Represents the XML element BeamExpander.
Beam Expanders are Lens Systems whose role is to increase the diameter of a collimated input beam to a larger collimated output beam. Beam Expanders typically are afocal systems in which object rays enter and exit parallel to the optical axis. As such a Beam Expander does not have a focal length. In most cases, Beam Expanders are realized as optical telescopes consisting of two lenses. Beam Expanders can be custom built or they are also available as pre-assembled optical devices.
