JGS1, JGS2, JGS3 grades of optical glass. The product is mainly used for optical lenses, high-temperature insulation, optical forming, etc. Optical quartz glass is a high-purity special industrial technology glass containing only silicon dioxide (SiO2) as a single component. Due to its unique properties that cannot be replaced by other materials, including very low thermal conductivity, excellent thermal shock resistance, high deformation and softening temperatures, low thermal conductivity, low dielectric loss, and optical transmittance over a wide spectral range from ultraviolet to infrared. It has played a very important role in modern industry and high-tech fields.
