Beam expanders
Laser Beam Expanders can be used over a wide range of narrow wavebands. The units use a Galilean telescope configuration corrected as an afocal system. In addition to expanding a beam, the lens permits users to control the beam`s divergence. The adjustable mount and locking ring permit variable settings of the beam diameter.
