Fused silica dome

Fused silica is the amorphous (glassy) state of silicon oxide (quartz, silica). It is a typical glass with a long-range disordered atomic structure. It provides its high service temperature and low coefficient of thermal expansion by cross-linking its three-dimensional structure.UV silica has a good transmittance from 180nm to 2650 nm, then it is a good choice for protected UV Radiometers.And Fused Silica mechanical properties it better than N-BK7, Borosilicate. Some high-quality deep-sea housings are made of fused silica domes, which have wide-angle and can be protective the deep-sea camera

Our Company can provide provide fused silica silica dome with diameters from 5-300mm (accuracy up to 40-20, 1/4L@633nm),coating AR, BBAR, AF or upon request.

Transmission curve

Fused silica is commonly used in applications ranging from ultraviolet (UV) to near-infrared (NIR), and its high transmittance, good heat resistance, and excellent environmental durability make it suitable for use in laser equipment, emission and detection protection equipment, and imaging systems in the ultraviolet spectrum.
