|Custom fabricated sapphire domes for the protection of electro-optical devices including detectors, sensors, and cameras in weapons systems are available from Meller Optics, Inc. of Providence, Rhode Island.
Meller Sapphire Domes feature Moh 9 hardness, which is second only to diamond, and provide 160 degree maximum included angles to extend the viewing angles and protect electro-optics in the front of guided weapons. Providing up to 85% transmission uncoated in the UV to IR, with up to 99% when A/R coated on two sizes, they can withstand very harsh environments.
Unaffected by moving sand, dirt, water, chemicals, and temperatures up to 1,000°C, Meller Sapphire Domes can be manufactured in sizes up to 4” O.D. They can incorporate edge steps and profiles for mounting purposes and can be supplied with surface finishes to 20-10 scratch-dig per MIL-PRF-13830. Spinel domes (Moh 8 hardness) in sizes up to 6” O.D. are also offered.
Meller Sapphire Domes are priced according to configuration and quantity. Price quotations are available upon request.
