本文叙述了激光拉曼分光计中杂散光的测试方法及获得杂散光“廓线”的步骤。在测试中考虑到激光拉曼分光计的特性和使测试结果与仪器实际运转情形相符,以便求得激光拉曼分光计实际降低杂散光的程度。为了使实验结果正确,文中还指出应注意事项。对激光拉曼分光计中影响杂散光的因素及测试杂散光的条件进行了研究,实验结果也发表于此。
This paper describes the testing method of stray light in laser Raman spectrometer and the steps of obtaining “profile” of stray light. Taking into account the characteristics of the laser Raman spectrometer in the test and the test results in line with the actual operation of the instrument in order to obtain the laser Raman spectrometer actually reduce the degree of stray light. In order to make the experimental result correct, the article also points out the precautions. The factors influencing stray light in laser Raman spectrometer and the conditions of testing stray light were studied. The experimental results are also published here.
