A laser beam expander changes beam diameter and divergence using a transmissive multi-element optical system. Expansion and collimation reduce far-field divergence; combined with a focusing lens, it provides a smaller focal spot and higher energy density for laser marking, cutting, welding, and research. The series supports355/532/1064/10600nm and expansion factors of2~5. Compact construction and easy mounting suit mainstream laser equipment. Some standard versions are stocked, and other parameters can be customized.
