Request InfoMeller Optics Inc.PROVIDENCE, R.I., June 17, 2011 — Meller Optics Inc. released a full line of miniature precision sapphire and ruby balls suitable for use in medical and chemical pumps as check and metering valves, and as ball and roller bearings, stylus tips and endoscope lenses. Offered in 42-in. and metric sizes from 0.1 mm to 0.5 in. in diameter, the balls feature Moh 9 hardness and a surface finish of 20-10 scratch-dig or better. They can be precision ground into planoconvex lenses, and they can be drilled if required. With a melting point of 2000 °C, the balls are impervious to most chemicals, solvents and detergents.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 8/17/2022CO2 Laser LensesOEM-compatible, field-replacement CO2 laser lenses with specific focal lengths have been announced by Laser Research Optics.
