| Abstract: | A high resolution, dual field-of-view optical system is introduced. The optical system chooses re-imaging optics configuration and rotate-in mode, the operating waveband of the system is 3～5 μm, F/# is 2, and the zoom ratio is 4×. A 640×512 staring cooled infrared detector with 15 μm pitch is used in this system. The design results proved that this system has high image quality in both field-of-view, and the analysis of narcissus and tolerance are listed in the end. |
