Fused Silica Windows

(UV Fused Silica Windows, IR Fused Silica Windows, Quartz Crystal Windows)


     Optical fused silica is resistant to high temperature and high pressure, and is irreplaceable for other optical materials. It has good UV transmittance performance, visible and near-infrared light absorption rate is very low, is the production of optical window material of choice. The thermal expansion coefficient is very small, the chemical stability is good, the birefringence can be comparable with the ordinary optical glass. Therefore, it is an optical material necessary for high stability optical systems when working in a variety of harsh environments.

     Creator Optics ( CNCO ) is a manufacturer that customizes a variety of fused silica optical windows. The main products are UV fused silica windows, IR fused silica windows and quartz crystal windows. We can provide custom-made fused slica windows according to special requirements or drawings.

     All of these customized fused silica windows are made of UV-grade or IR-grade synthetic fused silica. Creator Optics can manufacture high precision fused silcia windows. The surface quality can up to 10/5, surface accuracy / flatness can up to 1/20 lambda and parallelism up to 30 arc second. In addition, these hi-precision fused silica windows can be coated quality laser AR coating of high resistance to laser damage threshold. Widely used in high-power laser Head Protection window.
