Application:
Used with high purity crystal materials and the oxy-hydrogen flames, the crude materials is made, and the quartz ring with SiO2 is more than *9.*9%? the product is transparent, it has no bubbles and other impurities after serious washing and shaping process, its ‘ density is even. The section of the the quartz ring is rectangular, which can be suitable for the long-time vapor deposition of multilayer optical thin film, reaching the first-class quality standard of precise optics. So it is widely used in vapor deposition for AR film and multilayer film which reaches the highest level of precision optical evaporation.
