These probes collimate the highly divergent outputs of our large size liquid light guides. You can also use them to collimate the output from our fiber bundles, if you require a large diameter collimated beam (we offer dedicated probes for a collimated beam size of <13 mm). We mounted the lenses in three different flange series housings, to easily mate with our standard products. Four nominal beam sizes are offered: 1, 1.5, 2 and 3 inch. All of them accept the 11 mm OD of our Oriel^® Fiber Connectors. The Ordering Information Tables list the typical collimated beam sizes as seen in the “collimation zone” (range of distances from the surface of the lens over which the beam size and intensity distribution will be most stable). Beam size ranges are driven by wavelength and source size dependent properties of the optical design. The half angle divergence is a function of the focal length and source size.
