A Beam Expander is any optical system designed to increase the diameter of a Laser beam. In most cases, the term is taken to mean a telescope designed to take a small-diameter collimated beam input beam and produce a larger diameter collimated output beam, thus reducing the divergence of the beam. The beam expander consists of a negative input Lens and a positive objective. The expansion factor is the ratio of the focal length of the two lenses.

Features

Applications

  • Low power loss

  • Good output collimation

  • Able to withstand laser power of more than 1000 W

  • Adjustable divergence angle of 18 to 32 mrad with the variable beam expanders

  • Precision laser machining: capable to provide a high power density focal spot.

  • Laser range finder: capable to provide a highly collimated beam.

  • Combining with a spatial filter, able to modify laser power distribution.
