4.6mm 10MP M12 Ultra-Low Distortion Lens

The 4.6mm 10MP M12 Ultra-Low Distortion Lens is a compact fixed focal lens designed for high-resolution imaging systems that require accurate image geometry and controlled wide-area coverage. Featuring a 1/2.3″ image format, 10MP resolution, and optical distortion below 0.5%, this lens provides a strong balance between image detail and distortion control. Its 4.6mm focal length delivers an 82° diagonal FOV and 71° horizontal FOV, making it suitable for imaging relatively broad scenes without relying on an extreme wide-angle or fisheye configuration.

The lens uses an F4.5 fixed aperture, M12x0.5 mount, and compact Φ14 × 18.8mm mechanical design. With a 0.2m minimum object distance and 22.3mm TTL, it can be integrated into compact machine vision cameras, industrial inspection modules, embedded vision devices, and other space-constrained imaging platforms. The 3G2P optical construction provides a practical configuration for high-resolution compact imaging applications.

Low Distortion Lens Applications

Precision Machine Vision Inspection

The combination of 10MP resolution and <0.5% distortion makes this lens suitable for machine vision applications where image detail and geometric consistency are both important. The controlled distortion can help maintain the shape and relative position of objects within the captured image.

Potential applications include:

• Component inspection
• Surface inspection
• Object detection
• Visual measurement
• Automated quality inspection
• Industrial camera systems

Industrial Object Inspection

The 4.6mm focal length provides a relatively broad field of view while avoiding the extreme perspective associated with fisheye optics. Combined with distortion below 0.5%, the lens can be considered for industrial systems that need consistent image geometry across a wider inspection area.

It can be integrated into compact industrial cameras, automated inspection equipment, and embedded optical modules.

Embedded Vision Systems

The M12x0.5 mount and Φ14 × 18.8mm dimensions make this lens suitable for compact embedded camera designs. Its fixed focal configuration provides a straightforward optical setup for devices where mechanical space is limited and repeatable imaging performance is required.

Compatible device types may include:

• Embedded vision cameras
• Compact smart cameras
• Industrial inspection modules
• Machine vision cameras
• Automated detection equipment
• Compact imaging devices

Close-Range Imaging

With a specified 0.2m M.O.D., the lens can support imaging applications where the camera is installed relatively close to the target. Its 71° horizontal FOV allows the system to capture a broad portion of the scene while maintaining controlled distortion.

This configuration can be useful for close-range object inspection, compact equipment monitoring, and embedded visual detection.

Why Choose This Low Distortion Lens?

The key advantage of this lens is its strong distortion control in a compact 10MP M12 configuration. With distortion below 0.5%, it is particularly appropriate for vision systems where geometric accuracy is more important than achieving an extremely wide field of view.

The 4.6mm focal length provides 71° horizontal coverage, while the 10MP resolution supports detailed image acquisition. The compact Φ14 × 18.8mm form factor further helps simplify integration into small camera modules.

Compared with broader ultra-wide M12 lenses, this lens takes a more controlled approach to field coverage. It is therefore a good candidate for machine vision and industrial imaging systems that need a combination of high resolution, low distortion, moderate wide-angle coverage, and compact mechanical integration.
