Low Distortion Lens – CCL123042MPF

CCL123042MPF 4.2mm Wide Angle 12MP M12 low distortion lens with <0.2% distortion, 74° FOV and 0.2m MOD for precision machine vision systems.

4.2mm 12MP M12 Ultra Low Distortion Wide Angle Lens

The 4.2mm 12MP M12 Ultra Low Distortion Wide Angle Lens is designed for compact imaging systems that require high-resolution image capture, broad scene coverage, and highly accurate image geometry. Supporting a 1/2.3″ image format and 12MP resolution, this fixed focal lens provides an 86.2° diagonal, 74° horizontal, and 60° vertical field of view. With distortion specified at less than 0.2%, it delivers exceptionally controlled geometric performance for machine vision and industrial imaging applications where image shape and positional accuracy are important.

The lens features an F3.0 fixed aperture, M12x0.5 mount, and 0.2m minimum object distance. Its 21.84mm TTL and compact Φ15.31 × 14.5mm dimensions allow integration into space-constrained camera modules. The 3G2P+IRF lens construction provides a compact optical configuration for high-resolution imaging. Designed for precision machine vision and industrial inspection applications, this lens combines 12MP imaging, wide-angle coverage, and ultra-low distortion in a compact M12 format.

M12 Low Distortion Lens Application

Precision Machine Vision Inspection

The lens is particularly suitable for machine vision systems where low geometric distortion is important. With distortion below 0.2%, the lens helps preserve the shape and relative position of objects across the image. This makes it suitable for automated inspection, object positioning, alignment, dimensional analysis, and visual quality control.

Industrial Inspection & Object Detection

The 74° horizontal FOV provides broad scene coverage without relying on an extremely short focal length. Combined with 12MP resolution, the lens can be used in industrial cameras that need to capture multiple objects or a relatively large inspection area while retaining detailed image information.

Compact Embedded Vision

The M12x0.5 mount, compact dimensions, and 21.84mm TTL make this lens suitable for space-constrained embedded imaging equipment. Potential devices include compact smart cameras, embedded vision modules, industrial inspection cameras, robotic vision modules, and other small-form-factor camera systems.

For guidance on matching lenses with sensors and application requirements, refer to the Lens Selection Guide.

Close-Range Wide-Area Imaging

With a 0.2m minimum object distance, the lens can capture relatively nearby targets while maintaining a wide field of view. This makes it useful when camera installation space is limited but the imaging system still needs to cover a broad target area.
