Paper Abstract

CCD star tracker is a key equipment of satellites. It works at a broad range of wavelength, from visible wavelength to near infrared. Here we just try to analyze the influence of aberrations based on an actual system (focal length: 120mm, F number: 1.3, field of view: 12deg, wavelength range: 0.45 micron to 0.85 micron). A double Gauss system is used to decrease the chromatic aberration while other aberrations are also controlled very well. The result shows that we can get some conclusions about the influence of coma which is the most significant aberration in this system.
