摘　　要：介绍了一种应用于电脑配色系统的小型光谱仪。它根据分光测色的原理,使用 型凹面光栅作为其分光器件,石英光纤做测色探头,线阵CCD为探测器。详细介绍了实验仪器的硬件及软件系统,给出了波长标定方法,并进一步探讨了影响仪器准确性和重复性的因素以及解决办法。A mini-spectrometer that applied to computer color match system is introduced in the paper. Based on the principle of color measure, the mini-spectrometer uses concave grating as its light splitter, fiber as its color picker and liner CCD as its detector. The author describes the hardware and software system in details, gives the calibration method and analyses the causes that affect the accuracy and the stability of the spectrometer, then some methods are provided to solve corresponding problems.
