  The system is composed of an off-axis Three-Mirror Anastigmatic(TMA) telescope and two Offner convex grating spectrometers. By changing the magnification of two spectral imaging systems, two array detectors with different pixel sizes can be matched.

  该系统由离轴非球面三反射镜望远成像系统和两个Offner凸光栅光谱成像系统组成,通过改变两个光谱成像系统的变倍比来实现两种探测器的匹配。
