A wide range of optical domes that can be custom fabricated from sapphire, quartz, glass, silicon, and germanium to protect missile guidance systems are available from Meller Optics, Inc. of Providence, Rhode Island.

Meller Optical Domes offer 160 degrees maximum included angles to protect and extend the viewing angle of missile guidance systems and can be custom fabricated from a variety of materials in sizes up to 100mm dia. with ▒10Ám tolerances.

The sapphire optical domes exhibit Moh 9 surface hardness, can transmit from the UV to the IR, and provide up to 85% transmission uncoated and <0.25% reflection per surface with A/R coatings.
