    Beam Expander
     

    Beam Expander

     

    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.
