摘要
介绍了光学多通道分析仪 (Optic Multichannel Analyzer,OMA)的基本组成和工作原理 ,着重分析了OMA系统中光谱仪的狭缝宽度、光栅参数和 CCD的像素尺度对 OMA系统分辨率的影响。得到的结论是 :OMA系统的分辨率是由系统中分辨率最低的环节决定的 ,无限制地减小狭缝宽度无助于系统分辨率的提高。
The basic configuration of Optic Multichannel Analyzer is introduced in the article The change of the slit width, the parameters of grating and the pixel dimension of CCD that affect the resolving power of OMA system are analyzed The results obtained as follows: The resolving power of OMA system is determined by the lowest resolving power of each link in OMA, and it can not help raising the resolving power of OMA by changing the slit width smaller unlimitedly
