Edmund Optics    Barrington, NJ 08007
Jun 06, 2014 Available in 1X–3X or 2X–8X magnification ranges for 532 or 1,064 nm or broadband visible wavelengths, TECHSPEC® Variable Beam Expanders offer continuous magnification for laser applications where magnification changes may be required. Galilean designs feature 1/4 λ transmitted wavefront, and AR coatings ensure maximum transmittance while minimizing ghost reflections. Non-rotating internal translation and focusing mechanisms continuously adjust magnification and laser divergence.

Lumetrics, Inc.    Rochester, NY 14623
Apr 09, 2013 Beam expanders and reducers are available to enhance capabilities of Shack-Hartmann Complete Light Analysis System (CLAS-2D) wavefront aberrometers, which operate with light sources from 193–1,700 nm. Standard expanders and reducers allow beam measurement up to 60 mm, but larger, custom beam reducers can also be designed. Uses include wind tunnel turbulence applications, wind shear testing, beam analysis, large mirror surface topology, and complex alignment/analysis applications.

Laser Beam Combiners meet laboratory and industrial needs.

Edmund Optics    Barrington, NJ 08007
Oct 14, 2009 Designed to combine or separate multiple laser beams between 375 and 785 nm at 45° angle of incidence, Dichroic Laser Beam Combiners feature greater than 98% reflection and 95% transmission. Polarization-insensitive products, available at 6 cut-off wavelengths, are constructed from low-autofluorescence substrates with dense, durable coatings and feature Hard Ion-Beam Sputtered Coating. Applications include multi-laser fluorescence imaging and measurement.

Edmund Optics    Barrington, NJ 08007
Jun 29, 2009 Zoom Beam Expanders are designed for Nd: YAG laser sources, providing variable magnification of 1-3x and 2-8x with adjustable focus to correct for laser beam divergence. Antireflective coating can be customized for various wavelengths. Devices are available for 1,064 nm lasers in both 1-3x and 2-8x models, with Output Clear Apertures of 20, 30, 38, and 60 mm; and in 532 nm models with magnification of 1-3x with aperture of 20 mm and, as with 355 nm models, 2-8x with apertures of 30 and 60 mm.

Beam Expander includes diffraction limited optical designs.

Special Optics, Inc.    Wharton, NJ 07885
Apr 23, 2008 Featuring large output clear apertures of 10-100 mm, expansion ratios from 5x to 40x, and input apertures of 1.3-20 mm, laser beam expanders provide adjustable focus for collimation at varying wavelengths, which can be used for divergence correction, collimation, and focusing. With damage thresholds of 500 MW/cm² typical, they can be specified at single and dual wavelengths from 248-1,550 nm. Rugged and self-supporting units have aluminum construction to minimize thermal distortion.
