25mm M12 Low Distortion Lens Applications

Core Application Scenes

This 25mm M12 low distortion lens is designed for imaging systems that need to concentrate on a defined target area rather than capture a wide scene. Its 25mm focal length produces a 16° diagonal FOV on a 1/2.7″ sensor, making it suitable for applications where the camera is positioned at a moderate working distance and the target occupies a relatively focused portion of the image.

The less-than-3% distortion specification helps maintain controlled image geometry across the captured scene. This makes the lens suitable for fixed-position inspection, object recognition, code reading, and embedded industrial cameras where consistent imaging performance is more important than wide-area coverage.

The F2.0 fixed aperture provides a straightforward optical configuration for compact camera modules, while the M12 × 0.5 mount supports integration into small camera housings and embedded vision equipment. With a 0.5m minimum object distance, the lens is particularly suitable for applications where the camera is installed at a defined distance from the inspection target.

For engineers determining whether a 25mm focal length provides sufficient coverage, the FOV Calculator can be used to estimate the visible area based on sensor and working-distance requirements. The Focal Length Calculator can also help compare alternative focal lengths during camera system design.
