Low Distortion Lens – CCL125040MPF

CCL125040MPF Low distortion wide angle 4mm 1/2.5″ 74° M12 mount lens with HD 5MP for rectilinear scanning

4.0mm 5MP M12 Low Distortion Lens

This 4.0mm 5MP M12 low distortion lens is designed for compact imaging systems that require a broad field of view without compromising geometric accuracy. It provides an 86° diagonal FOV, 74° horizontal FOV, and 60° vertical FOV, giving cameras a wide perspective for capturing larger areas while maintaining optical distortion below 0.4%. The lens supports a 1/2.5″ image format and 5MP resolution, making it suitable for detailed imaging in embedded vision and inspection systems. Its F2.8 fixed aperture provides a consistent optical configuration, while the M12 × 0.5 mount enables integration with compact camera modules. With a 0.1m M.O.D., 22mm T.T.L., and 2G2P + IR Cut construction, this lens offers a practical combination of close-range imaging, controlled distortion, and compact system integration. Designed for low-distortion wide-angle imaging applications, this fixed focal M12 lens is suitable for machine vision, embedded inspection, robotics vision, and smart camera systems.

Embedded Inspection Cameras

With a 0.1m M.O.D., this lens can support close-range imaging where the camera needs to operate near the target. Its 4.0mm focal length and 86° diagonal FOV provide useful coverage for compact inspection modules, embedded cameras, and small-area monitoring equipment.

For selecting the appropriate lens based on sensor size, working distance, and FOV, refer to the Lens Selection Guide.

Robotics Vision

Robotic vision systems may require a wider perspective to observe objects, tools, or operating areas while maintaining sufficient geometric accuracy. The 4.0mm focal length and <0.4% distortion make this lens a suitable option for compact robotic camera modules used for positioning, recognition, and visual inspection.

See TOWIN’s Robotics Vision Solutions for more application-specific options.

Smart Camera Systems

The M12 × 0.5 interface makes the lens suitable for integration into compact smart camera platforms. Its 86° diagonal FOV can help increase scene coverage without requiring multiple cameras in applications where a single wide-view camera is preferred.

Wide-Area Embedded Imaging

The 86° diagonal, 74° horizontal, and 60° vertical FOV provide a relatively broad viewing range for fixed camera installations. This makes the lens suitable for embedded monitoring, compact vision modules, equipment observation, and other applications where capturing a wider area is important.
