Fused Silica Dome

Fused Silica Dome

Fused Silica Domes are a good choice in Solar Instruments. It includes ultraviolet fused silica and infrared fused silica.

UV silica has a good transmittance from 180nm to 2650 nm, then it is a good choice for protected UV Radiometers.

For the IR silica, it has broadband transmission from 200nm to 3600nm, it can keep the pyranometer has a wider spectral range, improved directional response, and reduced thermal offsets.

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. 

Primary Applications of Fused Silica Optical Components

Compared to other types of glass, fused silica transmits ultraviolet (UV) light much more effectively, making it a popular choice for lenses and optical components designed for the UV spectrum. Its exceptionally low thermal expansion coefficient also makes it ideal for precision mirror substrates, commonly used in semiconductor manufacturing and laboratory equipment.

Other typical applications include:

Windows and debris shields for crewed spacecraft

High-energy laser vacuum windows

Precision instruments for medical and metrology applications

Photolithography projection masks

First surface mirrors, such as those used in telescopes

Laser windows

Glass wafers for photonic chip manufacturing
