C-Mount Lenses | Fixed Focal Length Lenses
C-Mount lenses are used in machine vision and industrial inspection as they are easy to adjust and are compatible with large global shutter sensors.
A C-Mount lens has a 17.52mm flange height. These lenses are known for their use with many cameras and are compatbile with different sensor sizes.
Our C-mount lenses use glass elements and are quality assured with accurate F#, resolution, EFL values. Use our lens calculators to identify your focal length requirements.
Our customers use our lenses with high performance machine vision cameras from Allied Vision, Basler, FLIR, iDS, The Imaging Source, Lucid Vision, and more.

Fast 2/3" C-Mount Lenses for 5MP Sensors
Our 2/3" 5MP lenses are suitable for 3.45um pixel pitch cameras with sensor diagonal of ~11mm such as IMX568.
2/3" C-Mount Lenses for 8MP-12MP Sensors
Our 2/3" C-Mount lenses are suitable for 1.85um~2.74um pixel pitch cameras with sensor diagonal up to 11.0mm such as the IMX264, GMAX2509, IMX250, IMX546, IMX568.
Choosing the Right C-Mount Lens
- Field of View: A shorter focal length is ideal for wide-angle applications, while a longer focal length is better suited for telephoto applications.
- Depth of Field: the depth of field of a lens determines the range over which objects are in focus.
- CMOS Sensor Format: the format of your sensor will determine which lenses will provide full coverage, or the crop ratio for FoV.
- Resolution: The lens MTF or sharpness needs to match the sensor's pixel pitch (size) otherwise you'll have a blurry image.
- F#: The amount of light that the lens collects is dependent on the aperture diameter.
