Luminosity function correction glass

Abstract

A vision function correcting glass is proportionally prepared from P2O5, sodium oxide, potassium oxide, lithium oxide, aluminium oxide, boron oxide, barium oxide and copper oxide. Its advantages are high cut-off performance to infrared light and high transparency to visual light. It can be used for color brightness meter and chromometer for higher correctness of measurement.

Description

technical field [0001] The invention belongs to an optical glass, in particular to a visual function correction glass. Background technique [0002] The coloring of divalent copper ions in various glass systems has been widely used in the preparation of colored optical glass. It is generally believed that in phosphate-based glasses, due to the pentavalent phosphorus ions on [CuO 6 ] The role and influence of oxygen ions in the coordination, so that [CuO 6 ] to form an uneven structure, resulting in the coloring of divalent copper ions as blue-green. With the development of the instrumentation industry, people have higher and higher requirements for the spectral light transmission of colored optical glass, and the original glass types can no longer meet the needs of development. Contents of the invention [0003] The present invention provides a kind of new visual function correction glass, and its formula is, percentage by weight: [0004] Phosphorus pentoxide 60.0~65....
