OZ Optics collimator/focuser array assemblies assist in developing next generation photonic devices. The arrays are manufactured using precision V-Groove technology in conjunction with a single element lens arrays, enabling sub-micron alignment accuracy. OZ Optics fiber collimators and focusers are designed to collimate or focus light exiting a fiber to a desired beam diameter or spot size. By utilizing diffraction limited lenses, spot sizes of a few microns can be achieved. These devices can be used with Photonic Integrated Circuits (PIC), Arranged Wave Guides (AWG) other fiber optic devices. Collimators and focusers can be used as matched pairs to couple light in and out of optical devices. This makes them ideal for dense fiber packaging devices.
