Sapphire 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
