Low Distortion Lens – CCL11812MPR4

CCL11812MPR4 is Achromatic low distortion M12-mount 12mm lens for 1/1.8″ sensors, featuring F4.0 aperture and 5-megapixel high-resolution performance.

12mm M12 5MP Low Distortion Industrial Lens

This 12mm M12 low distortion lens is designed for compact industrial and machine vision systems using 1/1.8″, 1/2″, or 2/3″ image sensors. With 5MP resolution, less than -1.5% TV distortion, and a compact Φ14 × 11.30mm design, it provides controlled image coverage for embedded vision, inspection, and space-constrained imaging devices.

For engineers selecting a lens according to sensor format and image coverage, the Sensor Guide provides useful background on sensor compatibility. The Lens Selection Guide can also help determine the appropriate focal length and optical configuration.

Product Core Highlights

• 12mm fixed focal length for controlled compact-system imaging.
• 5MP resolution for detailed industrial image capture.
• Low distortion below -1.5% for improved geometric image reproduction.
• M12 × 0.5 mount for compact embedded vision equipment.
• Φ14 × 11.30mm housing for space-constrained camera designs.

As part of the M12 Lenses range, this compact optical design is well suited to embedded industrial cameras where mechanical space is limited but controlled distortion and reliable image detail are still required.

M12 Low Distortion Industrial Lens Applications

Core Application Scenes

This 12mm M12 industrial lens is designed for compact imaging systems that require a moderate field of view without the geometric distortion associated with more extreme wide-angle optics. On a 1/1.8″ sensor, it provides a 41° diagonal, 33° horizontal, and 25° vertical field of view, making it suitable for capturing a defined inspection area while maintaining controlled image geometry.

The lens is particularly suitable for embedded machine vision equipment, compact inspection cameras, smart devices, and automated imaging modules where the available installation space is restricted. Its Φ14 × 11.30mm dimensions allow optical integration into compact camera housings without requiring the larger mechanical envelope often associated with conventional industrial lenses.

The low distortion performance below -1.5% is useful when straight edges, component shapes, relative positions, or image geometry need to remain accurately represented. This makes the lens suitable for visual inspection, object positioning, barcode or code reading, and other industrial vision tasks where image geometry contributes to reliable image analysis.

The fixed F4.0 aperture provides a stable optical configuration for systems operating under controlled illumination. With a relative illumination specification above 83%, the lens is also designed to maintain useful brightness toward the image periphery, helping produce more consistent image quality across the captured scene.

For system designers determining the required viewing area from sensor size and working distance, the FOV Calculator can be used during the lens selection process.
