Anti-reflection coated article
Abstract
A transparent or translucent coated article, comprising an optical substrate and one or more layers of anti-reflection material coated on at least a portion of the optical substrate, characterized in that said one or more layers having a thickness such that the article simultaneously has (i) a color, when viewed at a specified angle or angles, under a specified illumination, that is perceived to lie within a specified volume element of color space defined by the color's CIE chromaticity coordinates, and (ii) a perceived reflectance F=∫∫S(λ,θ)R(λ,θ)dλdθ that is less than or equal to 1.25Fmin, wherein λ is wavelength, θ is incident angle, S(λ,θ) is the human sensitivity function as a function of wavelength and incident angle, R(λ,θ) is an average of p- and s-polarized reflectance, and Fmin is perceived reflectance minimized within the constraints imposed by said chromaticity coordinates.
