Meller Optics offers custom fabricated sapphire windows for UAVs exposed to chemicals, gases, particulates, and pollutants that can cause damage to sensitive vision systems. The windows provide optimum optical clarity and feature Mohs 9 hardness to protect drone vision systems in harsh environments where they may be exposed to chemicals, fast moving particles, gases, and high heat. Custom fabricated in sizes from 1/4” to 10” dia. and 1/2 mm to 1” thick, depending upon configuration, they can also include A/R coatings.
Fabricated with a flatness held to 0.5 fringes of HeNe and parallelism from 20 to 2 arc/s, surface finishes are available from 60-40 to 40-20 scratch-dig. Additionally, the windows can withstand temperatures to 1,000°C and pressures to 10,000 psi, depending upon configuration. Other sapphire optics include domes and lenses with focal lengths from 3/4” to 1,000 mm or greater. For more, visit Meller Optics, call 800-821-0180, and/or e-mail: [email protected].
