Product description:
JGS1 quartz plate; Quartz plate
Zs-1 (far ultraviolet quartz glass) corresponds to brand JGS1
It is with high purity hydrogen fusion of optical quartz glass, so contains a lot of hydroxyl (2000 PPM), it has excellent through ultraviolet performance, especially in the shortwave ultraviolet region, its performance is better than all the other at a distance through glass, at 185 microns of transmittance can reach 90%, synthetic quartz glass has a strong absorption peak at 2730 nm, no granular structure. It is an excellent optical material in the range of 185-2500m.
Transmission spectrum at 1.0mm thick:
JGS2 quartz plate; Quartz plate
Zs-2 (ultraviolet quartz glass) corresponds to brand JGS2
Quartz material and hydrogen-oxygen flame produced quartz glass, containing several PPM of metal impurities. The absorption peak (hydroxyl content 100-200ppm) was found at 2730nm, with striations and granular structure. It is a good material through the 220-2500 m band range.
Quartz characteristics:
Quartz glass sheet is a special industrial glass made of silica, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties, such as: 1, high temperature resistance. The softening point temperature of quartz glass is about 1730℃, which can be used for a long time at 1100℃, and the maximum operating temperature can reach 1450℃ in a short time. 2. Corrosion resistance. In addition to hydrofluoric acid, quartz glass and other acid substances almost no chemical reaction, its acid resistance is ceramic 30 times, stainless steel 150 times, especially in the high temperature chemical stability, is any other engineering materials are incomparable. 3. Good thermal stability. Adapt to the glass thermal expansion coefficient is very small, can withstand drastic temperature changes, quartz glass heated to about 1100℃, put in room temperature water will not burst. 4. Good light transmission performance. Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The visible light transmittance is more than 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach more than 80. 5, the electrical insulation performance of quartz glass is good. The resistance value of quartz glass is equivalent to ordinary glass 10,000 times, is an excellent electrical insulation material, even at room temperature also has good electrical performance.
