Beam Expanders

Pre-Engineered Beam Expander: Don’t have a complete design? No problem!

Our Pre-Engineered lenses give our customers the option of choosing suitable designs and/or creating their own beam expanders from a variety of our existing lenses based on their applications. Just tell us your application requirements (input beam diameter, wavelength range, magnification, etc.) and our design engineers will optimize our existing designs to meet your exact needs. This will help you cut the product development lead time and also reduce or eliminate design fees! To learn more, please feel free to contact us at +1 732-321-6915 or info@shanghai-optics.com.

Beam Expanders increase the diameter of a collimated laser beam. The entire system does not have a focal length, i.e., both the input beam and output beam are collimated in a beam expander system. For many applications, the input laser beam has spatially varying intensity “noise” and a spatial filter is added into the beam expander system for producing a clean laser beam.

Beam expanders are used in many applications such as laser ranging, laser illumination, interferometry, etc. In high-power laser systems, beam expanders are used increase the beam area without significantly affecting the total laser energy. This results in a reduction of the laser power density which reduce the risk of damaging the coatings and optical materials of optical components. In a laser ranging system, a beam expander is used to minimize the laser divergence, resulting in a smaller collimated beam at a long distance.
