Chanda quartz products composed of quartz melting and cutting grinding, the silica content can reach more than 99.99%. Hardness is mo type 7, high temperature resistance, low thermal expansion coefficient, heat shock resistance and electrical insulation, etc. Usually colorless, transparent, visible light transmittance over 90%.

Optical properties of quartz plate has its unique feature, it can through the far ultraviolet ray, is all through ultraviolet material best performers, but also through visible light to near infrared spectrum. Because quartz glass high-temperature resistance, small thermal expansion coefficient, good chemical stability, bubbles, stripes, uniformity and birefringence can be rivalled with general optical glass, so it is a job with a high degree of stability in various harsh situation optical coefficient of essential optical material.
