Size: thread 25.4 mm (1 inch)



Suitable for surveillance cameras C mouth, but the CS lens, so use this adapter ring at this time



What is a C - CS adapter ring, C type installation from datum to focus distance is 17.562 mm, CS is apart from the focal distance of 12.5 mm. If you want to install a C a camera mounted to a CS installed a video camera, you need to use the lens converter. This converter is called \"C - CS connecting link.

By camera is threaded mouth in all types of camera lens, CCD camera lens fitted with two kinds of industry standard, namely the installed C and CS. Both threaded part of the same, but the distance from the lens to the photosensitive surface difference. Two main lens installation standards, respectively is C - mount and CS - mount. They all have a 1 inch long thread and looks very similar. Their different is because after installed to the camera lens, lens into the Spaces between the sensors:

CS - mount: the distance between the image sensor to the lens should be 12.5 mm

C - mount: the distance between the image sensor to the lens should be 17.5 mm. A 5 mm washer (C/CS link) can be used to C - mount lens into CS - mount lens

C - mount is the original standard, the CS - mount is on the upgrade, the upgrade can reduce manufacture cost and decrease the size of the sensor. Now on the market the majority of the camera and lens are using CS - mount standard. By using C/CS link install an old C - mount lens to the camera with CS - mount interface. If the camera can't focus, may be because of the wrong type of lens.
