摘要	To satisfy the requirements of space ultraviolet autonomous navigation sensor, a method based on usual glass combination was proposed to supersede costliness special glass such as CaF2. An ultraviolet star sensor was designed, whose waveband was 330-365 nm, F number was 1.6 and field of view was 88. The ghost suppression target was calculated by paraxial ray tracing. The paraxial first-order ghost was preliminarily analyzed and estimated by Code V, then the off axis multi-orders ghost and energy distribution was simulated by non-sequential ray tracing technology. The results show that this optical system has compact structures and high image quality. The dispersion spot radius is smaller than 10 m, and relative distortion is less than 0.05%. With a target dynamic range of 7 magnitudes, the ghost irradiance of the brightest star is 1/21 of the darkest star and meets the requirements of ultraviolet star sensor. 2016, Editorial Board of Journal of Infrared and Laser Engineering.
