Optical grade Fused Silica is a high purity synthetic amorphous silicon dioxide which is manufactured by flame hydrolysis.
Some beneficial characteristics indlude very low thermal expansion coefficient, very good homogeneity with excellent optical properties and exceptional transmittance in the UV range.
It has been used widely for Laser optics, optical grade UV Fused Silica windows and lenses, mirror blanks and substrates, wedges, optical beamsplitters and filters, prisms, lightpipes, space and aircraft windows, solar cells, high quality coating substrates etc.
