摘　　要：根据色度学原理,利用USB2000+光纤光谱仪,量化常见红色宝石的色度学参数,通过比较分析可知,常见红色宝石在色度学方面呈现较明显的区别:具有近似色调角的红色宝石样品的明度L的值按照从大到小的顺序排列,分别为碧玺、尖晶石、石榴石、红宝石;具有近似色调角的红色宝石样品的色度a*和彩度C*的值按照从大到小的顺序排列,分别为碧玺、红宝石、尖晶石、石榴石,而色度b*的值按照从大到小的顺序排列,分别为石榴石、尖晶石、红宝石、碧玺。因此,利用光纤光谱仪、适当的照明方式及参数采集方法,应用色度学原理,可以对常见红色宝石在色度学方面进行初步对比分析。According to the principle of colorimetry, the color parameter indexes of familiar red gems are quantitated by the USB2000 ＋ fiber spectrometer. Through the comparative analysis, the familiar red gems present the obvious difference in colorimetry： With the approximate hue angle, the order of red gems＇ lightness, from big to small, are tourmaline, spinel, garnet and ruby; With the approximate hue angle, the order of red gems＇ color a ＊ and chroma C ＊ from big to small, are tourmaline, ruby , spinel, and garnet, the order of red gems＇ color b ~ , from big to small, are garnet, spinel , ruby and tourmaline. Therefore, it can make a preliminary comparative analysis on the familiar red gems of colorimetry by using the fiber-optic spectrometer and the appropriate method of lighting and parameter collection.
