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.

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.

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.
