C-Mount Lenses | Fixed Focal Length Lenses
A C-Mount lens is a lens with a standardized 1"-TPI32 threaded flange. These lenses are used in machine vision and traffic applications as most have adjustable focus and adjustable aperture. These lenses can cover large sensors such as 1.2" global shutter sensors.
Most factory automation "FA Lens" C-Mount lenses have moving optical element groups which compensate for changes in optical aberrations as the working distance changes.
The difference between C-Mount vs CS-mount is that C-Mount cameras have a 17.52mm flange height where CS-mount cameras have shorter flange height of 12.526mm.
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.
