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.

I am from Cambodia, I have just worked from sand and silica sand, due to the demand from guests in other countries, and Cambodia is rich in mineral resources and sand, so I decided to do this to meet the needs of friendly countries. Please advise if anything is wrong, there will be delays on one thing, if you need sand, silic sand and natural gems, you can contact our company at any time via Email. White silica sand, our company can supply you as needed, with pleasure, cooperation at any time, thank you
