PROVIDENCE, R.I., 15 July 2010. Meller Optics Inc. in Providence, R.I., is introducing custom fabricated thin sapphire optics for lightweight aerospace cameras, weapons systems, and viewports in process environments.
Meller sapphire optics can be manufactured to specification from 0.5 millimeter to 1 inch thick, with flatness to within 1/10th wave at 6328 nanometers for the ultraviolet–visible-near infrared (UV-VIS-NIR) light spectra.
More durable than quartz or zinc selenide and offering chemical resistance superior to calcium fluoride and magnesium fluoride, sapphire optics are harsh-environment lightweight applications in the presence of fast-moving dirt and sand.
Second to diamond in hardness and capable of withstanding 1000 degrees Celsius, Meller sapphire optics are available in sizes from 1/4 inch to 10-inch diameter with finishes from 60-40 to 40-20 scratch-dig, depending upon size and configuration.
Windows, lenses, and viewports can be fabricated with slots, wedges, edge treatments including elliptical edge shaping, holes, and A/R coatings. For more information contact Meller Optics online at www.melleroptics.com.
