4.2mm 16MP M12 Low Distortion Lens Applications

Core Application Scenes

This 4.2mm M12 machine vision lens is developed for compact imaging systems that need to combine high resolution, broad coverage, and low geometric distortion. Its 16MP resolution allows the camera to capture fine image details, while distortion below 0.4% helps maintain the shape and relative position of objects across the image.

The 78° horizontal FOV makes the lens particularly suitable for compact inspection stations, robotic visual perception, embedded AI cameras, automated equipment monitoring, and wide-area industrial imaging. It can cover a relatively large inspection region without requiring the extreme perspective distortion normally associated with fisheye optics.

For robotic systems, the controlled distortion can be useful when cameras are used for object localization, pick-and-place guidance, workspace observation, or visual navigation. In automated inspection equipment, the combination of 16MP resolution and low distortion can support image-based measurement, defect detection, component recognition, and surface analysis where consistent image geometry is important.

The compact M12×0.5 interface and 22.20mm TTL also make this lens suitable for OEM camera modules and embedded vision devices where optical space is limited. Engineers can use Towin’s Lens Selection Guide when evaluating sensor size, focal length, FOV, and working distance requirements.

Compatible Device List

• Machine Vision Cameras: The 16MP resolution and <0.4% distortion are suitable for high-detail inspection, recognition, positioning, and measurement-oriented vision systems.
• Robotics Vision Modules: The wide horizontal FOV enables robots to observe a broad workspace while maintaining controlled image geometry.
• Embedded AI Cameras: The compact M12×0.5 form factor is suitable for edge-AI camera modules where both processing capability and mechanical space are constrained.
• Automated Inspection Equipment: High resolution helps reveal small visual features, while low distortion supports consistent imaging across the field.
• Smart Industrial Monitoring: The 90° diagonal FOV allows one compact camera to monitor a relatively broad area without using a fisheye optical design.
• OEM/ODM Camera Systems: The compact optical construction can be integrated into customized imaging devices requiring specific mechanical or optical configurations.

When designing a machine vision system, the required FOV should be evaluated together with sensor dimensions, working distance, and target size. Towin’s FOV Calculator can help engineers estimate coverage for a specific camera configuration.

For applications involving automated inspection and robotic perception, this lens can be integrated into Machine Vision and Robotics Vision systems where high-resolution image acquisition and controlled distortion are important.

Frequently Asked Questions

Q: What type of lens is the 4.2mm M12 lens?
A: It is a fixed focal, wide-angle M12 lens with a low-distortion optical design. It supports a 1/2.3″ sensor format and provides up to 16MP resolution.

Q: How low is the distortion of this lens?
A: Distortion stays below 0.4%. This ultra‑low distortion preserves accurate image geometry and minimizes deformation of straight lines and object shapes.

Q: What is the field of view of the 4.2mm lens?
A: On a 1/2.3″ sensor, the lens provides a 90° diagonal FOV, 78° horizontal FOV, and 61° vertical FOV.

Q: What resolution does this M12 lens support?
A: The specified resolution is 16MP, making it suitable for high-resolution compact vision systems where detailed image capture is required.

Q: What applications are suitable for this 16MP M12 lens?
A: Typical applications cover machine‑vision inspection, robotic vision, embedded AI cameras, automated equipment monitoring, component recognition and compact industrial imaging systems.

Q: What does the CRA specification of <14.2° mean?
A: CRA is the incident angle of chief rays hitting the sensor. A CRA under 14.2° matters for pairing with sensors requiring specific angular response or pixel design.

Q: Does the 4G2P+IRCF construction mean that this is an IR corrected lens?
A: Notably, IRCF means integrated infrared-cut filter, while IR correction stands for optical compensation across IR wavelengths. Per specs, this lens is not an IR Corrected Lens.

Q: How can I calculate whether the 4.2mm focal length is suitable for my application?
A: The required focal length depends on sensor size, working distance, target dimensions, and desired field of view. Towin’s FOV Calculator can be used to estimate image coverage, while the Focal Length Calculator can help determine a suitable focal length.
