Edmund Optics

At booth 1721, Edmund Optics will demonstrate its Techspec LC (low cost) fixed beam expanders, which use a simple, two-element Galilean design to provide cost effective, diffraction limited performance at the design input beam diameter of 1-2mm, the exact value dependent on model.  Beam expanders are used to increase the diameter of a collimated input beam to a larger collimated, less divergent output beam and are ideal in applications including laser scanning, laser materials processing, interferometry and remote sensing.

In this demo, users will be able to see that by expanding the beam initially, you decrease divergence, and this allows you to focus the beam tighter after the beam expands. The demo will show the focus spot size of a non-expanded beam, and then the same beam with a 5X beam expander and a 5X smaller spot size.
