一种 LED 冷光源光学性能检测用光纤光谱仪的研制

摘要

以石英汞灯为溯源标准，将光源接收装置、光纤、光谱仪结合在一起，建立以 LED 冷光源作为光源及单色器的快速分析仪器的光学计量性能检测的量传方法，实现了快速分析仪器波长准确度、重复性和光谱带宽等光学性能的检验。%A quartz lamp is used as traceability standard,the apparatus consists of light receiving de-vice,optical fiber and spectrometer.It can measure the instrument wavelength accuracy,repetition and spectral bandwidth of LED cold light source rapidly.
