Meller Optics, Inc., based in Providence, RI, has unveiled custom-engineered sapphire windows designed specifically for aerospace applications, where their remarkable hardness, resilience, adn capacity to endure extreme temperatures are essential.
These sapphire windows boast a Mohs hardness rating of 9, making them the second hardest material after diamond. This remarkable property enables them to resist high-velocity particles, aggressive chemicals, temperatures reaching up to 1,000°C, and pressures as high as 10,000 psi, depending on their specific configuration.
Perfectly suited for aerospace needs, these windows serve as protective front optics in guidance and vision systems, ensuring reliability in critical environments.
meller Sapphire Windows are available in diameters ranging from 1/4” to 10” and thicknesses from 0.5 mm to 1”. they can be customized with anti-reflective (A/R) coatings, stepped edges, elliptical shaping, and also holes, slots, and mounting features. they maintain a flatness tolerance of 0.5 fringes of HeNe and parallelism ranging from 20 to 2 arc seconds, with surface finishes varying from 60-40 to 40-20 scratch-dig.
The pricing for Meller Sapphire Windows is persistent by their configuration, size, and order quantity.Interested parties can request detailed literature and price estimates.
