MSE PRO™ BK7 Laser Line Polarizing Beamsplitter Cubes
MSE supplies offers BK7 Laser Line Polarizing Beamsplitter Cubes. It consists of a pair of right angle prisms cemented together. The hypotenuse face of one prism is coated with a special multilayer dielectric coating. When non-polarized light is normally emerging through two adjacent faces in perpendicular directions and polarized orthogonally to each other. The transmitted beam is p-polarized while the reflected beam is s-polarized. When a linearly polarized light is incident, it is similarly divided into two beams in a ratio depending upon the orientation of the electric field vector of the incident light beam. These polarizing beamsplitters are available for many common laser wavelengths and broadband ranges.
MSE Supplies can offer a variety of optical components. Please contact us for customization or bulk orders.
