Abstract

The invention provides a jade green optical glass composition which is composed of a basic glass component and a jade green coloring agent, wherein the basic glass comprises the following components in parts by weight: 65-75 parts of SiO2, 4-7 parts of Al2O3, 2-5 parts of CaO, 2-5 parts of PbO, 4-7 parts of BaO and 2-5 parts of ZnO; the jade green coloring agent comprises the following component: Na2SiF6; and the content of the jade green coloring agent in the composition is 3-6 parts by weight. The glass formula is reasonably adjusted, so that the chemical stability of the glass is improved, and the optical glass composition is uniform in coloring, high in devitrification capacity and high in refractive index.

Description

technical field [0001] The invention relates to a jade-colored optical glass composition, which belongs to the field of optical elements. Background technique [0002] Colored optical glass, also known as optical filter glass, is mainly used to make filters for observation, photography, infrared and other instruments to improve the visibility of instruments or meet certain special requirements, and can also be used to make colored glasses. The role of colored optical glass is: it can selectively transmit light of a specific wavelength; it can separate a single spectral line from a discontinuous spectrum; or filter out a certain width of the spectrum from a continuous spectrum or uniformly weaken the spectrum of white light Wait. [0003] The existing jade-colored optical glass composition has insufficient uniform coloring and poor crystallization ability, and cannot meet the needs of users. Contents of the invention [0004] The purpose of the present invention is to ove...
