Paper Abstract

A direct measurement of reflectance spectrum of steeply curved surfaces on commercial spectrophotometer is almost impossible. This work describes the use of colorimetry to estimate the change of spectral reflectance of antireflection coating deposited on such surfaces. The investigations show that the color coordinates for daylight D65 of coatings may be uses for this purpose. The coating deposited on curved surface consists of layers of aluminum oxide, substance H4 highly refractive and magnesium fluoride. Color coordinates for normal CIE'31 observer and illuminant D65 was calculated for varying thickness of layers of the coating. Comparison of calculated on this way color coordinates and observed colors on surface show that method may be used to estimate the reflectance spectrum distribution on the lens surfaces.
