Meller Optics, Inc. introduced custom-fabricated sapphire windows that can withstand extreme pressures and the rigors of harsh subsea applications while providing optimum visibility.
Meller Sapphire Windows are ideal for subsea UAV applications requiring a clear, hard optical material that can withstand high pressures to 10,000 psi and resist saltwater, 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
- Can be made in sizes from 1/4” to 10” dia. and 1/2 mm to 1” thick
- 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
