摘要
为了克服传统光栅光谱仪小体积与高分辨率无法共存的缺点,提出一种以中阶梯光栅为核心色散元件、反射棱镜为辅助色散元件的光谱仪光学设计方法。具体分析了中阶梯光栅的基本原理,从光路设计和元件参数设计两方面进行仪器光学设计,最后设计了一个焦距为150 mm、光谱范围为200 nm~600 nm、理论光谱分辨能力为0.1 nm的中阶梯光栅光谱仪,仿真和实验表明,设计的光谱仪在Hg灯253.652 nm处光谱分辨能力为0.023 9 nm,在Hg灯546.074 nm处光谱分辨能力为0.061nm,满足设计指标要求。
In order to overcome the shortcomings of the demand for small size and high resolution cannot be meet at the same time for conventional grating spectrograph,an optical design method of spectrograph based on the echelle as the core dispersion element and the reflection prism as the auxiliary dispersion element is proposed. Firstly,the basic principle of the echelle is analyzed in detail; Secondly,the optical design of the instrument is carried out from the aspects of optical path design and component parameter design; Finally,an echelle spectrographwith a focal length of 150 mm,a spectral range of 200 nm ~ 600 nm and a theoretical spectral resolution of 0.1 nm is designed.The simulation and experimental results show that the spectral resolution of the designed spectrograph is 0.023 9 nm at Hg 253.652 nm and 0.061 nm at Hg 546.074 nm,which meets the requirements of design specifications.
