Characteristics of Optical Glass

Mar. 17, 2020

Optical glass is used to make glass, lens, prism, reflector, window, etc. of optical instrument or mechanical system. Including colorless optical glass (usually referred to as optical glass), colored optical glass, radiation-resistant optical glass, radiation-proof glass, and optical quartz glass.

Optical glass can change the direction of light propagation, and can change the relative spectral distribution of ultraviolet, visible or infrared light. Narrow optical glass refers to colorless optical glass; broadly defined optical glass also includes colored optical glass, laser glass, quartz optical glass, radiation-resistant glass, ultraviolet and infrared optical glass, fiber optic glass, acousto-optic glass, magneto-optical glass, and light discoloration glass. Optical glass can be used to make lenses, prisms, mirrors and windows in optical instruments. Components made of optical glass are key components in optical instruments.

Hemisphere optical glass dome supplier believes that optical glass is divided into colored optical glass and colorless optical glass.

Colored optical glass is divided into phosphate glass and silicate glass. Neutral (dark) glass ion-selective selective absorption glass with selenium-cadmium colored and ion-colored custom optical glass domean inorganic glassy material that transmits light by refraction, reflection, or transmission, or changes the intensity or spectral distribution of light by absorption. It has stable optical properties and high optical uniformity.

Optical quartz glass window can withstand high temperature and high pressure, mainly used in: special light sources, optical instruments, optoelectronics, military industry, metallurgy, semiconductors, optical communications and other fields. It can test temperature: 1200 degrees, softening temperature: 1730 degrees, the specific parameters are as follows.

Custom Optical Glass Dome

1.JGS1 (far ultraviolet optical quartz glass)

It is an optical quartz glass melted with high purity hydrogen and oxygen. It has excellent UV transmission performance, especially in the short-wave UV region. Its transmission performance is far better than all other glasses. Its transmission at 185mμ can reach 90%.

2.JGS2 (ultraviolet optical quartz glass)

It is an optical quartz glass melted with hydrogen and oxygen. It is a good material in the 220-2500mμ band.

3.JGS3: (Infrared quartz glass)

It is an optical material with high infrared transmission performance, transmission rate up to more than 85%, and its application wavelength range is 260-3500mμ.
