Focusing and Imaging Beam Probe, Fiber Bundle, Fused Silica

The 77646 Focusing and Imaging Beam Probe focuses the output of our Fused Silica Fiber Bundles. The fiber bundle is placed one focal length from Lens 1, to produce a collimated beam. This collimated beam is focused one focal length from Lens 2 (not included). The working distance is 7 mm less than the focal length of Lens 2. Lens 1 is a 19 mm focal length, F/1.7 fused silica lens, and is included with the probe. Choose lens 2 from the Related Products, based on the image magnification and working distance required. The nominal magnification is defined as the ratio of the focal lengths of Lens 2 to Lens 1. The Imaging Beam probe images the output from Oriel^® Glass Fiber Bundles. It uses a complex lens (Lens 1) to collect the light, and a second lens, Lens 2, to re-image the end of the fiber bundle one focal length away.
