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.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . 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 Na 2 O equivalent in μg per g glass determined according to ISO 719 of not more than 250 μg/g.
2 . The glass of claim 1 , wherein the glass has at least one of:
a transmission of at least 60% at 200 nm, measured at a thickness of 1 mm; a transmission of at least 85% at wavelengths of at least one of 260 nm, 280 nm or 310 nm, measured at a thickness of 1 mm; a wave front deviation, peak to valley, of less than +0.1 mm; or a refractive index (n d ) of from 1.450 to 1.580.
3 . The glass of claim 1 , wherein the glass has a total content of one or more UV-blocking impurities that is below 10 ppm.
