可见分光光度计的波长定位原理与实现

Principle and Realize of Spectrophotometer's Wavelength Location

文章介绍了 72 3型可见分光光度计的整机结构、工作原理和单色光的光学系统 ,重点分析了单色的产生机制以及波长定位和驱动。并给出了实现产生 32 0 nm～ 82 0 nm,波长可读精度为 0 .1nm的单色光的方法。

The structure and principle of spectrophotometer were introduced and the optical system of monochrome was analyzed particularly in this paper.The method of generating monochrome was given in detail.
