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.
New optical filters are being developed due to the advancements in applications and technologies. Learn more about the future of filters 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.
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.
Rotating vs. Sliding Beam Expander Divergence Adjustment
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.
Converting a Gaussian laser beam profile into a flat top beam profile can have numerous benefits including minimized wasted energy and increased feature accuracy.
