Actual star image adding optical cross-talk effect of CMOS(Complementary Metal Oxide Semiconductor)  detector is simulated by non-sequential ray tracing in ZEMAX optical design and analysis software to evaluate its performance. The distortion relative to image spot centriod is introduced and calculated by simulated star images  which is less than 0.03% of lens in this paper. Thermal adaptability is discussed by opt-mechanic thermal analysis  which shows the RMS spot radius of marginal filed changes less than 0.7m under 10C temperature gradient  and changes less than 1m during homogeneous temperature changing from 40C to 40C. The results of analyses and simulations show the design of this lens can achieve the requirement of high precision CMOS star sensor well. 2011 IEEE.
