Meller Optics, a leading manufacturer of high-quality precision optics for aerospace, defense, medical, and industrial markets, has introduced a full line of sapphire lenses, windows, and other shapes that feature highly precise tolerances for flatness, surface finish, and parallelism.

Meller Sapphire Substrates for Optical Coaters feature 1/10th per wave flatness per inch, surface finishes to 10-5 scratch-dig, and parallelism to 2 arc-sec, per MIL-PRF-13830, depending upon the configuration. Available in sizes from 1/2" to 5" O.D. with ±0.00025" tolerance, substrates can be supplied in unique shapes including pyramids with various modifications.

Featuring plano-convex and –concave, biconvex and –concave, and meniscus, Meller Sapphire Substrates can be plane, wedged, and tapered. Other substrate materials fabricated to specification can include silicon, zinc selenide, zinc sulfide, calcium fluoride, barium fluoride, magnesium fluoride, BK-7, quartz, and common laser glasses.

About Meller Optics

Meller Optics was established as Adolf Meller Company in 1921 located in Providence, Rhode Island to serve the jewelry industry, manufacturing hard crystalline materials such as ruby and sapphire and eventually as jewel bearings to the U.S. Government. The company quickly grew out of its valley street location, and moved to Corliss Street in Providence in 1937, persevering through the economic hardships of the Great Depression. There, it became Meller Optics.
