5mm C-mount spacer ring for CS-mount cameras

5 mm extension ring for using C-mount lenses on CS-mount cameras. It adds the required 5 mm spacing between the camera and lens, matching the flange distance difference between CS-mount and C-mount systems so compatible C-mount lenses can focus correctly on CS-mount cameras. It can also be used as a simple 5 mm spacer ring in compatible optical setups.
