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.
