Lobster eye optical device channel glass and preparation method thereof

Abstract

The invention provides lobster eye optical device channel glass and a preparation method thereof. The lobster eye optical device channel glass comprises the following components in parts by weight: 60-75 parts of SiO2, 1 to 3 parts of Al2O3, 1.5 to 3 parts of MgO, 5 to 10 parts of Bi2O3, 1.5 to 5 parts of Li2O, 3 to 5 parts of BeO, 8 to 10 parts of Na2O and Cs2O, 3 to 5 parts of SnO2, 3 to 8 partsof ZnO, and 0.5-1 part of Sb2O3. The lobster eye optical device channel glass provided by the invention has the advantages that the requirement of low thermal expansion coefficient of a leather pipeof a lobster eye lens for X-ray detection is met, and compared with the prior art, the MPO optical device channel glass has the advantages that the spherical surface precision is high, and the squarehole precision and the square hole array structure uniformity are better.

Description

technical field [0001] The invention relates to the technical field of lobster eye optical devices (MPO), in particular to leather glass for lobster eye optical devices and a preparation method thereof. . Background technique [0002] The application of lobster eye optics (MPO) in the field of X-ray astronomical observation and imaging requires consideration of the spatial resolution of the MPO lens, and the angular resolution is usually used to characterize the spatial imaging resolution of the lens. The imaging angular resolution is mainly determined by the statistical properties of the micropores, which refer to the structural deformation of millions of square channels inside the MPO after spherical thermoforming. This is the basis for the quality of MPO optical devices and also affects the key performance of optical devices. One of the most important factors of angular resolution. The MPO optical device needs to remove the leather glass and retain the leather glass as ...

AI Technical Summary

Problems solved by technology

Theoretical calculations and actual test results show that the thermal expansion coefficient of MPO optical devices needs to be as low as possible, and the boundary and top angle of the square hole must not be severely distorted, and square hole clogging, air bubbles, and Otherwise, the imaging quality of MPO optical devices will be distorted, which will reduce the focusing performance and affect the realization of scientific goals

And the leather material preparation technology of prior art produces the above-mentioned probability very big, solves very difficult
