Low Distortion Lens – CCL13040MP

CCL13040MP Low distortion wide angle 4mm M12 mount lens 1/3″ with HD 3 Megapixel for rectilinear scanning

4mm 5MP M12 Low Distortion Lens for Precision Imaging

This 4mm 5MP M12 low distortion lens is designed for compact imaging systems that require high-resolution image capture and highly accurate geometric reproduction. With a 1/3″ image format, 76° diagonal FOV, 64° horizontal FOV, and optical distortion below 0.2%, this fixed focal lens provides excellent image geometry for inspection, measurement, monitoring, and embedded vision applications.

The F2.8 fixed aperture offers a practical balance between light transmission and optical stability, while the M12×0.5 mount supports integration with compact camera modules. With a 0.1m minimum object distance, 22mm TTL, and Φ14 × 18.7mm dimensions, this lens combines low distortion performance with a compact mechanical design.

Product Core Highlights

• 5MP high-resolution imaging supports detailed image capture for compact vision systems.
• Ultra-low distortion below 0.2% helps preserve object shape and image geometry with minimal optical deformation.
• 4.0mm focal length with 76° diagonal FOV provides broad scene coverage while maintaining controlled distortion.
• 0.1m minimum object distance supports close-range inspection and object imaging.
• Compact M12×0.5 design with Φ14 × 18.7mm dimensions simplifies integration into space-constrained camera modules.

Low Distortion Lens Applications

This 4mm M12 low distortion lens is particularly suitable for imaging applications where accurate image geometry is more important than simply maximizing field of view. Its distortion specification below 0.2% helps reduce the curvature and deformation of straight lines and object edges, making it a strong choice for compact inspection and measurement-oriented camera systems.

Typical applications include machine vision inspection, dimensional inspection, object measurement, barcode and code inspection, industrial automation cameras, embedded vision modules, smart monitoring systems, and compact optical inspection equipment. The 76° diagonal FOV provides useful coverage for close-range scenes while the 4.0mm focal length maintains a relatively natural perspective.

The 0.1m M.O.D. also allows the camera to be positioned relatively close to the target, which is useful for compact inspection equipment and embedded imaging devices. The M12×0.5 interface and Φ14 × 18.7mm housing make the lens suitable for camera designs where optical performance and mechanical space must be considered together.

Compatible devices: 1/3″ CMOS camera modules, 5MP industrial cameras, M12 camera boards, compact machine vision cameras, inspection modules, embedded vision devices, and other imaging systems equipped with an M12×0.5 lens interface.
