PROVIDENCE, R.I., Oct. 21, 2010 — Meller Optics Inc. has introduced sapphire and spinel optical domes that provide front surface protection to electronic sensors and detectors in harsh aerospace and industrial environments.

They feature 160° maximum included angles to extend the viewing angles of cameras, sensors, detectors and other devices and provide extreme physical protection in harsh environments. Able to withstand moving sand, dirt, water and chemicals, they can be custom engineered with precise edge steps and profiles for mounting purposes.

Providing up to 85% transmission uncoated in the ultraviolet to infrared, with up to 99% when antireflection-coated on two sides, the optical domes exhibit Moh 9 hardness (second only to diamond) and can be supplied with outer diameter sizes of up to 101.6 mm, with surface finishes to 20-10 scratch-dig. Optical domes can also be made in outer diameter sizes up to 152.4 mm from spinel, which exhibits Moh 8 hardness.

They are priced depending upon material, configuration and quantity. Price quotations are available upon request.
