The formation of quartz window sheet is caused by the high temperature viscosity of its melt. It is widely used in the manufacture of semiconductors, electro-optical sources, semi-conductive communication devices, lasers, optical instruments, laboratory instruments, electrical equipment, medical equipment, and high-temperature and corrosion-resistant chemical instruments, chemical, electronic, metallurgical, building materials, and national defense industries. The optical performance of quartz window sheet has its own uniqueness. It can not only transmit far ultraviolet light, but also transmit visible light and near-infrared spectrum. Because quartz glass has high temperature resistance, small coefficient of thermal expansion, good chemical stability, and bubbles, stripes, uniformity, and birefringence comparable to ordinary optical glass, it is an essential optical material with high stability optical coefficient in various harsh conditions. It can be divided into three categories according to its optical properties:
1. Far ultraviolet optical quartz glass JGS1
Transparent in the range of ultraviolet and visible spectrum; There is no absorption band in the range of 185-250nm; There are strong absorption bands in the range of 2600-2800nm; Non-luminescent, stable light radiation.
2. Ultraviolet optical quartz glass JGS2
Transparent in the range of ultraviolet and visible spectrum; There is no absorption band in the range of 200-250nm; There are strong absorption bands in the range of 2600-2800nm; Non-luminescent, stable light radiation.
3. Infrared optical quartz glass JGS3
Transparent in visible and infrared spectral range; There is no obvious absorption band in the range of 2600-2800nm.
High-temperature quartz window sheet is a special industrial technology glass made of silica. It is a very good basic material.
