Low Distortion Lens – S12012003020F

S12012003020F-Manual Focus Fixed Aperture Low Distortion M12 Mount 1/2″ 8MP CCTV Lens with 38° Diagonal FOV, F2.0, and IR Correction.

12mm 8MP M12 Low Distortion Machine Vision Lens

This 12mm 8MP M12 low distortion lens is designed for compact machine vision and industrial imaging systems that require detailed image capture and controlled geometric reproduction. With a 1/2″ image format, <1.8% distortion, F2.0 aperture, and 8G optical structure, it provides a practical combination of resolution, optical stability, and compact integration.

The M12x0.5 mount and 25.1mm TTL make this lens suitable for embedded cameras and space-constrained vision equipment. Explore TOWIN’s M12 Lenses for additional compact optical solutions.

Product Core Highlights

• 8MP high-resolution imaging: Supports detailed image capture for compact industrial and machine vision cameras.
• <1.8% low distortion: Helps preserve object geometry and maintain consistent image reproduction across the field of view.
• 12mm fixed focal length: Provides a controlled 38° diagonal FOV for targeted inspection and observation.
• 8G optical structure: A multi-element optical configuration designed to support high-resolution imaging performance.
• Compact M12x0.5 interface: Well suited to embedded cameras and vision systems where installation space is limited.

M12 Low Distortion Lens Applications

The 12mm focal length and 38° diagonal field of view make this lens suitable for applications requiring a defined viewing area rather than ultra-wide scene coverage. Its <1.8% distortion performance is especially valuable when the captured image needs to retain the relative shape and position of inspected objects.

Designed for compact machine vision inspection applications, this lens can be used for component inspection, part presence detection, surface inspection, and positioning tasks. The 8MP resolution provides sufficient image detail for identifying features on manufactured components, while the low distortion design helps maintain consistent object geometry.

For automated assembly and production-line vision, the lens can monitor a specific work zone such as a fixture, conveyor section, or assembly station. The 0.15m M.O.D. allows relatively close installation when the camera needs to be positioned near the inspection target.

The lens is also suitable for embedded AI vision systems where a compact M12 interface is required but the camera still needs high-resolution image capture. Manual focus enables optical adjustment during system integration based on the actual working distance.

Typical compatible devices and systems include:

• 8MP machine vision cameras
• Compact industrial cameras
• Embedded AI vision cameras
• Automated optical inspection systems
• Component inspection cameras
• Part positioning systems
• Conveyor inspection cameras
• Robotic inspection cameras
• Assembly-line vision systems
• Compact industrial imaging devices

For broader automated inspection requirements, TOWIN’s Machine Vision solutions provide additional optical configurations for different sensors, working distances, and fields of view.

Frequently Asked Questions

Q: What type of lens is this 12mm M12 lens?
A: It is an 8MP M12 fixed focal lens designed for compact machine vision and industrial imaging systems, with <1.8% distortion and a 1/2″ image format.

Q: Is this considered a low distortion lens?
A: Yes. The specified distortion is below 1.8%, making it suitable for applications where maintaining object shape and geometric consistency is important.

Q: What is the field of view of the 12mm lens?
A: The lens provides a 38° diagonal, 30° horizontal, and 23° vertical field of view.

Q: What sensor size is this lens designed for?
A: It is designed for a 1/2″ image format and is suitable for compact 8MP imaging systems using a compatible sensor and M12 interface.

Q: Is the focus adjustable?
A: Yes. The lens uses manual focus, allowing engineers to optimize image sharpness according to the actual installation distance.

Q: What does the 8G+IRCF structure mean?
A: 8G indicates an eight-element optical structure, while IRCF refers to an infrared cut filter. IRCF should not be interpreted as an optically IR-corrected lens.

Q: Is this lens suitable for machine vision?
A: Yes. Its 8MP resolution, <1.8% distortion, 12mm focal length, F2.0 aperture, and M12x0.5 mount make it suitable for compact machine vision and industrial imaging applications.

Q: Can this M12 lens be customized?
A: TOWIN can support OEM and ODM optical projects based on requirements such as sensor format, focal length, field of view, working distance, mounting interface, and mechanical dimensions.

Lens Selection Resources

Selecting the right machine vision lens requires matching the focal length and field of view to the sensor, working distance, required resolution, and acceptable distortion. TOWIN’s Lens Selection Guide provides useful guidance for evaluating these optical parameters.

You can also use the FOV Calculator when estimating the field of view required for a particular camera and inspection distance.
