Abstract
A wavelength-selective transmissive glass has a light transmittance Tat a wavelength of more than 315 nm and 400 nm or less represented by the formula shown below of 1% or more in terms of a plate thickness of 6 mm and a light transmittance Tat a wavelength of 315 nm or less represented by the formula shown below of 60% or less in terms of a plate thickness of 6 mm. Ais a weighting factor at a wavelength k (nm) for calculating T (light transmittance) defined in ISO-9050:2003, and Tis a transmittance at the wavelength k (nm) in terms of a plate thickness of 6 mm:=(Σ)/(Σ)=(Σ)/(Σ).
