PRECISION GRADE OPTICAL WINDOWS

Optical windows are used to separate two different environments while still allowing light to pass through. Advanced Optics manufactures optical windows made of low expansion borosilicate glass and fused silica up to 8" in diameter to meet various demanding applications. Surface flatness of λ/4 and λ/10 are available in low expansion borosilicate glass and λ/10 and λ/20 in fused silica. Custom coatings and sizes are available to meet your requirements as well as free engineering services.

Many of our in-stock optical windows are manufactured from high purity synthetic fused silica. Fused silica provides superior transmission characteristics, a high degree of purity, exceptional environmental durability, and a low coefficient of thermal expansion.
