Optical Dome

An optical dome is a hemispherical or spherical transparent cover used to enclose and protect internal optical components such as lenses, sensors, or lasers, while allowing efficient light transmission. It provides physical protection such as dustproofing, waterproofing, scratch resistance, and impact resistance, and safeguards precision optical systems under harsh conditions.

Optical domes are typically made from materials such as fused silica, sapphire, calcium fluoride, magnesium fluoride, zinc sulfide, germanium, and standard optical glass. The choice of material depends on the application scenario and requirements for transmission, mechanical strength, and environmental resistance.

When selecting an appropriate optical dome:

• First, consider the optical wavelength range the dome needs to handle, such as UV, visible, or infrared. Choose materials accordingly.

• Next, account for environmental conditions, such as high/low temperature, underwater, high pressure, or corrosive environments.

• Also consider mechanical properties such as impact resistance, wear resistance, and weight limitations.

We can provide optical domes made from fused silica, sapphire, zinc sulfide, and calcium fluoride.
Available structures include notched domes, domes with flanges, super-hemispherical domes, and hemispherical domes.
We can offer domes with diameters up to 500mm.

Yes, we offer single-band AR, broadband AR coatings covering UV to IR ranges. We can also provide special coatings such as hydrophobic/oleophobic coatings and hard protective coatings.
