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

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.

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

Not sure which beam expander will work best in your application? Check out EO's Beam Expander Selection Guide to easily compare each type at Edmund Optics.

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

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

Are standard beam expanders not meeting your application requirements? Learn how to design your own beam expander using stock optics at Edmund Optics.

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.

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.

Axicons are conical-shaped optical components used to create a ring-shaped beam.

Mounting flat mirrors by their edges in a kinematic mount imparts stress onto the mirror surface. This results in distortion and reduced quality of the reflected wavefront, which is especially noticeable when using high-quality mirrors. Stemmed mirrors, on the other hand, are mounted from a smaller diameter “stem” protruding from the back of the mirror, resulting in significantly reduced stress on the mirror surface, high stability, and cost reduction and can be used as a replacement for a more expensive and complex kinematic mount and a conventional mirror.

Single-Material Aspheric Achromats correct chromatic aberrations with a unique geometry, leading to numerous benefits over conventional achromatic lenses.
