Document Type and Number:
WIPO Patent Application WO/2017/094869
Kind Code:
A1
Abstract:
The present invention relates to a wavelength-selective transparent glass whereof the light transmittance Tgreater than 315 nm, less than or equal to 400 nm at wavelengths from 315 nm exclusive to 400 nm inclusive, represented by the following equation, is 1% or higher when converted into 6 mm plate thickness, and the light transmittance Tless than or equal to 315 nm at 315 nm or shorter wavelengths, represented by the following equation, is 60% or lower when converted into 6 mm plate thickness. (In the equations, Ak s a weighting coefficient at wavelength k (nm) for calculating T (light transmittance) as defined in ISO-9050:2003, and Tk is a transmittance at wavelength k (nm) for calculating the conversion to 6 mm plate thickness.)
