Select A C-Mount Lens For Your Machine Vision Camera

C-Mount Lenses | Fixed Focal Length FA Lenses

C-mount lenses are lenses that have a 17.52mm flange height. These lenses are known for their interchangeability, adjustable F# and large format size.

C-Mount lenses are used in machine vision and industrial inspection as they are compatible with high resolution global shutter sensors.

Our C-mount lenses are quality assured with accurate F#, resolution, EFL values, with ready to download files.

Our customers use our lenses with high performance machine vision cameras from Allied VisionBaslerFLIR, iDSThe Imaging Source, Lucid Vision, and more.

Our lenses range from 1mm to 50mm EFL and 5° to 230°. The types of M12 lenses include fisheye, wide-angle, no-distortion, and telephoto. Each of our lenses is available with, or without, an IR cut off filter.

These can be used with embedded vision systems and imaging devices from Allied Vision, e-con SystemsFLIR, iDS, Basler, The Imaging Source, Lucid Vision, and more.
