Non-Polarization Beamsplitter Cube(NPBS)

Non-polarizing beamsplitter cubes consist of a pair of precision right-angle prisms that have been carefully cemented or mounted together to minimize wavefront distortion. It provides a true 50/50 split at a specific laser wavelength (e.g., 632.8), regardless of the incoming polarization. These beamsplitters are particularly useful with randomly polarized lasers and are specifically designed for applications in which polarization effects must be at a minimum. 
Non-polarizing beamsplitter cubes are specifically designed to maintain the reflected and transmitted beam where the incident laser radiation polarization characteristics are applied. This occurs because these devices are less sensitive to polarization and because they are designed from (or are at least coated with) dielectric materials, which provide negligible absorption.  The end result is stable performance regardless of the energy sources involved.
CRYLIGHT Optoelectronics provides different sizes of Non-polarizing beamsplitter cubes. In addition to the standard coating index described on this page, different beam splitting ratios and customized coatings can be provided according to customer requirements.
