8mm 8MP M12 Low Distortion Machine Vision Lens

This 8mm 8MP M12 low distortion lens is designed for high-resolution vision systems that require accurate image geometry and reliable detail reproduction. Covering a 1/1.8″ image format with less than 1% distortion, F2.2 aperture, and 58° diagonal FOV, it provides an excellent optical balance for machine vision, industrial inspection, AI vision, and compact imaging systems.

The M12×0.5 mount, fixed iris, 0.2m minimum object distance, and integrated IRCF make this fixed focal lens suitable for compact camera modules where low distortion and consistent visible-light imaging are important.

Product Core Highlights

• 1/1.8″ sensor coverage — Supports a commonly used high-resolution sensor format while providing a balanced 58° diagonal FOV.
• F2.2 fixed aperture — Provides consistent optical performance for applications operating under controlled or stable lighting conditions.
• M12×0.5 compact mount — Simplifies integration into compact machine vision and embedded camera systems.
• IRCF-equipped construction — Incorporates an infrared cut filter for visible-light imaging applications.

M12 Low Distortion Lens Applications

This 8mm M12 lens is designed for applications where low geometric distortion is more important than an extremely wide field of view. With distortion below 1%, it preserves the shape and relative position of objects across the image, making it a strong choice for vision systems that perform edge analysis, object positioning, dimensional evaluation, pattern recognition, or image-based measurement.

Designed for precision-oriented machine vision applications, the lens is well suited to automated inspection cameras, electronic component inspection, PCB inspection, packaging verification, barcode and code-reading systems, and industrial quality-control equipment. The 8MP resolution provides sufficient image detail for identifying relatively small features while the 48° horizontal FOV provides a practical working area for many close- to medium-range inspection setups.

The 0.2m minimum object distance makes the lens suitable for relatively close installation environments. This can be useful when the camera must be positioned near a production line, inspection fixture, conveyor, or individual component while still maintaining controlled image geometry.

For compact camera designs, the M12×0.5 interface provides a practical mechanical solution. This model can be compared with other M12 Lenses and TOWIN’s Low Distortion Lenses solutions when selecting optics for a new vision system.

Compatible devices and systems include:

• 8MP machine vision cameras
• Automated optical inspection cameras
• PCB inspection systems
• Electronic component inspection equipment
• Packaging inspection cameras
• Barcode and code-reading cameras
• Industrial quality-control systems
• AI-based object recognition cameras
• Compact embedded vision modules

The fixed iris provides a consistent F2.2 optical configuration, while the IRCF helps suppress unwanted infrared wavelengths for visible-light camera applications. It should be noted that IRCF refers to an infrared cut filter and does not indicate an IR-corrected optical design.

For engineers comparing sensor size, focal length, and viewing coverage, TOWIN’s Lens Selection Guide provides additional guidance. The Sensor Guide can also help with sensor-format and lens compatibility considerations.

Frequently Asked Questions

Q: What type of lens is the 8mm model?
A: It is an 8mm M12 fixed focal low distortion lens designed for 1/1.8″ sensors, providing 8MP resolution, F2.2 aperture, and less than 1% distortion.

Q: How low is the distortion of this M12 lens?
A: The specified distortion is below 1%, making this lens particularly suitable for applications where accurate image geometry and minimal edge deformation are important.

Q: Is this lens suitable for machine vision?
A: Yes. Its 8MP resolution, 1/1.8″ image format, <1% distortion, and M12 mount make it well suited to machine vision applications involving inspection, positioning, recognition, and image analysis.

Q: What is the field of view of the 8mm lens?
A: On a 1/1.8″ sensor, the lens provides a 58° diagonal, 48° horizontal, and 37° vertical field of view.

Q: Is this an IR corrected lens?
A: No. The specification “With IRCF” indicates an infrared cut filter. An IRCF helps filter infrared wavelengths for visible-light imaging, but it should not be interpreted as an IR-corrected optical design.

Q: What is the minimum object distance?
A: The minimum object distance is 0.2m, allowing the lens to be used for relatively close-range industrial inspection and imaging.

Q: What mount does this lens use?
A: The lens uses an M12×0.5 mount, which is commonly used for compact machine vision cameras, embedded vision modules, AI cameras, and other small-form-factor imaging systems.

Q: Can TOWIN customize this low distortion M12 lens?
A: Yes. TOWIN can support customized optical solutions based on sensor format, focal length, FOV, distortion, resolution, mechanical dimensions, mounting requirements, and application conditions.
