JGS Quartz Glass

JGS quartz glass is a high-purity silica glass known for its exceptional optical clarity, thermal stability, and chemical resistance. Available in grades JGS1, JGS2, and JGS3, it is widely used in applications such as photolithography, laser optics, and infrared devices. With excellent UV transmission and the ability to withstand high temperatures, JGS quartz glass is ideal for demanding environments in industries like telecommunications, semiconductor manufacturing, and scientific research. Its unique properties make it a preferred choice for high-performance optical components.

Excellent UV transmittance: UV transmittance of over 90% at 185nm wavelength is particularly suitable for applications requiring high UV utilization, such as lithography and UV spectral analysis
High thermal stability: it can withstand temperatures up to 1100°C without deformation, and its coefficient of thermal expansion is very small, suitable for use in environments with drastic temperature changes
Chemical purity: The material has good chemical stability and low impurity content, which effectively reduces the risk of contamination in sensitive applications such as semiconductor manufacturing
Low mechanical damping: The mechanical damping properties make it excellent in optical applications, allowing for sharper imaging and more accurate measurements
Wide range of optical applications: Suitable for various optical components such as lenses, Windows, prisms and mirrors, it is widely used for its excellent transmission properties in the visible and ultraviolet ranges

JGS quartz glass is a specialized type of optical glass made primarily from silica, known for its excellent physical and chemical properties. It includes several grades, notably JGS1, JGS2, and JGS3, each suited for different applications. Here’s an overview of JGS quartz glass:

Key Characteristics:
