Description

Quartz Window Quartz Optical Window
Quartz glass window is a special industrial technology glass made of silica. It is a very excellent basic material. Quartz glass sheet has a series of excellent physical and chemical properties. Quartz glass has good light transmission performance in the whole spectral band from ultraviolet to near-infrared. At the same time, it also has excellent properties and characteristics such as high-temperature resistance, corrosion resistance, high hardness, and low coefficient of thermal expansion. It is often used in semiconductor devices, electro-optic sources, lasers, optical instruments, and so on.

The optical properties of quartz optical windows are unique. It can not only pass through far-ultraviolet light, which is good for all UV transparent materials but also pass through visible light and near-infrared spectrum. Because quartz glass has high-temperature resistance, a very small coefficient of thermal expansion, good chemical stability, and bubbles, stripes, uniformity, and birefringence can be comparable with general optical glass, it is an essential optical material with high stability optical coefficient for working in various harsh occasions.

1. Far ultraviolet optical quartz JGS1
Transparent in the range of ultraviolet and visible spectra; There is no absorption band in the range of 185-250nm; There is a strong absorption band in the range of 2600-2800nm; Nonluminous, stable light radiation.

2. UV optical quartz glass JGS2
Transparent in the range of ultraviolet and visible spectra; There is no absorption band in the range of 200-250nm; There is a strong absorption band in the range of 2600-2800nm; Non-luminous, stable light radiation.

3. Infrared optical quartz glass JGS3
Transparent in the visible and infrared spectral range; There is no obvious absorption band in the range of 2600-2800nm.

Quartz window is usually cut, polished and polished by quartz ingot, and its silica content can reach more than 99.99%. The hardness is mo type 7, with the characteristics of high-temperature resistance, low coefficient of thermal expansion, good heat shock resistance, and electrical insulation. The visible light transmittance of quartz windows is more than 85%. Quartz glass can be divided into fused quartz glass and synthetic quartz glass. Excellent heat resistance, light transmittance, electrical insulation, and chemical stability.

Due to its various characteristics, quartz glass is one of the indispensable excellent materials in modern technology, atomic energy industry, automation system, semiconductor, metallurgy, chemical industry, communication, laser, optical instrument, laboratory instrument, medical equipment, and national defense.
