C-Mount Lens – C0611018M20

C0611018M20 is 6mm High-Quality Wide-angle C-Mount lens, manual iris, 20-Megapixel Low distortion lens, High resolution Industrial Lens.

20MP 1.1″ C-Mount 6mm Wide Angle Low Distortion Machine Vision Lens

This 20MP 1.1″ C-Mount machine vision lens combines a 6mm focal length with an exceptionally wide 118° diagonal field of view and less than 2.5% TV distortion. Designed for high-resolution industrial imaging, it provides broad scene coverage while maintaining controlled geometric distortion for demanding vision applications.

The lens supports 1.1″ image sensors and up to 20MP resolution, making it suitable for high-detail imaging systems that require both a large image area and wide-angle coverage. Its F1.8–16 manual aperture provides flexible exposure control, while manual focus and a 0.1m minimum object distance support close-range imaging and system-level optical adjustment.

For applications requiring precise field coverage, users can also refer to the Lens Selection Guide and FOV Calculator to evaluate focal length and viewing requirements before integration.

C-Mount Machine Vision Lens Applications

Core Application Scenes

This 20MP C-Mount wide angle lens is designed for industrial imaging systems where a conventional narrow-field lens cannot capture enough of the target area from a limited installation distance. Its 105° horizontal and 86° vertical FOV allow a single camera to cover a broad inspection zone while retaining 20MP image detail.

In factory automation environments, the lens can be used for large-area visual inspection, assembly-line monitoring, component positioning and robotic workspace observation. The <2.5% TV distortion specification is particularly useful when image geometry needs to remain controlled across a wide field of view.

The 0.1m minimum object distance also makes the lens suitable for compact inspection stations where the camera must be installed relatively close to the inspected object. Manual focus and manual iris adjustment allow optical parameters to be tuned during machine setup according to working distance and illumination.

For applications involving robotic inspection and large working areas, this lens can be integrated into Robotics Vision solutions where wide scene coverage and high-resolution image data are required.
