Beam Expanders,3x, 5x, 10x Options of Expansion Power. A laser beam
expander is designed to increase the diameter of a collimated input
beam to a larger collimated output beam. Beam expanders are used in
applications such as laser scanning, interferometry, and remote
sensing. Contemporary laser beam expander designs are afocal
systems that developed from well-established optical telescope
fundamentals. In such systems, the object rays, located at
infinity, enter parallel to the optical axis of the internal optics
and exit parallel to them as well. This means that there is no
focal length to the entire system.

These Beam Expanders provide an ideal solution for expanding or
reducing beam diameters. Beam expanders are commonly used to reduce
divergence. Another common use is to expand the beam and then focus
with another lens to take advantage of a reduction in spot size.
These beam expanders have all been designed to minimize the
telescope length, minimize the introduced wavefront error
(<λ/4), and provide diffraction-limited performance (for <Ø1
mm input).
