摘要

凹面光栅同心光谱仪中同心系统的物面和像面位于同一平面，且物像垂轴距离仅有几毫米，限制了实际系统中焦平面探测器和前置成像系统的摆放。为了解决此问题，在光学系统中引入平面反射镜将光线偏折，实现物面和像面的分离。根据平面反射镜偏转光线不同，设计了两种改进式凹面光栅同心光谱仪：物面转移式与像面转移式，利用仿真软件对这两种改进的光学系统设计进行了对比分析。结果表明：两种设计均能实现物面与像面的分离，分离距离均大于16 mm，且像差均得到较好的控制，在400~800 nm内全波段波像差曲线几乎为0，满足实际应用中低像差、高成像质量、物像面分离的要求，有效解决了器件摆放问题。

Abstract

The object plane and image plane of concave grating concentric spectrometers are in the same plane

and the vertical axis distance between object and image is only a few millimeters

which limits the arrangement of focal plane detectors and front lens. In order to solve this problem

a plane mirror was introduced into the optical system to deflect the light

and the separation of the object surface and the image surface was realized. According to the deflection light

two improved concave grating concentric spectrometers with shift object plane or shift image plane were designed and then simulated by simulation software. The simulation results show that the two spectrometers can achieve the separation of object surface and image plane

the separation distance is greater than 16 mm

and the aberrations are also well controlled

within the 400-800 nm the aberration curve is almost zero. Those results meet the application requirements of low aberration

high image quality

image plane separation

which can effectively solve the problem of device arrangement.
