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. |
