Post Time:Dec 28,2011Classify:Company NewsView:247

Meller Optics, Inc. has introduced custom fabricated sapphire windows and lenses in sizes up to 10" dia. that transmit from the UV to the IR and are impervious to most chemicals, water, and fast moving dirt and sand. They are clear as glass and nearly tough as diamond, making them ideal for use as protective optics in cameras, weapons, and refractometers, and as machine viewports.

 

Meller Sapphire Optics can be produced in sizes up to 10" dia., depending upon the diameter to thickness aspect ratio, and are impervious to most chemicals, water, and fast moving particles. Featuring transmission from the UV to IR (270 nm to 4.7 microns), these sapphire windows and lenses are clear as glass and second only to diamond in hardness (Moh 9), and can withstand up to 1,000 degreesC.

 

Suitable for use as protective front surface optics and as viewports, Meller Sapphire Optics provide flatness to 1/10th wave in the visible and < 2 arc sec. in./in. parallelism with finishes from 60-40 to 40-20 scratch-dig, depending upon size and construction. Applications for sapphire windows and sapphire lenses include viewing optics in cameras, weapons, and refractometers, and as machine inspection windows.

 

Meller Sapphire Optics are priced according to configuration and quantity. Literature and price quotations are available upon request.
