Choosing the Right Beam Expander with Dr. Mary Turner

Beam expanders are critical components in many laser systems for increasing the diameter of a beam, minimizing divergence, reducing power density, and allowing the beam to be focused to a smaller spot. Learn how to choose the right beam expander for your laser system in this tutorial from Dr. Mary Turner, Technical Fellow at Edmund Optics.

Edmund Optics designs and manufactures a wide variety of beam expanders and other laser optics like mirrors, lenses, crystals, filters, prisms, and more.
