Low Distortion Lens – CCL1235MP

CCL1235MP Low distortion 35mm M12 S-mount board lens 1/2″ HD long focal length rectilinear security

35mm 0.29% Low Distortion M12 Fixed Focal Lens for 1/2″ Sensors

This 35mm M12 fixed focal lens is designed for 1/2″ image sensors requiring a narrow field of view and highly controlled optical distortion. With a 12.5° diagonal FOV, F2.0 aperture, and distortion below 0.29%, it provides precise image framing for compact imaging systems, inspection equipment, embedded cameras, and other applications where accurate geometric representation is important. The M12x0.5 mount offers straightforward integration with compact camera modules.

Designed for precision imaging applications, this low distortion M12 lens combines a relatively long 35mm focal length with a compact mechanical design, making it suitable for systems that need tighter scene coverage without moving to a larger C-mount optical assembly.

Product Core Highlights

• 35mm fixed focal length provides narrow-angle imaging for tighter scene coverage.
• Low distortion below 0.29% helps maintain accurate image geometry.
• F2.0 aperture provides a relatively bright optical design for compact imaging systems.
• M12x0.5 mount supports integration into small camera modules and embedded vision devices.
• 0.5m minimum object distance provides practical focusing capability for relatively close inspection targets.

Low Distortion Lens Applications

This 35mm low distortion M12 lens is suitable for imaging systems where a narrow field of view and accurate spatial representation are more important than broad scene coverage. The 12.5° diagonal FOV allows the camera to concentrate on a specific target area, making the lens useful for applications requiring controlled framing from a relatively longer working distance.

Typical applications include compact inspection cameras, embedded vision systems, object recognition devices, measurement equipment, industrial monitoring cameras, and specialized machine vision modules. The low distortion specification of less than 0.29% is particularly beneficial when image geometry needs to remain consistent for visual inspection or measurement-related processing.

The fixed F2.0 aperture provides a stable optical configuration, while the M12x0.5 interface makes the lens appropriate for compact camera assemblies where installation space is limited. For applications involving sensor and field-of-view matching, the Sensor Guide and FOV Calculator can help engineers evaluate system compatibility.
