2.1mm M12 Wide Angle Low Distortion Lens Applications

Core Application Scenes

This 2.1mm M12 low distortion lens is designed for compact camera systems that need to capture a wide scene without the strong geometric deformation commonly associated with extreme wide-angle optics. Its combination of 125° diagonal FOV and less than 1% distortion makes it particularly useful when both broad coverage and relatively accurate image geometry are required.

The ultra-short 10.5mm TTL is a key advantage for miniature camera assemblies. It allows optical integration into devices where the available space behind the lens is highly restricted, such as compact embedded vision modules, smart sensing devices, portable inspection equipment, and small robotic cameras.

For machine vision and embedded vision, the 108° horizontal FOV can cover a large working area from a short distance, while the <1% distortion specification helps reduce geometric deformation in captured images. This can be valuable for applications involving object detection, scene monitoring, spatial awareness, and computer vision analysis.

The 0.1m M.O.D. further supports close-range imaging. Instead of requiring a long working distance to obtain useful scene coverage, the lens can be positioned relatively close to the target while still maintaining a broad viewing angle.

Designed for ultra-compact wide-angle imaging, embedded vision, robotic perception, and close-range visual monitoring applications.

Frequently Asked Questions

Q: What type of lens is this 2.1mm M12 lens?
A: It is a fixed focal, wide-angle, low-distortion M12 lens designed for 1/4″ image sensors. It has a 2.1mm focal length, 2MP resolution, and M12x0.5 mount.

Q: What is the field of view of this lens?
A: With the specified OV2643 sensor, the lens provides a 125° diagonal FOV, 108° horizontal FOV, and 92° vertical FOV.

Q: How low is the distortion of this M12 lens?
A: The specified distortion is less than 1%. This makes the lens particularly suitable for wide-angle imaging systems where geometric distortion needs to be tightly controlled.

Q: Is this lens a fisheye lens?
A: No. Despite its 125° diagonal field of view, the lens is specified with less than 1% distortion. It should therefore be positioned as a wide-angle low-distortion lens rather than a fisheye lens.

Q: What sensor size is this lens designed for?
A: The lens is designed for a 1/4″ image format. The listed FOV specifications are based on the OV2643 sensor.

Q: What is the advantage of the 10.5mm TTL?
A: The 10.5mm total track length provides a very compact optical configuration. It is useful for camera modules and imaging devices where the available installation depth is limited.

Q: What applications are suitable for this 2.1mm lens?
A: Typical applications include compact embedded cameras, robotic vision modules, portable inspection equipment, edge-AI vision devices, and close-range monitoring systems requiring wide coverage with controlled distortion.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.1m, or 100mm. This allows the lens to capture objects at relatively short working distances while maintaining its wide field of view.
