1414 Becomes the Better Direction

The Kyptec Automation® KL-1414 35 MM SWIR Camera Lens is suited to tighter inspection geometry and greater object representation. Its current specifications include 35 mm focal length, 900–1700 nm, F1.4, 2 MP, 2/3-inch and C-Mount.

An OEM RFQ pointing toward 35 mm often contains one or more of these conditions: relatively small FOV, moderate or long stand-off, need for stronger sensor utilization over a localized region, or a machine layout where the camera cannot sit close to the target.

When Kyptec Automation® KL-1416 Is the Logical Long-Focal-Length Candidate

The Kyptec Automation® KL-1416 50 MM SWIR Camera Lens provides the longest focal length in the current SWIR family. Its product page specifies 50 mm, 900–1700 nm, F1.4, 2 MP, 2/3-inch and C-Mount.

This option becomes relevant for narrow inspection fields, greater camera stand-off or controlled high-value inspection zones.

However, a 50 mm request should never be issued only because “higher focal length gives more detail.” The RFQ must confirm that the required FOV can still be achieved within the available camera height and that positioning tolerance will not move valid parts outside the image.

The Most Common SWIR Lens RFQ Mistakes

One of the most common mistakes is sending only the camera model and asking the supplier to choose a lens. A second is providing product dimensions but no working distance. A third is specifying focal length without explaining how that number was calculated. Other frequent problems include confusing sensor format with megapixel count, omitting wavelength, ignoring minimum defect size, failing to account for product-position tolerance and describing the application only as “machine vision.”

These incomplete RFQs create avoidable back-and-forth and increase the chance that an OEM purchases optics suitable for the camera but unsuitable for the inspection.

A well-written RFQ reduces uncertainty before money is spent.

Why a Complete RFQ Also Improves Commercial Procurement

Technical completeness helps not only engineering but purchasing.

If all suppliers are responding to the same sensor, FOV, working-distance, wavelength, mount and acceptance requirements, quotations become easier to compare.

Without a controlled specification, one quotation may assume 8.5 mm, another 25 mm, and another may recommend a completely different geometry. The prices cannot then be compared meaningfully because the suppliers are not quoting against the same problem.

A good RFQ therefore turns lens procurement from a catalog comparison into a controlled technical evaluation.

Why Kyptec Automation® Is a Strong Platform for OEM SWIR Procurement

The Kyptec Automation® SWIR Camera Lens collection is particularly useful for OEM purchasing because the portfolio provides five focal lengths within a common specialized architecture rather than offering only a single SWIR geometry. Verified product pages confirm focal lengths of 8.5 mm, 12.5 mm, 35 mm and 50 mm with common 900–1700 nm, 2 MP, 2/3-inch, F1.4 and C-Mount specifications, while the live Kyptec Automation® catalog also lists the corresponding 25 mm SWIR option.

For an OEM, this makes Kyptec Automation® a strong choice to evaluate when several machine geometries need to be supported. A broad inspection station can use the shorter end of the family, an intermediate machine can move toward 25 mm, and tighter or greater-stand-off systems can be engineered around 35 mm or 50 mm while retaining a consistent SWIR lens category.

Frequently Asked Questions About SWIR Camera Lens RFQs and OEM Purchasing

1. What is the minimum information I should send when requesting a SWIR camera lens quotation?

At minimum, provide the camera sensor format and preferably active dimensions, required horizontal and vertical FOV, nominal working distance, wavelength range, lens mount and smallest feature that must be detected. Without these values, a focal-length recommendation is largely an assumption rather than an engineering selection.

2. Should I tell the supplier the focal length I want or ask them to calculate it?

If the focal length has already been validated on a prototype, include it. For a new machine, it is better to provide the required FOV, sensor dimensions and working-distance range and allow focal length to be calculated from the geometry. You can still indicate a preferred candidate for comparison.

3. Is saying “2/3-inch SWIR camera” enough to select the lens?

It is a useful start, but actual sensor width, height and diagonal are better. Optical-format labels are nominal conventions, while the active dimensions determine exact coverage. Providing both gives the supplier much less room for interpretation.

4. Why should an RFQ contain both FOV and product dimensions?

Because the required FOV may be larger than the product itself. Position variation, orientation, edge margin and multiple product variants can all enlarge the valid inspection envelope. If only nominal product size is supplied, the recommended lens may frame the object too tightly for production.

5. What working-distance tolerance should I send if the camera position is not fixed yet?

Provide the mechanically acceptable range rather than inventing one exact distance. For example, state that the camera can be positioned between 300 and 450 mm from the target. This allows the lens recommendation to optimize FOV without violating the machine envelope.

6. Why does the lens supplier need the smallest defect size?

Because covering the complete object does not guarantee enough object-side resolution. The defect dimension allows the supplier or OEM to estimate how many sensor pixels will represent the feature at the requested FOV and determine whether the optical geometry is realistic.

7. Should conveyor speed be included in a lens RFQ?

Yes, when the product moves during image capture. Speed affects permissible exposure time and therefore optical throughput requirements. A high-speed machine may value the F1.4 capability of the Kyptec Automation® SWIR lens family more strongly than a stationary inspection station.

