Jenoptik - Variable Beam Expander
Beam expanders increase or decrease the diameter of a laser beam. In doing so, they enable different components of an optical system to adapt to one another. For example, the diameter of the laser beam at the laser exit point can be adapted to the required diameter at the lens entry point. In particular, beam expanders are used in laser material processing. You can integrate all beam expanders into a variety of beam guiding systems with Jenoptik`s F-theta objective lenses.
The beam expanders boast sturdy construction and compact housing. The lens elements do not rotate, even during a set-up change. That makes for particularly high beam stability. Moreover, the beam expanders are diffraction-limited: The diameter of the laser beam is limited only by the diffraction of the incident light. A zoom and focus scale is engraved on the beam expander, enabling you to make quick and easy adjustments by hand.
