Meller Optics introduces large rugged sapphire windows to protect aircraft electronics in harsh environments

Sapphire windows help protect sensors and cameras from sand and other high-speed particulates on aircraft and weapons flying in harsh environments.

Meller Cropped 13 June 2019
PROVIDENCE, R.I. – Meller Optics Inc. in Providence, R.I., is introducing custom fabricated large sapphire windows to protect electronics in aircraft and unmanned aerial vehicles (UAVs) that fly in bad weather and harsh environments. My SA reports. Continue reading original article

The Military & Aerospace Electronics take:

13 June 2019 -- Meller large sapphire windows can be fabricated in different configurations and sizes to 10 inches in diameter to protect electronics, depending upon the diameter to thickness aspect ratio. Sapphire domes also are available for missiles and weaponry in military applications.

Featuring transmission from the ultraviolet to infrared at wavelengths from 27 nanometers to 4.7 microns, the windows are as clear as glass and protect sensors and cameras from sand and other high-speed particulates.

Exhibiting Mohs 9 hardness which is second only to diamond, Meller large sapphire windows offer flatness to 1/10th wave in the visible and less than 2 arc sec. in/in. parallelism with finishes from 60-40 to 40-20 scratch-dig, depending upon size and construction.
