Custom fabricated sapphire windows that are ideally suited for protecting sensitive vision systems and sensors in hypersonic aircraft and weapon systems have been introduced by Meller Optics, Inc. of Providence, RI.
Meller Flat Sapphire Windows feature Mohs 9 hardness, which is second only to diamond, and can withstand temps. up to 1,000+ C, pressures to 10,000 psi, and are chemically inert, impervious to water, and extremely abrasion resistant. Ideal for protecting vision systems and sensors in hypersonic aircraft and weapon systems, these windows transmit from the UV to IR.
Featuring surface finishes from 60-40 to 40-20 scratch-dig, flatness held to 0.5 fringes of HeNe, and parallelism from 20 to 2 arc/secs., depending upon configuration, Meller Flat Sapphire Windows can incorporate mounting profiles including multiple steps. Manufactured to customer specification, sizes can range from 0.250" to 10" O.D. with varying wall thicknesses.
Meller Sapphire Optics for Drones are priced according to configuration, size, and quantity; manufactured in the USA and Meller is ITAR Registered.
