激光拉曼分光计中超低杂散光的测试

Measurement of ultra-low stray light in a laser Raman spectrometer

本文提出了一种测试激光拉曼分光计中超低杂散光的新方法.实验结果表明,本方法的杂散光测量限可达10^(-14)量级.

The stray light measurement is a difficult problem in specifying x the technical performance of a laser Raman spectrometer. This article suggests a new method of testing ultra-low stray light in a laser spectrometer. Experimental results show that, the stray light measuring limit of the order of 10-14may be achieved.
