The optical performance of the fused quartz plate has unique features. It can not only pass through far ultraviolet rays, which is the best among all ultraviolet-transmitting materials but also pass through visible light and near-infrared spectrum. Due to high-temperature resistance, extremely small thermal expansion coefficient, good chemical stability, and bubbles, stripes, uniformity, and birefringence, fused quartz plate is comparable to ordinary optical glass, so it works in various harsh situations with high stability optical coefficients. Essential optical material. Next, let's take a look at the optical and physical properties of the fused quartz plate.
Here is the content list:
According to the optical performance of fused quartz plates, they can be divided into three categories.
The physical properties of fused quartz plate.
Transparent in the UV and visible spectral range. There's no immersion band in the range of 185- 250nm. There's a strong immersion band in the range of 2600- 2800nm. Non-luminous, stable light radiation.
Transparent in the ultraviolet and visible spectral range; no immersion band in the 200- 250nm band. There's a strong immersion band in the range of 2600- 2800nm. Non-luminous, stable light radiation.
Transparent in the visible and infrared spectral range. There is no obvious absorption band in the range of 2600-2800nm. Compared with ordinary silicate glass, transparent fused quartz plate has excellent transmission performance in the whole wavelength head. The spectral transmission in the infrared region is larger than that of ordinary glass. In the visible region, the transmittance of quartz glass is fairly high. In the ultraviolet spectrum region, especially in the short-swell ultraviolet region, the spectral transmission is much better than in other specs. Spectral transmittance is affected by three factors reflection, scattering, and absorption. The reflection of the fused quartz plate is generally 8, the ultraviolet region is larger, and the infrared region is lower. therefore, the transmittance of quartz glass is generally not further than 92. The scattering of quartz glass is fairly small and can generally be ignored. Spectral absorption is nearly related to the impurity content of quartz glass and the production process. The position of transmittance in the band below 200 nanometers represents the number of substance impurities. The uptake at 240 nm indicates how important an anoxic structure there is. The absorption in the visible band is due to the presence of transition substance ions, and the absorption at 2730 nanometers is the absorption peak of hydroxyl, which can be used to calculate the hydroxyl content.
fused quartz plate is a special artificial specialized glass made of silica, which is a veritably good introductory material. fused quartz plate has a series of excellent physical and chemical parcels, similar as:
The fused quartz plate is resistant to high temperatures. The softening point temperature of quartz glass is about 1730°C, and it can be used for a long time at 1100°C, and the highest service temperature can reach 1450°C for a short time.
fused quartz plate is corrosion resistant. In addition to hydrofluoric acid, quartz glass hardly reacts with other acids, and its acid resistance is 30 times that of ceramics and 150 times that of stainless steel, especially its chemical stability at high temperatures, which cannot be achieved by any other engineering materials.
fused quartz plate has good thermal stability. The thermal expansion measure of the adaptable glass is extremely small, and it can repel severe temperature changes. When the quartz glass is at a toast to about 1100 °C, it will not burst when placed in room-temperature water.
fused quartz plate has good light transmission performance. fused quartz plate has excellent light transmission performance in the entire spectral band from ultraviolet to infrared, and the visible light transmittance is above 93, especially in the ultraviolet spectral region, the maximum transmittance can reach further than 80.
