| Abstract: | Optical-Near Infrared Camera CASCAM (Chinese Academy of Science, CAMera), employing CCD and near infrared array HAWAII-1, is designed to make imaging simultaneously in the optical and infrared wavelengths with the 2.16 optical telescope at XingLong station. The system mechanical design include optical box , vacuum box and cooling system. The optical box is the platform of optics and detectors, and prevent from outside thermal emission effectively. The vacuum box is outside of the optical box, can keep good vacuum at a level of 10-6 Torr. The vacuum box, vacuum pump and a refrigerator are composed of the cooling system of the camera. |
