Custom engineered sapphire optical domes that are ideal for subsea drone applications to extend the viewing angle of vision systems and resist algae growth are available.
Meller Sapphire Optical Domes are ideal for deepwater UAVs and other subsea applications to extend the viewing angle of cameras by up to 160-deg. and can withstand pressures to 10,000 psi, depending upon configuration. Featuring Mohs 9 hardness which is second only to diamond, these optically clear domes resist fast moving sand, salt water and most chemicals, and provide a smooth surface which helps prevent algae growth.
Exhibiting up to 85% transmission uncoated in the UV to IR, with up to 99% when A/R coated on two sides, Meller Sapphire Optical Domes can be made in sizes up to 10” O.D. with varying wall thicknesses and precise edge steps and mounting profiles, where required. Surface accuracy is to < 1 fringe @ 633 nm and finishes are to 20-10 scratch-dig per MIL-PRF-13830.
