Paper Abstract

A novel shortwave infrared imaging spectrometer based on free-form has been presented .The method was proposed for the requirement of lightweight and wide swath for aerospace loads .The theory of aberration was analyzed based on offner structure. Simulations have been performed by software to confirm the methods. The imaging spectrometer was designed with spectrum (950-2500nm), focal length of 70mm, and field view of 20 degrees. The pixel size is 15 microns. The performance shows the spectral resolution is better than 11nm, the spectral keystone is less than 1nm, the MTF< 0.5@33lp/mm .
