PROVIDENCE, R.I., May 11, 2011 — For space telescopes and satellites, Meller Optics Inc. custom manufactures sapphire lenses such as the field flattener focusing lenses used in CCD arrays on the Kepler Space Telescope.

Sapphire lenses are manufactured with surface finishes from 60-40 to 40-20 scratch-dig, flatness held to 0.5 fringes of HeNe and parallelism from 20 to 2 arcsec, depending upon the configuration. Selected by NASA for use in the CCD arrays on the Kepler Space Telescope, these sapphire field flattener focusing lenses withstand extreme conditions.

Impervious to water, most acids, alkalis, abrasion from fast-moving particulates, temperatures to 1000 °C and pressures up to 10,000 lb/sq2 in., the lenses can be manufactured in diameter sizes from ? to 4 in. and varying wall thicknesses with ±0.001-in. tolerances in planoconvex, planoconcave, meniscus and dome configurations. Edges can be beveled and polished.
