High Power PBS
The beamsplitter interface of these cubes uses an epoxy-free, optical contact bond, which minimizes absorption and scattering loss. Each surface is polished to a high flatness, and this precision polishing of the internal surfaces is what enables them to achieve optical contact. As such, Crystock is able to manufacture compact, thermally stable beamsplitter cubes with high transmission and minimal beam displacement.
The cubes separate the s and p polarization components by reflecting the s component at the dielectric beamsplitter coating while allowing the p component to pass. For the highest polarization extinction ratio, use the transmitted beam, which offers an extinction ratio of Tp:Ts > 1000:1.
