SANTA ROSA, Calif., Aug. 31, 2006 -- Deposition Sciences Inc. (DSI), manufacturer of highly durable thin-film optical coatings, offers IsoSphere antireflection (AR) -coated ball lenses in a variety of glass indexes and new, larger sizes. Featuring very low insertion loss, the IsoSphere ball lenses are available with AR coatings with transmission values of greater than 99.5 percent in indexes of up to nd 2.0 @ 550 nm.

DSIisosphere.jpgDSI now offers the highly durable, scratch-resistant AR- coated ball lenses in sizes from 200 µm to 10 mm in diameter. Ideal for telecommunications and expanded beam connector applications, DSI's affordable IsoSphere line of ball lens products are a mechanically-compact optical method for collimating the output of an optical fiber or laser diode. Versatile and practical, the IsoSphere AR-coated ball lenses can be used in fiber to fiber, diode to fiber, and/or fiber to detector coupling tasks.

DSI's proprietary IsoDyn low-pressure chemical vapor deposition (LPCVD) technology permits a high performance, uniform optical AR coating over the entire surface of the ball lens. This highly durable, uniform coating eliminates the need for orientation of the lens in the customer's device, thus reducing labor-intensive assembly costs, the company said.

IsoSphere AR-coated ball lenses are extremely stable over temperature and humidity, meeting the severe abrasion, adhesion, humidity and salt fog tests of Mil-C-675 standards. Resistant to most chemicals, DSI's ball lenses are also durably suited for aircraft, oil field exploration and refining, marine, undersea and aerospace applications.

GLOSSARY
diode
A two-electrode device with an anode and a cathode that passes current in only one direction. It may be designed as an electron tube or as a semiconductor device.
lens
A transparent optical component consisting of one or more pieces of optical glass with surfaces so curved (usually spherical) that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object.
