Manual Beam Expanders

Laser Beam Expanders, also known as collimators, are optical devices used to collect a collimated beam of light to expand or reduce its size, depending on the orientation used. They are used for reducing power density, minimizing beam diameter, and reducing laser spot size.  Beam expanders are useful in a variety of applications including interferometry, laser scanning, remote sensing, laser machining, laser ranging, high power lasers and more.  We offer both variable (zoom) and fixed laser beam expanders. In this section, find a variety of off the shelf standard beam expanders or ask us about custom OEM beam expanders.
