Fused quartz from 200nm to 2.2um has high transmittance and low thermal expansion coefficient, which makes it an ideal choice for spherical lens in ultraviolet ray, visible light and near infrared spectrum applications with strict requirements. Spherical lens is commonly used to improve signal coupling between optical fibers, transmitters and detectors, as well as objective lenses in endoscopy and bar code scanning applications. Hemispherical lens simplify the integration of the whole system.
We are leading suppliers of silica sand for various industrial use. We are supplying bulk quantity of silica sand for construction and foundry industrial with Sio2 around 99% and low fe contents ranging from 0.2-0.4%. Our silica sand is also used by glass industries. please contact us for regular supplies of silica sand for various industrial use.
