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.

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.

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.
