1, colorless optical glass. The optical constants have specific requirements, with the visible area of high transmittance, no choice of absorption and color characteristics. Abbe number size according to the crown and flint glass, all kings and according to the refraction rate level is divided into several kinds and according to the refraction rate size are arranged in order. Used as a telescope, microscope, camera, lens, prism, mirror, etc..

2, anti radiation optical glass. Larger absorption capacity, high lead glass and CaO-B2O2 system glass on high energy irradiation, the former can prevent the gamma ray and X-ray radiation, which can be slow neutron and thermal neutron absorption, mainly used as the shielding and peeped through the window materials in nuclear industry, medical field, and so on.

3, colored optical glass. Filter glass. Ultraviolet, visible and infrared region specific wavelength selective absorption and permeation, according to the spectral characteristics of points for selective absorption, cut-off and neutral grey 3 class; according to the coloring mechanism are divided into 3 types of coloring ion, metal colloid coloring and selenium and sulfur compounds coloring, mainly for manufacturing filter.

4, optical quartz glass. Using silica as the main ingredient, with characteristics of high temperature resistance, thermal expansion coefficient is low, high mechanical strength, chemical properties good for manufacturing of various bands through the special requirements of the prism, lens, window, mirror, etc..

5, ultraviolet and infrared optical glass. In the ultraviolet or infrared wave band with a specific optical constant and high transmittance, used as ultraviolet, infrared optical instrument or as a window material.

6, radiation resistant optical glass. Under a certain gamma ray and X ray irradiation, the visible area transmission rate is less, and the variety and grade are the same as the colorless optical glass, which is used for the manufacture of optical instruments and peep window under high energy irradiation.
