Laser Beam Expander with Diopter Movement 500-700nm 18.5X

BE-18.5-V

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).

Guide
  • We provide the laser beam expander holders (KLH-BE) for optical axis adjustment of the laser beam expander.
  • WEB Reference Catalog Code/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.
  • WEB Reference Catalog Code/W3200
Remark -
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.
