SAPPHIRE WINDOWS PROTECT SENSORS USED IN ROBOTICS

Custom fabricated sapphire lenses that resist scratching, high pressures, and high temperatures typical of environments in which robotics often function have been introduced by Meller Optics, Inc. of Providence, RI.

Meller Sapphire Lenses feature Mohs 9 hardness, which is second only to diamond, and are impervious to water, most acids and chemicals, abrasion caused by fast moving particulates, temperatures to 1,000°C, and pressures to 10,000 psi. Custom fabricated in sizes from 3/8” to 4” dia. and varying wall thicknesses with ±0.001” tolerances, they can be supplied in plano-convex, plano-concave, meniscus, and dome configurations.
