近年来,由于激光拉曼光谱技术和同位素分离等工作的迸展,对光栅单色仪提出了很高要求。为适应这类研究工作的需要,长春光机所研制了一种高性能的光栅双单色仪(图1)。该仪器具有波段范围宽、分辨率好、波长准确度高、杂散辐射小、自动化程度较高等特点,既可做双单色仪用,又能做单单色仪用。它配上适当的辐射源、探测器等附件,可构成分光光度计、荧光光度计等各种光谱仪器,用以测量辐射源的光谱分布、探测器的光谱灵敏度、
In recent years, due to the progress of laser Raman spectroscopy and isotope separation work, the grating monochromator has put forward high requirements. In order to meet the needs of such research work, Changchun Guangji developed a high-performance grating double monochromator (Figure 1). The instrument has a wide band range, good resolution, high wavelength accuracy, stray radiation, high degree of automation and other characteristics, can do dual monochromator, monochromator can do with. It coupled with the appropriate radiation sources, detectors and other accessories, can form a spectrophotometer, fluorometer and other spectrometer, to measure the spectral distribution of the radiation source, detector spectral sensitivity,
