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.

A glass, having a transmission throughout a wavelength range of from 207 nm to 222 nm of at least 60%, measured at a thickness of 1 mm, wherein 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.
A glass article, having a thickness of at least 0.3 mm and being made of a glass having a transmission throughout a wavelength range of from 207 nm to 222 nm of at least 60%, measured at a thickness of 1 mm, wherein 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.
A light-emitting package, comprising:
- an ultraviolet (UV) light source configured to emit UV light;
- and
- a cover surrounding the UV light source and comprising a glass having a transmission throughout a wavelength range of from 207 nm to 222 nm of at least 60%, measured at a thickness of 1 mm, wherein 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.
