The optical properties of quartz glass sheets are unique. They can transmit far ultraviolet rays, which is the best of all UV-transmitting materials, and can pass visible light and near-infrared spectrum. Quartz glass is resistant to high temperatures, has a very small thermal expansion coefficient, and good chemical stability. Bubbles, streaks, uniformity, and birefringence are comparable to ordinary optical glass. Therefore, it has high stability optical coefficients for working in a variety of harsh situations Essential optical materials.
According to its optical performance, it can be divided into three categories:
Far ultraviolet class JGS1
Transparent in the ultraviolet and visible spectral ranges; no absorption band in the 185-2500nm band; strong absorption band in the 2600-2800nm band; non-luminous, stable light radiation.
UV class JGS2
Transparent in the ultraviolet and visible spectral range; no absorption band in the 200-2500nm band; strong absorption band in the 2600-2800nm band; non-luminous, stable light radiation.
Infrared class JGS3
Transparent in the visible and infrared spectral ranges; no significant absorption band in the 2600-2800nm band.
