摘要

Offner凸面光栅成像光谱仪分光系统的三个球面反射镜拥有共同的球心，这种同心特性能够使光谱仪具有无像散、谱线弯曲小、色畸变小、数值孔径大、结构简单等优点，而高精度的同心装调技术则是实现这些优点的关键。将双光束干涉基本原理与同心光学系统基本特点相结合，提出了适用于Offner凸面光栅成像光谱仪的干涉装调法，利用此方法对凸面光栅成像光谱仪同心光学系统的两个凹面反射镜进行同心装调，采用谱图直读法确定光栅位置，实现了Offner凸面光栅成像光谱仪的高精度同心装调。实验结果表明

经干涉法装调后，分光系统主镜和三镜的球心距离精度可以达到几个纳米甚至更高。

Abstract

Spectral system of Offner imaging spectrometers with convex grating utilizes only three spherical and centred surfaces achieving anastigmat

small spectral and spatial distortion

compact size and large numerical aperture. Concentric alignment with high precision is the key to realize these advantage. Based on the principle of dual-beam monochromatic interference and concentric system

interferometrical optics alignment for Offner imaging spectrometers with convex grating is given.With this method

the primary and tertiary mirror of Offner imaging spectrometers achieve concentric

the convex grating is arranged according to reading spectrogram directly and concentric alignment with high precision is realized. By the result

interferometrical optics alignment can achieve the distance between centers of the primary and tertiary mirror of Offner imaging spectrometers several nanometer or near zero.
