35mm SWIR Lens: Applications & OEM Support
35mm SWIR Lens: Coverage & Working Distance
Consider the SP-SWIR3514MC when a defined inspection region needs to occupy more of the camera image. Compared with shorter focal lengths on the same sensor, 35mm generally provides a narrower field of view at the same working distance. Plan coverage and installation distance together before selecting the lens.
- Specify the inspection width and smallest relevant target feature.
- Check sensor dimensions, image-circle coverage and available mounting distance.
- Compare the actual field of view with 25mm and 50mm alternatives.
SWIR Illumination & Target Detail
Match the lens’s specified operating band to the camera response and illumination spectrum. Evaluate this 35mm C-Mount SWIR lens at the intended working distance, aperture and exposure. Include filters or protective windows in the test arrangement so the assessment reflects the complete imaging system.
- Use representative illumination wavelengths and target materials.
- Check focus, contrast and detail across the required inspection region.
- Request relevant transmission or imaging data for your acceptance criteria.
Targeted Inspection & Process Observation
Evaluate this 35mm SWIR lens for inspecting a selected conveyor region, examining material samples or observing a defined process area. Where a wider view includes unnecessary surroundings, review whether narrower coverage better matches the task while keeping the complete inspection region within the camera image.
- Describe the material, target size and required inspection result.
- Test representative samples at the intended exposure and operating speed.
- Confirm that target movement and positioning variation remain within view.
OEM Integration & Volume Supply
For OEM or distributor inquiries, identify SP-SWIR3514MC and share the camera model, sensor specifications, installation distance and housing constraints. Include sample quantity and estimated annual demand. SUPERIOR can review the proposed configuration and discuss modification feasibility before sample approval and volume-supply planning.
- Review mount compatibility, barrel clearance and focus access.
- Agree imaging and mechanical acceptance criteria for sample evaluation.
- Request a quotation covering the approved configuration, packaging and delivery needs.
Technical Reference for Camera Comparison
EMVA 1288 provides a standardized framework for presenting machine-vision camera and sensor specifications. Review the camera manufacturer’s published results when comparing sensor response and noise, then assess the 35mm lens with your actual camera, illumination and working distance.

Model: SP-SWIR3514MC
Send your camera or sensor model, illumination wavelength, working distance, required quantity and project schedule. Ask for compatibility review, sample availability and an OEM quotation.
Product & OEM Questions
Will this lens fit my camera?
Confirm the camera mount, sensor diagonal, pixel pitch and available mounting space. Send the camera model for an application review; nominal sensor format alone is not a fit guarantee.
Can I request a sample before a volume order?
Ask for current sample availability and quantity pricing. Include the lens model, required quantity and project schedule. Availability and lead time are confirmed with the quotation.
Does a nominal resolution rating guarantee my inspection result?
No. Validate the combination of lens, sensor, illumination, aperture and working distance against the required image contrast and target detail.
Can the lens or documentation be adapted for an OEM project?
Share optical targets, mechanical constraints, qualification needs and expected annual volume. Feasibility and any customization scope must be confirmed for your project.
