532nm Laser Beam Expander, High Power Magnification Beam Expanders

Overview:

A Laser Beam Expander will increase the input laser beam by a specific expansion power while decreasing the divergence by the same expansion power, resulting in a smaller collimated beam at a large distance. Laser beam expanders can also be used in reverse to reduce beam diameter rather than expanding it.

Star Optic offers Beam Expanders can expand or reduce the diameter of a collimated beam by a factor of 2, 3, 5, 10, or 20. These Galilean beam expanders use a low-aberration, air-spaced design optimized to provide a wavefront error of less than λ/4 (i.e., diffraction-limited performance) and minimize the impact on the M2 value of the expanded beam. An expanded beam can be focused to a narrow diffraction-limited waist, which can be necessary for use with optics or instruments that have narrow input apertures

We can provide either narrowband or broadband AR coatings besides 532nm wavelength for these fixed-magnification laser beam expanders.
