IR Fused Quartz Windows & Plates

Infrared grade Quartz windows are made from high purity natural fused Quartz electrically fused. This results in a useful transmission in the infrared from 260nm to 3500nm. The (OH) water content is as low as 5ppm or less. It has a low bubble content with extremely low co-efficient of thermal expansion, outstanding chemical resistance and chemical purity. Widely used in laser applications, low cost infrared windows and useful as a base substrate for IR optical filter coatings.

UQG Optics stock a wide range of sizes and a many options to custom make including surface flatness, coatings, shapes, material and dimensions.
