Fused Silica Windows

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


Features of fused silica 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 can manufacture high precision fused silica windows by deep optical polishing processing. All of these customized fused silica windows are made of UV-grade or IR-grade synthetic fused silica. In addition, these precise fused silica windows can be coated quality laser anti-reflection coating of high resistance to laser damage threshold. Coated fused silica windows are widely used in high power laser systems as laser head protection windows.

Types of Fused Silica Windows

Creator Optics 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. Like all optical windows, fused silica windows are usually round, rectangular, elliptical, stepped, polygonal, etc.
