C-Mount – standard for industrial cameras
C-mount cameras
Industrial cameras are a key factor in each machine vision system. Most of them are “C-mount cameras” but many people do not know what it exactly means. Under the “C-mount” name hides the female thread, size 1 inch (25,4 mm) with 32 threads per inch.
C-mount cameras are the most popular among the industrial cameras, therefore there is a wide range of models available on the market. Avicon offers very reliable and reasonably priced Basler cameras which can satisfy demands of nearly every application requiring a machine vision system. Basler is a camera manufacturer with the highest number of cameras sold which just proves the quality of these cameras.
C-mount lenses
The term “C-mount lens”, although important, does not say much about the use of a lens. Among C-mount lenses you can find macro lenses as well as wide lenses – it depends on the focal length of the lens and the sensor size of the camera.
The leading lens manufacturers are Kowa and Azure. Their products are robust and their expected lifetime is very long.
C-mount vs CS-mount vs S-mount
C-mount thread is not the only type among machine vision cameras and lenses. Another solution, although less popular, is CS-mount. This type of thread differs from a C-Mount thread only with a flange to sensor distance – in CS-mount this distance is 5 mm shorter than in C-mount. CS-mount cameras are often used in surveillance systems.
S-mount is the least common thread type and it is often used in CCTV applications as well. S-mount is a M12 metric thread with 0,5 mm pitch. The benefits of this type of thread are small size and ability to work with very small sensors (from 1/6 inch to 2/3 inch).
Adapters
C to CS adapters allow for using a C-mount lens with a CS-mount camera. It is worth nothing, that it is not possible to use a C-mount camera with a CS-mount lens. It is caused by a lens thread being too short compared to a camera thread, which result in inability to completely screw the lens in.
CS to S adapters allow for using a S-mount lens with a CS-mount camera. One thing to remember is to check if the S-mount lens is designed to work with the sensor of the CS-mount camera.
