CIE 1931标准色度系统下红色系列尖晶石的色调划分

Tone analysis on the red spinel series in the context of CIE 1931 standard chromaticity system

使用USB2000+光纤光谱仪收集42颗红色尖晶石样品抛光面的漫反射信号,采用CIE 1931标准色度系统,对样品进行色度学研究。通过色度学参数的研究与实物对比,可将红色系列尖晶石的色调进行划分。紫色调尖晶石补色波长在545~569 nm;红紫色调尖晶石补色波长在509~545 nm;紫红色调尖晶石补色波长在495~509 nm;红色调尖晶石补色波长在493~495 nm、主波长在630~700 nm;橙红色调尖晶石主波长在598~630 nm;橙色调尖晶石主波长在588~598 nm。

There is not a standard discription on red spinel color,thus different descriptions may be used on the same spinel. The thesis collects the signals of diffuse reflection from the polished surfaces of 42 red spinel samples by USB2000 ＋ fiber optic and spectrum,studies the tone of samples on the basis of CIE 1931 Standard Chromaticity System. The study on chromatometry parameter and comparison between material objects divides the tone of red spinel series. The complementary color wave length of purple spinel is between 545-569 nm.The complementary color wave length of red purple spinel is between 509-545 nm. The complementary color wave length of purple red spinel is between 495-509 nm. The complementary color wave length of red spinel is between 493-495 nm. The color wave length of red spinel is between 630-700 nm. The color wave length of orange red spinel is between 598-630 nm. The color wave length of orange spinel is between 588-598 nm.
