C/CS-Mount Lens
What is C/CS-Mount Lenses
A C-Mount is a type of lens mount commonly found on CCTV cameras, machine vision cameras, and microscopes. C-mount lenses provide a male thread, which mates with a female thread on the camera. The thread is nominally 1 inch (25.4 mm) in diameter, with 32 threads per inch (0.794 mm pitch).
Tip
The flange focal distance is 17.526 millimeters (0.6900 in) for a C-Mount. CS-Mount has a flange focal distance of 12.526 millimeters (0.4931 in) but is otherwise the same as C-Mount, including the fact that lenses for many different formats are made for it.
CS-Mount lenses are generally built for the smaller formats.
CS-Mount to C Mount Adapting
Since CS-Mount is basically the same as C-Mount except for the flange focal distance, you can adapter a CS-Mount to C Mount by adding a 5mm C-CS adapter to a CS-Mount to use with C-Mount lenses.
However, it’s not possible to easily use a CS-Mount lens on C-Mount, because the back focal length won’t match.
Therefore, if you find you cannot manage to focus a CS-Mount lens, check if you leave the 5mm C-CS adapter on the thread.
CS-Mount to M12 (S-Mount) Adapting
In some circumstances, you might want to convert the C/CS-Mount to an M12 mount. There are two ways to achieve that depending on the type of the CS Mount to be adapted.
If you are using Arducam camera modules with CS-Mount, you can easily replace the CS-mount with an M12 mount by changing the lens holder.
Most of Arducam camera modules are compatible with 18mm and 20mm hole spacing, which match the majority of the lens holder’s. Here is a video showing how to do that.
The Raspberry Pi High Quality Camera, on the other hand, is not the same case. It’s lens holders – officially called the main housing – is not designed to be easily interchangeable.
Not only because the IR filter is glued to the holder, but the hole spacing is also not a standard figure.
Therefore, to adapter a CS-mount camera like this, you need an M12 to CS-Mount adapter. Here is an illustration of how that works.
C/CS-Mount to DSLR Lens Adapting
Arducam offers C Mount adapters for Canon and Nikon lenses. Therefore, the C-CS adapter is required if you are using the DSLR lenses on a CS-Mount camera.
