Jun 24, 2008 TECHSPEC® Broadband Polarizing Cube Beamsplitters split randomly polarized beams into 2 orthogonal, linearly polarized components. Suited for variety of broadband applications, they offer transmission of greater than 90% for P-polarized light and 90° angle of reflection for S-polarized light across entire wavelength range. Beamsplitters are available in sizes of 5, 10, 20, and 25 mm in both VIS (420-680 nm) and NIR (700-1100 nm) versions.

Feb 08, 2008 Optimized for Second Harmonic Generation microscopy, Short-Wave-Pass Dichroic Beamsplitter suits multiphoton fluorescence imaging using femtosecond NIR laser. Filter has low group delay dispersion for minimized pulse broadening to allow deep sample penetration; 100 fs laser pulse broadens by less than 1% after reflection off filter. With controlled polarization dependence, unit maintains linear polarization for reflected laser light and transmitted signal light.

Jun 13, 2007 Made with Ion Beam Sputtering, RazorEdge® Dichroic(TM) Beamsplitters reflect standard laser wavelength incident at 45° while passing broad band of longer Raman-shifted wavelengths. Units guarantee transition from laser line to passband in less than 1% of laser wavelength, regardless of polarization. With dense, hard dielectric optical coating, filters offer high damage threshold and permanent performance, even in harsh, humid environments.

Nov 22, 2006 Designed to work with lasers at variety of wavelengths, Variable Attenuator/Beamsplitter can be used as beamsplitter in holography and precision interferometry applications and as attenuator for general laboratory applications. It divides incident polarized light beam into 2 beams by 90° and intensity ratio of beams can be continuously varied by rotating input half-wave plate. Polarizing beamsplitting cube is built in with 532, 632.8, 800, and 1,064 nm wavelength options.

May 09, 2006 TECH SPEC(TM) High-Energy Polarizing Cube Beamsplitters handle laser-power densities up to 5 J/cm² and use multilayer dielectric film technology to minimize reflection and absorption losses. Units offer extinction ratio of > 500:1. Precision fused silica substrate and optical contact bonding prevents need for adhesive between prisms and improves parallelism of incoming and exiting beams. V-coat AR coating at design wavelength eliminates energy loss.

Jan 18, 2005 Designed for BeamStar FX Beam Profiler CCD cameras, variable attenuator option provides control over 4 orders of magnitude between 350–1100 nm wavelengths and suits pulsed lasers. BeamStar FX series beam splitters include UV grade fused silica wedge beam splitter that fits onto camera and another splitter that stands alone on its own adjustable stand. Each splitter reduces laser beam intensity by approximately 20 times.

Jun 05, 2003 Elliptical-shaped Plate Beamsplitters fit into circular apertures when oriented or mounted at 45°. They have 50% transmission/50% reflection ratio and are offered for visible spectrum and near-infrared in variety of sizes. Surface accuracy of ¼ wave reduces scatter and makes them suitable for imaging applications requiring diffuse axial or in-line illumination sources.
