M12 Wide Angle Lens Core Highlights

• 2.8mm Wide-Angle Focal Length — Provides 89° diagonal, 73° horizontal, and 61° vertical field of view for broad scene coverage.
• 5MP Resolution — Designed for 5MP imaging systems where wide-angle coverage and image detail are both important.
• Controlled Optical Distortion — Distortion below -18% provides a more controlled image geometry than extreme fisheye designs.
• F2.0 Fixed Aperture — Provides a relatively bright optical configuration for compact imaging systems operating under varying lighting conditions.
• Compact M12×0.5 Mount — The standard M12 interface simplifies integration into embedded cameras and compact vision systems.
• 7G Optical Construction — The 7-element glass construction supports the optical requirements of a 5MP wide-angle imaging system.

M12 Wide Angle Lens Applications

This 2.8mm M12 lens is suitable for compact camera systems that need a relatively wide viewing angle without the extreme geometric distortion associated with fisheye lenses. Its 73° horizontal FOV provides broad scene coverage while maintaining a more controlled optical profile.

Machine Vision

The combination of 5MP resolution, 2.8mm focal length, and controlled distortion makes this lens suitable for machine vision systems where the camera needs to observe a relatively large working area.

It can be considered for inspection systems, object presence detection, positioning, classification, and other industrial imaging tasks where extreme telephoto magnification is not required.

Designed for compact machine vision inspection applications.

Embedded Vision

The M12×0.5 mount makes this lens suitable for embedded camera modules where optical dimensions and mechanical integration are important. The 25.21mm TTL provides a defined optical package for camera designers working with compact housings.

Typical applications include embedded inspection cameras, smart imaging devices, compact monitoring systems, and industrial camera modules.

Robotics Vision

A 73° horizontal field of view can provide useful scene coverage for robotic imaging systems while maintaining more controlled distortion than an ultra-wide fisheye lens. This makes the lens suitable for applications where the camera needs to observe objects or operating areas at relatively close distances.

Potential applications include robotic inspection, object detection, positioning, and compact vision modules.

See the Robotics Vision solution for more information.

Smart Security

The 2.8mm focal length and 89° diagonal FOV can provide broad coverage for compact monitoring cameras and embedded security devices. The F2.0 aperture also makes the lens suitable for applications where a relatively bright optical system is beneficial.

Wide Angle with Controlled Distortion

When selecting a wide-angle lens, field of view and distortion should be evaluated together. A shorter focal length generally provides broader scene coverage, but extreme wide-angle designs can introduce substantial geometric distortion.

With an 89° diagonal FOV and distortion below -18%, this 2.8mm lens occupies a practical position between standard wide-angle imaging and extreme fisheye imaging. This makes it suitable when broad coverage is required but excessive image deformation should be avoided.

Lens Selection Considerations

Before selecting this lens, confirm that your camera uses a 1/4″ image format and an M12×0.5 mounting interface. The 2.8mm focal length provides a relatively broad field of view, while the 0.2m minimum object distance makes it suitable for applications involving relatively close subjects.
