摘要
光学-近红外相机CASCAM(ChineseAcademyofScience,CAMera)采用光学CCD和近红外列阵HAWAII-1探测器,配备兴隆2.16望远镜可同时进行光学和近红外成像和偏振观测。CASCAM机械系统主要包括光学箱和真空箱以及致冷设计,光学箱是相机光学系统和探测器的载体,同时防止来自光学箱外部的红外热辐射;光学箱外部是真空箱,是整个系统的机械支撑,保证良好的真空密封性能,和真空泵、冷冻机一起构成了相机的致冷系统。
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.
