This is an optical system for expanding a small collimated laser beam to a larger one. Fine adjustment of the collimator is available using the diopter correction function. You can use in a high precision optical system like an interferometer or laser processing with lens designed for wave from aberration.

◦The beam expander optical system is air-space with no bonded lenses and can be used for high powered laser applications.
◦With the Galilean type lens configuration, it reduces the number of aberration corrections and shortens the length of the beam expander.
◦By turning the diopter ring on the beam expander, you can have a varied collimated beam with beam divergence on the focused beam. A beam waist or an accurate adjustment of the collimation is required.
◦There is a wide variety with different magnification and wavelengths to choose from.
◦With the different types of BE-V and LBED visible lasers, can be attached to a He-Ne (05-LHP) lasers with an adapter (included).

▶We provide the laser beam expander holders (KLH-BE) for optical axis adjustment of the laser beam expander.
W4147
▶We can also fabricate achromatic beam expanders with multiple wave lengths other than those found in on-line and in our catalog, call our Sales Division for more information.
▶Fabrication of beam expander for high-energy pulsed laser is also available.
W3200

Attention

▶By using in the opposite direction, it will not create a reduction in diameter of the collimated beam. Please use the appropriate optical system by determining the position of the beam waist and the divergence angle of the laser beam.

Lens configuration
■Beam expander is divided into two main types depending on the configuration of the lens.

Diopter and diopter correction function

By using the diopter correction function, it is available to adjust the divergent light beam to the parallel beam. If it is necessary to use exact optical laser system, recommended to use the beam expander with diopter correction function. And if the parallel light beam incident into the beam expander, the light would be emitted in expanded beam.
However, since most laser is slightly divergent, the beam will not be emitted by parallel beam. In addition, parallel light emitted from the beam expander will be shifted in various factors.
Such as LD (laser diode) which has a possibility that wavelength will change, and by the changes of the temperature.
