WebFor reducing the lead time, you can build your own beam expanders to meet application requirements by selecting different sets of our standard collimating or focusing lenses. Using our standard collimating / focusing lenses, the beam expander can be designed to have magnification up to 10 times for the wavelength of 405nm, 543nm, 633nm, 780nm ... WebBeam expanders are optical systems for increasing or decreasing the diameter of a laser beam. A beam expander can enlarge an input beam by the factor M, but it can also reduce it by the factor 1/M with a reversed optical beam path. Usually beam expanders are used to increase the diameter of laser beams.
