Fused Silica Domes
Fused Silica Optical Dome
UV Fused Silica Domes is a good choice in the Solar Instruments. It including
ultraviolet fused silica and infrared fused silica.
For the silica, it has a good transmittance from 180nm to2650nm,
then it is good choice the 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 of high quality deep-sea housings is made fused
silica dome, it have wide-angle and can be protective the deep-sea
Optical dome are lenses with two concentric spherical surfaces. Sometimes they
are being referred to as bent plan parallel plates. Consequently it
is customary to define parallelism between two surfaces as the
maximum thickness variation between the two surfaces.
In perfect domes the convex radius is equal to the sum of the dome
thickness and concave radius, , creating a naturally strong shape
that gets tougher under pressure. This makes dome windows ideal for
underwater environments and in applications such as camera dome
ports and submersible windows.
Fused Silica is outstandingly resistant to water, salt solutions.
Mechanical properties is better than many optical glass:
Compressive strength (approx.): 1150N/mm2
Tensile strength (approx.) : 50N/mm2
Bending strength (approx.): 67N/mm2
