摘要： A wavelength-selective transmissive glass has a light transmittance Tmore than 315 nm and 400 nm or less at 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 T315 nm or less at 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. Ak is a weighting factor at a wavelength k (nm) for calculating T (light transmittance) defined in ISO-9050:2003, and Tk is a transmittance at the wavelength k (nm) in terms of a plate thickness of 6 mm: Tmore than 315 nm and 400 nm or less=(Σk=more than 315400 Ak×Tk)/(Σk=more than 315400 Ak) T315 nm or less=(Σk=300315 Ak×Tk)/(Σk=300315 Ak).
