Low Distortion Lens – CCL120845MPF

CCL120845MPF Low distortion 8.45mm 44° 1/2″ M12 mount lens with HD 5MP rectilinear scanning

8.45mm 5MP M12 Low Distortion Lens

The 8.45mm 5MP M12 Low Distortion Lens is designed for compact machine vision, industrial inspection, and embedded imaging systems that require accurate image reproduction and reliable coverage of a 1/2″ sensor. With an 8.45mm fixed focal length, this M12 lens provides a 55° diagonal FOV and 44° horizontal FOV on a 1/2″ sensor, while maintaining distortion below -1.49%. Its 5MP resolution capability supports detailed image capture for object inspection and recognition. The F2.8 fixed aperture, 0.1m minimum object distance, and integrated IR cut filter make this lens suitable for compact visible-light imaging devices.

Designed for low-distortion machine vision applications, this lens combines a compact M12 interface with controlled geometric distortion and practical field coverage. It can be integrated into space-constrained industrial cameras, smart cameras, inspection equipment, and other embedded vision platforms.

Smart Camera & Embedded Vision

The M12 × 0.5 interface and 15.34mm TTL make this lens suitable for compact imaging architectures where optical size and integration flexibility are important. Its fixed aperture and integrated IR cut filter support consistent visible-light imaging in embedded camera designs.

Compatible devices: smart cameras, embedded cameras, compact inspection cameras, and edge vision devices.

See the M12 Lens Solutions for additional compact lens options.

Object Recognition Systems

With 5MP resolution and distortion below -1.49%, the lens can support recognition systems that need clear image details while keeping geometric deformation controlled. The 8.45mm focal length is suitable for applications requiring a moderate field of view rather than an extremely wide perspective.

Compatible devices: object recognition cameras, automated inspection cameras, access-control imaging devices, and industrial recognition modules.

Why Choose This 8.45mm M12 Low Distortion Lens?

This lens is a practical choice when a compact M12 optical solution needs a combination of 5MP resolution, controlled distortion, 1/2″ sensor coverage, and a moderate field of view. Compared with ultra-wide M12 lenses, its 55° diagonal FOV provides a more controlled perspective that can be advantageous for inspection and object recognition.

The integrated IR cut component is also appropriate for visible-light imaging systems where unwanted infrared wavelengths need to be filtered rather than optically focused. For a better understanding of distortion requirements, refer to TOWIN’s Distortion Guide.

Frequently Asked Questions
