Abstract

The invention discloses surface glass used for preparing an optical fiber faceplate, relates to the field of optical fibers, and overcomes a problem that sealing between an optical fiber faceplate and other parts is bad. Raw materials of the surface glass comprise 45-75% by mass of silica, 1-15% by mass of calcium oxide, 1-18% by mass of boric oxide, 0.1-2% by mass of magnesium fluoride, 1-14% by mass of aluminum oxide, 0.1-2% by mass of bismuth oxide and 0.1-4% by mass of barium oxide. The optical fiber faceplate prepared from the surface glass is high in cathode sensitivity, compatible with photocathode materials and capable of resisting thermal shock and mechanical vibration, and is advantageous in that sealing between the optical fiber faceplate and other parts is good.

Description

technical field [0001] The invention relates to the technical field of optical fibers, in particular to a leather glass used for preparing optical fiber panels. Background technique [0002] Optical fiber is a light transmission tool, and optical fiber panel is an image transmission element formed by a large number of dense optical fibers arranged in an orderly manner and then heated and fused. The optical fiber panel has the characteristics of high light transmission efficiency, small inter-stage coupling loss, clear and real image transmission, and zero thickness optically. The most typical application is as the optical input and output windows of low-light image intensifiers, which play an important role in improving the quality of imaging devices. It is also used in various cathode ray tubes, camera tubes, CCD couplings and other instruments and equipment that need to transmit images, and is widely used in national defense, public security, aerospace, medical and scient...
