PROVIDENCE, R.I.– Meller Optics Inc., has created custom sapphire windows that can withstand extreme pressures and the rigors of harsh subsea applications while providing optimum visibility, Meller said in a press release.
Meller Sapphire Windows are reported to be well-suited for subsea UAV applications requiring a clear, hard optical material that can withstand high pressures to 10,000 psi and resist salt water, chemicals, and fast moving particles. With a Mohs 9 hardness that is second only to diamond, the sapphire windows can be custom manufactured to specification in a wide range of sizes with varying thicknesses, mounting profiles, steps, and edge treatments to assure a reliable fit and seal.
Meller Sapphire Windows can be made in sizes from 1/4-inch to 10-inch diameter and from 1/2mm to 1 inch thick, depending upon configuration, and can include A/R coatings. Other sapphire optics include domes and lenses with focal lengths from 3/4 inch to 1,000 mm or greater, and surface finishes from 60-40 to 40-20 scratch-dig, depending upon size and configuration.
