Recently, at the 4th China Science and Technology Achievements Trade Fair, SHJZ Optical Materials Technology Corporation brought its breakthrough optical material: synthetic fused high-purity quartz.
The synthetic fused silica exhibited at the site is a piece of quartz with a diameter of 40 cm, a height of 20 cm, and a weight of about 50 kg. Its purity is as high as 99.9999%, and the whole body is crystal clear and belongs to the special class of quartz. According to the design and production technical standards, it has almost no flaws, and it is more crystal clear than pure crystals in the sun. It can be used in high-power lasers, laser fusion, lithography optics, aerospace, deep space exploration, optical waveguides, and optical communications. And other fields.
According to the staff, synthetic fused silica has a uniformity of less than two parts per million compared with other domestically produced quartzes, with a stress distribution of less than 1 nanometer per centimeter, and the overall refractive index of the material has reached the first-class technical standards of top brands.
The hydroxyl content (OH) of synthetic fused silica is less than 30. Such a low content has reached the first-class quality technical standards of international brands, and its refractive index and light transmittance are very high. "Compared with the high quality and high cost of international high-end brands and the low quality and low price of most Chinese quartz materials, SHJZ products have found a balance between high quality and low cost.
At present, SHJZ has realized the mass production and stable supply of high-purity synthetic fused silica. In the future, the company will further increase the technological innovation and scientific research investment of synthetic fused silica materials, and innovate and develop the hydrogenation technology of synthetic fused silica materials to make it better , More in-depth application in the most cutting-edge high-end lithography, high-end chip production and production fields.
