摘　　要：为研究在光谱响应度测量中使用的精密光栅单色仪McPherson的Model207的波长特性,介绍了为此建立的基于LabVIEW的光栅单色仪波长标定装置系统。通过RS232与GPIB总线接口将装置的各自动控制部件连接到计算机,实现光谱的自动标定;针对光栅单色仪的性能研究,编写了对应的性能实验程序;在程序中给出了对采集的数据进行处理分析。通过实验得到单色仪波长准确度能达到0.02nm。The new wavelength calibration system of the grating monochrometer was described to research the wavelength characteristic of Model 207 monochrometer which was used in the spectral responsivity measurement.The automatic parts of the facility were all connected with the computer by RS232 or IEEE-488.The wavelength calibration could be carried out automatically,and the monochrometer＇s performance was also tested.At last the method of processing acquisition data was introduced in the program.The experiment results show that the accuracy of the monochrometer wavelength is 0.02 nm.
