8.45mm M12 6MP Low Distortion IR Corrected Lens

This 8.45mm M12 low distortion lens is designed for 1/1.8″ image sensors and 6MP industrial imaging systems, delivering a 56° diagonal field of view with distortion below -1.49%. Its IR-corrected optical design, F2.8 fixed aperture, and compact M12 × 0.5 mount make it suitable for machine vision, factory automation, and embedded industrial imaging applications requiring controlled image geometry.

When matching this lens with an industrial camera, sensor format and required field of view should be evaluated together. The Sensor Guide provides guidance on sensor compatibility, while the Lens Selection Guide can help with focal length and application selection.

Product Core Highlights

• 8.45mm fixed focal length for controlled medium-wide imaging.
• 6MP resolution for detailed industrial image capture.
• Low distortion below -1.49% for improved geometric consistency.
• IR-corrected optics for visible and near-infrared imaging systems.
• M12 × 0.5 mount with 0.2m M.O.D. for compact close-range vision applications.

This lens is part of the M12 Lenses range and provides a balance between field coverage and geometric control. Its 8.45mm focal length offers broader scene coverage than longer industrial lenses while maintaining a low-distortion optical design.

M12 Low Distortion IR Corrected Lens Applications

Core Application Scenes

This 8.45mm M12 industrial lens is designed for machine vision systems that need to capture a relatively broad inspection area while maintaining controlled geometric distortion. With a 56° diagonal and 47° horizontal FOV on a 1/1.8″ sensor, it provides useful scene coverage without moving into the extreme wide-angle range.

The lens is well suited to compact factory automation inspection systems, particularly where the camera must observe multiple components or a moderately sized work area from a limited installation distance. Its 0.2m minimum object distance also provides flexibility for close-range inspection equipment.

A key advantage is its low distortion performance below -1.49%. For machine vision applications involving edge detection, object positioning, dimensional comparison, or shape analysis, controlled distortion can help maintain more consistent geometric relationships across the captured image.

The 6MP resolution provides sufficient detail for many automated inspection tasks, while the F2.8 fixed aperture offers a stable optical configuration for systems using controlled industrial illumination. This combination makes the lens suitable for production environments where repeatable imaging is more important than adjustable photographic controls.

The IR-corrected design further extends its use into systems that employ near-infrared illumination. This can be useful in industrial inspection setups where visible and NIR imaging are used to improve material contrast, identify markings, or distinguish specific surface characteristics.

For engineers determining the required viewing coverage at a particular working distance, the FOV Calculator can be used to evaluate sensor and focal-length combinations before selecting the final lens.

Designed for low-distortion machine vision, close-range factory automation, and visible/NIR industrial imaging applications.
