摘要	According to the application demands of a color measuring spectrophotometer, the spectrometer composed of an optical system, a photoelectric receiving system and relevant circuits was proposed in a modular design to improve its facilitate design, alignment and test. As the spectrophotometer is a non-imaging optical instrument, every optical module was connected by optical fibers. The application requirements of the spectrophotometer were analyzed, its specifications were put forward, and spherical aberration and coma aberration were well corrected. A way to eliminate the secondary diffraction spectrum with an optical filter was analyzed in detail and the contradiction of unmatched numerical apertures between fiber optics and spectrometer was solved. A spectrometer with a dimension of 130 mm90 mm45 mm was established, and experimental test shows that the spectrometer achieves a spectral resolution of 2 nm in the whole band with the slit width of 50 m. The spectrometer wavelength is calibrated and the accuracy is less than 0.2 nm. The entire band of the spectrometer uses 401 pixels, which meets the design requirements of the wavelength interval of 1 nm. The spectrometer with flexible fiber optics and electronic circuit is convenient for the layout of whole instrument, disassembly of modules and the individual test of the spectrometer, which lays a good foundation for the development and test of the whole spectrophotometer. , 2015, Chinese Academy of Sciences.
