Alumina Optical Window and Dome
I need an infrared window or seeker dome to an optical specification. Who grows the material and who polishes it?
What it is
Transparent ceramic or single-crystal element that passes infrared or visible light while surviving the outside of an aircraft or missile. Finished by lapping and polishing to an optical figure rather than a dimensional tolerance.
- Typical dimensions
- Fractions of an inch to over a foot across, flat or domed.
- Also known as
- IR window, sensor window, missile dome, sapphire window, optical dome, laser mirror
Suppliers
Grouped by what they actually are. A mill and a distributor answer different needs.

Saint-Gobain Crystals Reported
Sapphire is single-crystal alumina, so this capability also sits on the alumina page. It is a different purchase from sintered polycrystalline alumina.
