The dualband/dualFOV optical system can improve the detection capability of an IR system.The optical design theory of dualband/dualFOV telescope system was studied and a dualband/dualFOV telescope system was designed.The system can switch between the FOVsand three kinds of optical material were usedincluding GeZnSe and BaF2.The simulation result shows that the system has simple structure and fine imaging qualityand the MTF value is higher than 0.5 at the spatial frequency of 16 lp/mm.
