ProductIntroduction:

  

    Beamexpander is an optical device which used to increase the diameter of collimatedinput beam to larger collimated output beam. The Beam expander primarilyapplied in such Laser scanning, laser cutting, interferometry, and remotesensing. Usually, the beam expander consists of a negative and a positive lens.
