2.Features of quartz glass
●Light transmittance: High transmittance over a wide range of wavelengths from ultraviolet to infrared. In particular, it shows good transmission characteristics in the short wavelength ultraviolet region.
●High purity: Very high purity. Therefore, the contained impurities are very small. Ideal for semiconductor and liquid crystal manufacturing processes that dislike alkali and other impurities.
●Heat resistance: Combines excellent heat resistance and thermal shock resistance with a low coefficient of thermal expansion. Another feature is that the thermal conductivity and specific heat are extremely small. Chemical resistance It is extremely chemically stable and has excellent chemical resistance.
3.Types of quartz glass
〇Synthetic quartz glass
Daico's synthetic quartz glass is a high-quality optical synthetic quartz glass that has ultra-high purity and high homogeneity, and exhibits far better transmission characteristics than other glasses, especially in the ultraviolet region.
It is most suitable for optical components (lenses, windows, mirrors, prisms, etc.) for high-power ultraviolet laser equipment such as exposure equipment and excimer lasers.
〇Fused quartz glass
Daico's fused silica glass is ideal for semiconductor and liquid crystal manufacturing processes, lighting sources, and physics and chemistry equipment, taking advantage of its high purity, heat resistance, and electrical insulation properties.
