16 Aug 2007 Extremely durable and scratch resistant, DSI’s IsoSphere™ AR coated devices are available in a variety of glass indexes and new, larger sizes from 200 microns up to 10.0 mm diameter. The ball lenses feature transmission values of greater than 99.5 percent in indexes of up to nd 2.0 @550 nm.
Highly suited for telecommunications, datacom and expanded beam connector applications, DSI’s IsoSphere line of ball lens products are an affordable, 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 breakthrough advances in depositing high performance antireflection coatings onto ball lenses make the IsoSphere devices an ideal and inexpensive solution for a variety of telecom and datacom applications. The in-house IsoDyn low pressure chemical vapor deposition (LPCVD) technology at Deposition Sciences permits an exceptionally uniform optical AR coating over the entire surface of the ball lens. This uniformity of the AR coating eliminates the need for orientation of the lens in the customer’s device, greatly reducing labor-intensive, device-assembly costs.
