Sapphire Optical Domes
Meller Optics Inc.Request Info
Meller Optics Inc. has introduced sapphire optical domes for protecting guidance systems, sensors and other devices in harsh airborne and subsea environments.
The domes feature Moh 9 hardness and provide up to 85 percent transmission uncoated in the UV and IR, and up to 99 percent transmission when antireflection-coated on two sides. They can withstand pressure up to 10,000 psi and temperatures up to 1000 °C, and are unaffected by fast-moving dirt, sand, saltwater or chemicals.
Available in sizes up to 6 in. in outside diameter, the domes can incorporate steps and profiles for mounting. They offer 160° maximum included angles to extend the viewing angle of missile-guidance systems, and they exhibit surface accuracy to <1 fringe at 633 nm and finishes to 20-10 scratch-dig per MIL-PRF-13830.
