Santa Rosa, CA (PressExposure) February 03, 2011 -- Deposition Sciences, Inc. (DSI), manufacturer of highly durable thin film optical coatings, offers highly durable, evenly-coated anti-reflection ball lenses in diameters from 200 microns up to 10.0 mm. DSI's IsoSphere® AR Coated Ball Lenses are created using the company's proprietary IsoDyn low pressure chemical vapor deposition (LPCVD) process, which provides an ultra-uniform coating over the entire surface of the sphere.
DSI's multilayer coating capability provides dual and broad band AR coatings (e.g. 1310/1550 dual band). The dual band coatings allow one lens to be used for either wavelength, reducing the need for lens inventories. The IsoSphere AR coated ball lenses reduce device assembly costs because there is no need for orientation of the lens in a device since the coating is uniform over all. A wide choice of lens materials, with indices from 1.44 to 2.15 (at 1550 nm), also helps minimize costs while permitting maximum freedom in the optical design.
Featuring hard, scratch resistant coatings (passes 20 eraser rubs), DSI's AR ball lenses are bondable by a wide variety of methods making them ideal for use in new or existing optical designs. They offer an affordable and a mechanically-simple optical solution for coupling and collimating applications, e.g. the output of an optical fiber or laser diode. They are also ideal for fiber-to-fiber, diode-to-fiber, and fiber-to-detector coupling when access to the beam is required.
