Abstract: A glass has a transmittance at a wavelength of 220 nm of at least 30% and a transmittance at a wavelength of 200 nm of less than 4.0%, the glass having a total platinum content of less than 3.5 ppm. A device and a sterilizer include a light source configured to output ultraviolet light and a lamp cover covering the light source and including the glass.

Abstract: A glass has a transmission throughout a wavelength range of from 207 nm to 222 nm of at least 60%, measured at a thickness of 1 mm. The glass is a borosilicate glass having a total platinum content of not more than 3.5 ppm, and a hydrolytic resistance characterized by an extracted Na2O equivalent in μg per g glass determined according to ISO 719 of not more than 250 μg/g.
