Beam Expanders

Beam expanders typically are use in systems with a long beam path to keep the beam collimated, or to vary the focus spot size for a given focusing lens. Various magnifications are available, but it is important to ensure theat the input and output beams clear the apertures.

The CO2mpact beam expander 
has a slide and lock focus setting. The normal setting is infinity. It can be changed to fit certain beam parameters. To keep the beam path enclosed the output should be coupled to an adjustable beam tube to maintain an overall fixed length.

  • Focus adjustable beam expanders
