摘    要:为了实现更宽波段范围内的全谱直读并获得较高的分辨率,对中阶梯光栅光谱仪的分光系统进行了研究。简述了中阶梯光栅与中阶梯光栅光谱仪的基本原理,分析了中阶梯光谱仪和普通光谱仪的区别,详细论述了一种利用中阶梯光栅作为主要分光元件,棱镜作为交叉色散原件的中阶梯光栅分光光路的设计方法,并最终在探测面上得到了可探测分析的二维谱图。通过对设计过程的详细论述,可以为今后从事中阶梯光栅光谱仪光学设计的研究者提供参考。

关 键 词:中阶梯光栅  光谱仪  二维光谱  交叉色散

Abstract:In order to obtain high resolution spectra in a wider range, research on the spectrophotometric system of echelle spectrometers was conducted. The general theories of echelle gratings and echelle spectrometers were introduced briefly, the difference between the echelle spectrometer and ordinary spectral instrument was analyzed, the optical path of echelle beam splitter was designed by using principles of optical imaging, an echelle grating was used as the main spectral elementa and a prism was used to separate the overlapped diffraction orders as a cross disperser, and a two dimensional spectrum was obtained at the detection surface. It is wished that the detailed dissertation of the designing is useful for the research of the echelle grating spectrograph.
Keywords:echelle grating  the echelle spectrograph  two-dimensional spectrum  cross dispersion
