1. Introduction
Variable Beam Expanders are ideal for the systems where different magnifications and precise control of laser
beam divergence/focusing is required. Standard Variable Laser Beam Expander models with expansion rates of
1X-4X will be reviewed in this manual. The beam expander incorporates zooming and focusing compensation,
which is realized by rotating external parts of the beam expander. There are two set screws to lock magnification
and focusing position once desired beam size is reached.
