Polarizer Beamsplitters


PBS/PBF Series Introduction


The ProFlux™ polarizing beamsplitter’s wide angular aperture, excellent performance, and exceptional reliability offers engineers more design options. Recommended uses include polarization recovery and prepolarization in all 3 Panel HTPSliquid crystal projection displays, and as the imaging beamsplitter for certain single panel LCOS and near eye display architectures. In such applications, the PBS02 beamsplitter will provide exceptional image contrast and uniformity. ProFlux™ polarizers are a natural fit for any application that requires long service life, exceptional contrast, large angular apertures, and high light intensity or brightness. PBF02 optically flat beamsplitters are optimized for use at 45°, these beam splitters deliver good transmission and excellent contrast. Optically flat polarizing beamsplitters are a specific product engineered for imaging applications. The quality of both the transmitted and reflected wavefront meets the requirements of imaging applications in scientific instruments and displays.
