Imaging spectrometer is a kind of “remote sensing instrument” with the purpose of obtaining detailed spectral images of the Earth’s target, such as the radiation information of the earth and the sea and the monitoring of the atmosphere. Imaging spectrometer is characterized by multiple imaging bands, spectral discontinuities, overlapping positions, and the presence of image resolution and spectral resolution of the problem, the optical system is very complex, and the required spectral resolution than the image High resolution. The optical system principle, optical system design method and components of imaging spectrometer are introduced in detail. According to the existing technical conditions, the reasonable structure and design result are given, the design idea is novel and applicable
