Meller Optics Introduces Sapphire Windows for Drones that Protect Vision Systems When Flying in Harsh Environments

Custom sapphire windows designed for protecting cameras, detectors, and sensors on drones from fast moving dirt and chemicals when flying over harsh environments have been introduced by Meller Optics, Inc.

Meller Optics, Inc. has introduced custom sapphire windows designed for protecting cameras, detectors, and sensors on drones from fast moving dirt and chemicals when flying over harsh environments.


Meller Sapphire Windows for drones combine optical clarity and toughness for protecting sensitive vision systems when flying in harsh environments. Featuring Mohs 9 hardness which is second only to diamond, sapphire resists fast moving dirt, chemicals, high heat and transmits 85% from the UV to IR uncoated and offers better than 99% transmission with A/R coatings.

Featuring Mohs 9 hardness which is second only to diamond, Meller Sapphire Windows for drones combine optical clarity and toughness for protecting sensitive vision systems when flying in harsh environments.

Providing 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., Meller Sapphire Windows for drones are available in sizes from 1/4" to 10" dia. and 1/2 mm to 1" thick. Sapphire can withstand heat up to 1,000°C and pressures to 10,000 psi, depending upon configuration.

Meller Sapphire Windows for drones are priced according to configuration, size, and quantity. Price quotations are available upon request.

New incremental encoder IERF3 L from FAULHABER

FAULHABER is expanding its product range with the ultra-precise incremental encoder IERF3 L. Thanks to the optical measuring principle and state-of-the-art chip technology, the device offers the highest resolution, excellent repeatability, and outstanding signal quality. In typical applications, the positioning accuracy is 0.1° and the repeatability 0.007°. This makes the encoder the perfect solution for high-precision positioning applications in confined spaces.
