Lab quartz glass plate widely used in Optical instruments

Long-term use No bubbles, smooth surface Small thermal inertia Good light transmission High purity

Start From AOBO

The quartz plate, usually made of quartz melting and cutting grinding is made, its silica content of up to more than 99.99%. Morse seven hardness, with a high temperature, low coefficient of thermal expansion, thermal shock resistance and good electrical insulation properties and other characteristics. Usually as a colorless transparent class, visible light transmittance of more than 85%.   Its unique optical properties of the quartz plate, either through the far ultraviolet, the best of all through UV material, but also through the visible to near-infrared spectroscopy. Quartz glass, high temperature, low thermal expansion, good chemical stability, bubbles, stripes, uniform birefringence can be comparable with the general optical glass, so it is working under the worst conditions with high stability optical The essential optical material.
