Optical-near infrared camera CASCAM (Chinese Academy of Sciences, Camera), employing with CCD and near infrared array HAWAII-1, is designed to make imaging simultaneously at the optical and infrared wavelengths in the 2.16 m optical telescope located at XingLong station. The system mechanical design includes optical box, vacuum box and cooling system. The optical box is the platform of optics and detectors, and it prevents thermal emission from outside effectively. The vacuum box is outside of the optical box, which can keep good vacuum at a level of 10-6 Torr. The vacuum box, vacuum pump and a refrigerator are composed as the cooling system of the camera.