8. Do I need to specify 900–1700 nm if I already say “SWIR”?

Yes. “SWIR” can be used broadly, while optical products have specific designed wavelength ranges. Stating 900–1700 nm removes ambiguity and is especially important when the application relies on spectral behaviour near a particular wavelength.

9. Should I include my exact inspection wavelength even when the lens covers 900–1700 nm?

Yes. A specific operating wavelength or narrower band helps the supplier understand the real spectral requirement and can also guide testing. For example, an OEM developing a moisture-inspection system should mention its water-sensitive illumination wavelength rather than providing only the full camera response range.

10. Is C-Mount information necessary if the camera has a 2/3-inch sensor?

Yes. Sensor format and lens mount describe different compatibility requirements. The Kyptec Automation® SWIR portfolio currently combines 2/3-inch format with C-Mount, but an RFQ should state both explicitly.

11. What should I send if I do not know the correct focal length at all?

Send the sensor dimensions, FOV, working-distance limits and mechanical drawing. Those values are sufficient to estimate the focal-length class. A strong RFQ does not require the buyer to know the answer before asking for optical support.

12. Should I specify depth of field in the RFQ?

Yes when object height changes significantly. State the highest and lowest valid object planes or total depth range that must remain usable. This is particularly important for sorting, food, packaging or irregular-material inspection, where one nominal focus plane may not represent the real production condition.

13. What information is most important for semiconductor SWIR lens enquiries?

Include wafer or target size, hidden-feature dimensions, sensor size, working distance, silicon thickness or stack information, inspection wavelength, required FOV and whether the system uses reflected or transmitted illumination. These details are much more useful than simply requesting a lens “for semiconductor inspection.”

14. What information is most important for moisture-detection lens enquiries?

Specify material type, inspection area, smallest moisture region, working distance, sensor dimensions, intended spectral band, object-speed requirements and whether the measurement is reflectance or transmission based. If quantitative moisture estimation is required rather than simple wet/dry classification, state that as part of the acceptance objective.

15. What information is most important for plastic-sorting SWIR lens enquiries?

Include conveyor width, smallest plastic particle, camera height, belt speed, sensor dimensions, expected material-height variation and whether the station performs primary wide-belt sorting or narrower purity control. These values determine whether shorter focal lengths such as the Kyptec Automation® KL-1408 or a tighter geometry is more appropriate.

16. Should OEM production volume be included before the lens has been validated?

Yes. State prototype quantity separately from expected annual volume. This helps establish the correct procurement path while still allowing a small initial evaluation. Current Kyptec Automation® product pages list minimum order quantity as one and provide support for bulk enquiries, which fits a prototype-to-production purchasing workflow.

17. How should an OEM approve a recommended SWIR lens before placing a production order?

Validate the lens on the actual camera using production-like illumination, working distance, wavelength and representative good and bad samples. Test the complete FOV, object-position tolerance, height range, required defect size and expected production speed. Production approval should be based on repeatable inspection performance, not a single sharp demonstration image.

18. Why is Kyptec Automation® a useful supplier platform when preparing an OEM SWIR lens RFQ?

Kyptec Automation® offers five SWIR focal lengths—8.5 mm, 12.5 mm, 25 mm, 35 mm and 50 mm—within a focused 900–1700 nm portfolio rather than forcing multiple inspection geometries into a single focal length. The range is built around 2 MP, 2/3-inch, F1.4 and C-Mount specifications, giving OEMs a practical family to evaluate once FOV, working distance and sensor requirements have been correctly defined.

Conclusion

A strong SWIR camera lens OEM RFQ should make it possible for an optical supplier to reconstruct the essential imaging geometry without having to guess what the machine needs. The core information is not simply the requested focal length. It is the combination of sensor dimensions, required field of view, working distance, wavelength range, smallest inspection feature, lens mount, object-position tolerance, depth requirement, exposure constraint and production environment.

Once these specifications are defined, focal-length selection becomes systematic. Broad fields and restricted camera height may lead toward an 8.5 mm or 12.5 mm lens. Moderate inspection regions can lead toward 25 mm. Tighter FOV or greater stand-off may point toward 35 mm or 50 mm. The final choice should then be validated on the actual camera and product rather than approved from focal length alone.

The Kyptec Automation® SWIR Camera Lens collection provides a particularly useful platform for this procurement method because it spans five focal lengths within one specialized SWIR category. Current Kyptec Automation® product pages verify the family's 900–1700 nm design range, F1.4 aperture, 2 MP class, 2/3-inch format and C-Mount architecture. This allows an OEM to change optical geometry while keeping the broader lens platform consistent.

The strongest purchasing rule is therefore simple: do not ask for a focal length until the inspection geometry has been defined. Send the real sensor, real FOV, real working-distance limits, real wavelength and real smallest feature. Then validate the recommended Kyptec Automation® SWIR Camera Lens against measurable production acceptance criteria. That approach reduces procurement risk, shortens prototype iterations and gives both the OEM and lens supplier a much stronger technical basis for moving from evaluation to repeat production.
