Beam expanders are useful laser accessories when the beam diameter must be increased. However, their main function is to decrease the divergence of the laser beams which are to be projected over long distances. These precision beam expanders have been designed for use with He-Ne lasers but they can be used for any laser working in the visible part of the spectrum (400 − 700nm).

◦Laser beam expanders designed to use with high powered lasers that are made of lenses attached together without using glue (air-gap).
◦These beam expanders are light weight and short bodied and because they are Galileo type design, they have little aberration and correction.
◦The visible type can be mounted directly to any He-Ne laser.

▶For wavelength or magnification which is not shown on-line or in the catalog, please ask our Sales Division.
▶We provide the laser beam expander holders (KLH-BE) for optical axis adjustment of the laser beam expander.
W4147

Attention

▶Make sure that the beam expander is well aligned with the laser light axis. If the beam expander is inclining, the output light will also be inclined.
▶It is not possible to obtain a decreased beam diameter by using the beam expander on the opposite side. Use it properly to obtain an adequate optical solution.
▶The light may not be collimated when it become divergent or convergent.
