OZ Optics offers a complete line of fiber collimators and focusers with low
backreflection, 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 laser diodes, photodiodes, acousto-optic modulators and 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 fiber
packaging of devices.
