　　The dark current noise existing in the CCD of the astronomical observation camera has a serious influence on its working performance,reducing the working temperature of CCD can suppress the influence of dark current effectively.By analyzing the relationship between the CCD chip and the dark current noise,the optimum working temperature of the red band CCD focal plane is identified as-75□.
