CVI Laser's TFPN thin-film plate polarizer works at 45° so the reflected and transmitted beams are separated by 90° and are orthogonally polarized, just like a cube polarizer. It can be used as either a beamsplitter or beam combiner without angle tuning or complicated alignments. The dielectric coating is durable and dense, so there is no wavelength shifting, and it can be done at any visible near-infrared (VIS-NIR) wavelength.
