镀膜玻璃色差研究

Study on Colour Difference of Coated Glass

分析了镀膜玻璃产生色差的原因，利用分光光度计对镀膜玻璃进行了光谱反射比的测量，讨论了视场、色空间和标准照明体对色差计算值的影响，提供了一种镀膜玻璃色差测定值的确定方法。

This paper discusses the reasons of existing colour difference of coated glass.Its spectral reflectance was measured by using spectrophotometer. The effects of visual field,colour space and standard illuminant on the calculated value of colour difference of the glass are also analyzed. Furthermore,this paper provides a suitable method to determine the characteristic value of colour difference for coated glass sample.
