Improvement of Calculation Accuracy of Dominant Wavelength and excitation Purity for Glass Product

ABSTRACT

This study suggests the accurate method to calculate dominant wavelength and excitation purity which are used for analyzing color of glass product. Instead of ruler and magnified chromatricity diagram by using the slope of lines by tristimulus measured and achromatic timulus and by monochromatiic stimulus and achromatic stimulus calculating method of dominant wavelength and excitation purity was acquired with the relation between them. When it was applied to products the obtained results were more accurate than those from existing methods

Key words: Glass, Color, Chromaticity, Dominant wavelength, Excitation purity
