Optical Quartz Windows | High Transparency
Quartz windows are usually made by melting, cutting, and grinding quartz, with a silicon dioxide content of over 99.99%. The hardness is Mohs 7, with characteristics such as high temperature resistance, low coefficient of thermal expansion, good thermal shock resistance, and excellent electrical insulation performance. Quartz windows are usually colorless and transparent, with a visible light transmittance of over 85%.
The optical properties of quartz plates are unique, as they can transmit far ultraviolet light, making them the best among all UV transparent materials, as well as visible and near-infrared spectra. Due to its high temperature resistance, extremely low thermal expansion coefficient, good chemical stability, and comparable bubble, stripe, uniformity, and birefringence to general optical glass, quartz glass is an essential optical material with high stability optical coefficient that works in various harsh environments.
According to its optical performance, it can be divided into three categories:
1. Far ultraviolet optical quartz glass JGS1
Transparent in the ultraviolet and visible spectral ranges; There is no absorption band in the 185-250nm wavelength range; There is a strong absorption band in the 2600-2800nm wavelength range; Non luminous, stable light radiation.
Transparent in the ultraviolet and visible spectral ranges; There is no absorption band in the 185-250nm wavelength range; There is a strong absorption band in the 2600-2800nm wavelength range; Non luminous, stable light radiation.
2. UV optical quartz glass JGS2
Transparent in the ultraviolet and visible spectral ranges; There is no absorption band in the 200-250nm wavelength range; There is a strong absorption band in the 2600-2800nm wavelength range; 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 2600-2800nm wavelength range.
Compared with ordinary silicate glass, transparent quartz glass has excellent transmittance performance across the entire wavelength range. The spectral transmittance in the infrared region is greater than that of ordinary glass; In the visible range, the transmittance of quartz glass is also relatively high. In the ultraviolet spectral region, especially in the short wave ultraviolet region, the spectral transmission is much better than other glasses
