Paper Abstract

High resolution and large relative aperture have been urgent demands for the development of spectrometer. A design method of freeform was presented based on offner structure, The design of large relative aperture was realized by multi variables of freeform surface, the energy of system was doubled. The simulation was carried out by the methods. Spectrum of the system is 400~1000nm, the relative aperture is 1/2.4, the length of the slit is 20mm, and the number of spectral is 213. Based on the aberration theory, the system was optimized and the processing feasibility was analyzed. The analysis results show that the optical MTF of each wavelength is more than 0.7@42lp/mm, and the structure was compact. The system has the feasibility of processing and meets the needs of remote sensing.
