Collimating Beam Probe, Liquid Light Guide, 40-50 mm, 1.5 Inch Flange

The 76605 Light Guide Collimating Probe collimates the highly divergent outputs of large size liquid light guides. This beam probe can be used to collimate the output from our liquid light guides and fiber bundles with NA between 0.5 and 0.6, a 180 to 2200 nm spectral range, and θ1/2 Divergence Range of 0.95° to 3.5°. The lens is mounted in our standard 1.5 Inch Series housing to easily mate with our standard products. It accepts the 11 mm OD of our Oriel® Fiber Connectors. This probe supports a 21 to 29 mm typical beam size and a 50 to 50 mm collimation zone. 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.
