From this we are about to clarify:
(1) thin-film devices, transmittance, reflectance spectra and the color of the corresponding relationship between, that is, a spectrum of a color; on the contrary, this relationship is “not unique”, manifested as a color multi-spectrum. Therefore, the film’s transmittance, reflectance spectral characteristics and color characteristics need to be characterized separately, not replace each other.
(2) The use of interference films to achieve decorative color applications need to clarify the conversion relationship between color and spectrum.
(3) The characterization of film color needs to be scientific, standardized, unified standardization method.
3. The expression of film color characteristics is based on the national standard GBT3977-2008.
Synthetic
National standards: the basic basis for the expression of color is CIE1931 and CIE1964 standard chromaticity system.
