The company’s custom fabricated sapphire windows can withstand extreme pressures and the rigors of harsh subsea applications while promising optimum visibility. They can withstand pressures to 10,000 psi and resist salt water, chemicals, and fast moving particles. Featuring Mohs 9 hardness, which is second only to diamond, they can be 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. Fabricated with flatness held to 0.5 fringes of HeNe and parallelism from 20 to 2 arc/secs., the windows can be made in sizes from 1/4” to 10” dia. and 1/2 mm to 1” thick, depending upon configuration and can include A/R coatings. Other sapphire optics include domes and lenses with focal lengths from 3/4” to 1,000 mm or greater and surface finishes from 60-40 to 40-20 scratch-dig, depending upon size and configuration.
