The IsoSphere AR coated ball lens represents a breakthrough in the technology of ball lenses. Previous coating methods yielded soft, non-uniform single layer AR coatings on ball lenses. DSI's exclusive IsoDyn™ low pressure chemical vapor deposition (LPCVD) process provides a uniform, highly durable high performance AR coating over the entire surface of the lens. IsoSphere ball lenses bring the following benefits:

The IsoSphere AR coated ball lens represents a breakthrough in the technology of ball lenses. Previous coating methods yielded soft, non-uniform single layer AR coatings on ball lenses. DSI's exclusive IsoDyn™ low pressure chemical vapor deposition (LPCVD) process provides a uniform, highly durable high performance AR coating over the entire surface of the lens. IsoSphere ball lenses bring the following benefits:
- Orientation of lens in your device is not required (uniform coating over entire lens surface), reducing device assembly costs
- Multilayer coating capability provides dual and broad band AR coatings (1310/1550 dual band, e.g.); dual band coatings allow one lens to be used for either wavelength, reducing lens inventories
- Wide choice of lens materials with indices from 1.44 to 2.0 at 1550 nm allows maximum freedom of optical design and minimizes cost
- Wide choice of lens size (0.25 mm to 10 mm) allows freedom of optical design; small lens sizes minimize cost
- Hard, scratch resistant coatings (passes 20 eraser rub) Bondable by a wide variety of methods
APPLICATIONS
DSI's IsoSphere ball lenses are an inexpensive, mechanically compact optical method for collimating the output of an optical fiber or laser diode; they can also be used for fiber to fiber, diode to fiber, and fiber to detector coupling when access to the beam is required. Ball lenses are a mechanically simple and economically attractive optical solution to a number of fiber optic coupling and collimating problems.
