设计了一种宽谱段前置光孔远心光学系统，其孔径光阑位于透镜组的焦面上，该设计集宽谱段自动复消色差、长工作距、前置光孔及远心等特点于一体. 讨论了这样一种特殊光组的设计. 选用国产牌号的光学玻璃配对，价格低廉且在校正色差后，自动校正宽谱段二级光谱，并实现了透镜组两侧同时具有长工作距. 设计结果表明，光学系统的残余二级光谱很容易控制在千分之一焦距以内，波面平行差小于0.000 22弧度.

The basic principle, design scheme, technology measure and characteristic, the design result and imaging evaluation of the CCD stereo camera and the imaging interferometer spectrometer were presented, which are the main loads of the Chang′e-1 satellite used to detect the moon for the first time. The CCD stereo camera consists of a wide-field-view angle lens and a piece of area array CCD, and it is compact in size, light in weight, high in registration accuracy, and strong in adaptability for the space environment. The adjustment of the light exposure in the same orbit according to different latitudes can be achieved by the 16 types of combinations with 4 types of time exposure and 4 types of electronics gains. The techniques, including the large-scale reduced image transmission, the joint of 2 by 2 pixels, rectangle aperture stop, and 6 types of light exposure adjustment techniques with 2 types of light exposure and 3 types of electronics gains, were used in the imaging interferometer spectrometer. The good performance of CCD stereo camera and imaging interferometer spectrometer proves that the technique are effective.
