Diode Laser Non-Polarizing Cube Beamsplitters

The Diode Laser Non-Polarizing Cube Beamsplitter are used for those applications where polarization effects must be kept to an absolute minimum. Unlike the hybrid coatings used in the conventional cube beamsplitters, these all-dielectric coatings are designed for high performance at specific wavelengths, where they easily exceed the performance of any other available beamsplitters. Being totally dielectric, they have negligible absorption. The current range includes a coating designed specifically for diode lasers at 670, 780 and 830 nm. At these wavelengths, this cube beamsplitter coating reflects 50 +/-5% of incident light. The S ad P components of the reflected (and therefore transmitted) beam differ by less than 5%. Both components are within +/-2.5% of the average polarization performance.
