Borosilicate glass, anti-halo input window glass and preparation method thereof

Abstract

The application discloses borosilicate glass, anti-halo input window glass and a preparation method thereof, relates to the field of optical materials, and solves the problem that the sensitivity of the cathode of an anti-halo input window is low because the concentration of the ions which can produce a colour centre or can be reduced in the existing anti-halo input window is high. The componentsof the borosilicate glass comprise variable valence ion components; the variable valence ion components comprise antimony trioxide and at least one of lead oxide, selenium element, palladium element,tellurium element and rhodium element; the total content of the variable valence ion components is 0.2 to 0.45 weight percent. The borosilicate glass provided by the application ensures that a stray light effect of the anti-halo input window is eliminated, and meanwhile, improves the sensitivity of the cathode of the anti-halo input window.

Description

technical field [0001] The present application relates to the field of optical materials, in particular to a borosilicate glass, an anti-halation input window glass and a preparation method thereof. Background technique [0002] Light-transmitting glass with a black glass layer on the surface can be used to eliminate stray light. It can withstand high temperatures up to 600°C, and has a hard surface that can resist scratches from sharp metals, acid, alkali, and chemical solvents. Therefore it can be used as an anti-halation input window. Compared with the input window of the optical fiber panel, the transmittance of the anti-halation input window made of light-transmitting glass is increased by more than 20%, and the sensitivity of the cathode is increased by nearly 20%; it can also be used as an optical lens, which can effectively eliminate the surface and The scattered light generated by internal stripes, bubbles and other defects and the reflected light of the optical pa...
