略论紫外可见分光光度计对光栅的基本要求

Basic Reguirements for Grating in UV—VIS Spectrophotometer

本文详细讨论了紫外可见分光光度计对光栅的基本要求;分析了用于紫外可见分光光度计的光栅之输出能量、波长范围、杂散光和分辨率等方面的要求;对杂散光和分辨率的测试方法也作了简单讨论;本文可供从事紫外分光光度计、光栅单色仪设计以及研制光栅的工作者参考。

In this paper, basic requirements for grating in ultraviolet—Visible ( UV—VIS ) spectrophotometer are discussed in detail. This paper suggested the grating in UV—VIS spectrophotometer needs high output energy, wide wavelength range, small stray light and high resolution in the ultraviolet region and visble region. Meanwhile the methods of test for stray light and resolution of grating are discussed briefly in this paper This paper provided a reference for designers in the UV—VIS spectrophotometer, grating monochromator and some grating respects.
