MARITIME SAPPHIRE OPTICS WITHSTAND SCRATCHING AND HIGH PRESSURE

A broad range of custom manufactured sapphire lenses, windows, and domes for use in submersibles and other deep water undersea applications have been introduced by Meller Optics, Inc. of Providence, Rhode Island.

Custom manufactured to OEM specifications, they can be supplied as lenses, windows, and domes in sizes from 0.25” to 10” O.D. with varying wall thicknesses and treatments.

Featuring surface finishes that can be held to 10-5 scratch-dig, roughness to less than or equal to 0.3 nm RA, and flatness to 0.5 fringes HeNe, Meller Marine Sapphire Optics can incorporate elliptical edge shaping and steps, holes, and slots for mounting.
