The TECHSPEC® Vega™ Laser Line Beam Expanders from Edmund Optics® are divergence adjustable to compensate for input beam divergence.

Edmund Optics offers both fixed power and zoom beam expanders. Knowing which beam expander is right for your application can greatly improve system efficiency.

Learn how to choose the right beam expander for your laser system in this tutorial from Dr. Mary Turner, Technical Fellow at Edmund Optics

Laser beam expanders are critical for reducing power density, minimizing beam diameter at a distance, and minimizing focused laser spot size.

Laser beam expanders consist of transmissive configurations, with Galilean or Keplerian designs, and reflective configurations, which use a series of mirrors, similar to microscope designs.

Sliding focusing mechanisms for laser beam expanders cause less beam wander than rotating focusing mechanisms, but they use more complex mechanics and are typically more expensive.

LC (Low Cost) Fixed YAG Beam Expanders are simple 2-element, cost-effective solutions to beam expansion.

Monolithic Reflective Beam Expanders are ideal for applications requiring broadband or achromatic beam expansion.

Shack-Hartmann wavefront sensors are used to test the transmitted wavefront error of laser beam expanders, predicting the real-world performance of the beam expander.

Converting a Gaussian laser beam profile into a flat top beam profile can have numerous benefits including minimized wasted energy and increased feature accuracy.

The diameter of a laser highly affects an optic’s laser induced damage (LIDT) as beam diameter directly impacts the probability of laser damage.

Surprisingly, intentionally clipping a laser beam going through a higher magnification beam expander can be the optimal solution.
