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.
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
