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. Contact us.
