Introduction to the optical function of the quartz glass tube
Have everyone understood the optical function of the quartz glass tube? Today, the editor will show you the optical features of quartz glass tubes!
Quartz glass has particularly good light transmittance over the entire wavelength. In the infrared region (special infrared glass outside), the spectral transmittance scale is larger than that of ordinary glass. In the visible spectrum, the transmittance is up to 93%, and in the ultraviolet spectrum, especially in the short-wave ultraviolet spectrum, the transmittance is much better than other glasses. The optical function of quartz glass depends to a large extent on its chemical purity. Even 0.001% impurities will obviously affect the quality of the product. The content of transition metal impurities will change the wavelength and move to the long-wave direction, and the presence of hydroxyl will absorb the 2.73μm optical band. . There are three trademarks for domestic optical quartz glass: JGS1 extreme ultraviolet optical quartz glass, using wave band 185-2500μm, made of composition quartz, SiCl4 as material; JGS2 ultraviolet optical quartz glass, using wave band 220-2500μm, using crystal as material, gas refining method Produced; JGS3 infrared optical quartz glass, using the wave band 260-3500μm, using crystal or high-purity quartz sand as the material, produced in a vacuum pressurized furnace. Quartz glass tube.
