C-Mount Low Distortion Lens Applications

Core Application Scenes

This low distortion C-Mount lens is particularly suitable for machine vision applications where image geometry is more important than simply achieving the widest possible field of view. With TV distortion below 0.1%, straight edges and object shapes can be preserved with minimal geometric deformation, making the lens well suited to inspection tasks involving positional accuracy and dimensional consistency.

In automated production environments, the lens can be used for component inspection, part alignment, surface inspection, barcode or code reading, and visual positioning. The 6mm focal length and 60° horizontal FOV provide a practical balance between scene coverage and image detail for compact inspection stations.

The 0.1m minimum object distance is also useful when the camera needs to be installed close to the inspection target. Manual focus and iris adjustment allow optical parameters to be tuned according to working distance, object size and illumination conditions.

For systems where geometric accuracy is a major optical consideration, the Distortion Guide can help engineers understand how lens distortion affects machine vision measurements and image analysis.
