Beam Expander

      Beam Expander is the lens components able to change the laser beam diameter and divergence Angle. From a laser beam process certain divergence Angle,for laser processing, it is only through adjusting to the beam expander laser beam into alignment (parallel) beams, can use focus lens obtain fine small high-resolution density facula.

    Application:
         Laser rangefinder, through the Beam Expander change beam diameter in order to use in different optical instruments ,Beam Expander with spatial filter can make the right symmetrically beam distribution, to become uniform energy distribution.

    Specification:
        Expansion power : 2X ~ 20X
        Coating : A : AR @ 350nm ~ 650nm
                         B : AR @ 650nm ~1050nm
                         C : AR @ 1050nm ~ 1650nm
       The error : < lambda / 10
