摘要
The optics for an integral field spectrometer based on a lenslet array is described. The principle behind the integral field spectroscopy of this system is introduced and partial modeling of the structure of the system is developed. A hybrid design method from physical optics and geometrical optics is used to design the system. Because the functions of the optical system before and after the lenslet array are different, the telephoto system and the spectrograph need to be separated. The optical system was then optimized using a combination design. This method is confirmed by simulation and comparison results and can be used in the design of other lenslet array integral field spectrometers.
