BEAMSPLITTER CUBE
BEAMSPLITTER CUBE
POLARIZING BEAMSPLITTER CUBE prisms split unpolarized light into transmitted p-polarized and reflected s-polarized beams via dielectric coatings at Brewster angles. They achieve >1000:1 extinction ratios and >90% transmission for p-light, ideal for polarization-sensitive systems like interferometers and projectors (420–1600 nm)
MT-optics's polarizing beamsplitter (PBS) cube is composed of a pair of precision high-tolerance right-angle prisms cemented together. One of the prisms has a partially reflective metallic-dielectric coating applied to its hypotenuse. The incident lightshould enter the prism with the coated hypotenuse in order to minimize power passing through the optical cement. The PBScan split the unpolarized beam into two orthogonal, linearly polarized components. P-polarized light is transmitted, whiles-polarized light is reflected, both with negligible absorption. The extinction ratio is better than 1000:1 for beamsplitters madewith N-BK7 glass, and better than 100.1 for beamsplitters made with UV fused sllica. These cubes are recommended for usein pulsed laser systems and for purifying polarization in multimode high-power lasers.
NON-POLARIZING BEAMSPLITTER CUBE prisms maintain near-identical splitting ratios (50:50) for all polarization states, with |Tp-Ts| <8% and minimal polarization-dependent loss. Designed for polarization-insensitive applications in imaging/LIDAR (400–1600 nm)
MT-optics's non-polarizing beamsplitter (NPBS) cube is composed of a pair of precision high-tolerance right-angle prismscemented together with a metallic-dielectric coating on the hypotenuse of one of the prisms. The low polarizationdependence of the metallic-dielectric coating allows the transmission and reflection of s and p-polarization states to bewithin 5% of each other. This means that the NPBS will not need to change the polarization of the incident beam. We can supply both broadband and single wavelength for the NPBS. In order to produce maximum transmission efficiency for the appropriate wavelength range, an antireflective coating can be applied to each face of the beamsplitter.
