Abstract: In order to meet the practical requirement of airborne searching and tracking systems, a dual field-of-view imaging spectrometer with filters was designed based on the theory of zoom system and imaging spectrometer.The CCD of 1/3 inches was used, and the size of the pixel was 6.0 m6.0 m .The initial structure was obtained by using the Gaussian method, the system was optimized by using Zemax software. Dual waveband (0.45 m~0.7 m/0.6 m~0.95 m) clear imaging was achieved, axial moving group could complete double field-of-view switch(139.75/32.25). In this process, F number was 5.6 and constant. The design results show that the distortion of the wide-FOV is less than 3.5%, the distortion of the narrow-FOV is less than 0.2%, The peak values of MTF are more than 0.5 at Nyquist 50 lp/mm and the minimum back intercept range of the system is greater than 35 mm to install filters, which meets the assembly requirements.
