Polarizing Beamsplitter / PBS-12.7-7800
Polarizing beamsplitters consist of two right angle prisms. One of them is coated with dielectric multi-layer polarizing coating on the hypotenuse face. Polarizing beamsplitters split a monochromatic beam entering at zero degree into p-polarization as transmitted and s-polarization as reflected.

◦Four surfaces of the cube are coated with narrowband multi-layer anti-reflection coatings.
◦The losses of input beam of these products are minimized because of no absorption of the dielectric coatings.
◦For cube beamsplitters, unlike plate beamsplitters, beam deviations of transmitted beams and ghosts rarely occur.

| Attention | ▶Input beam from the prism on the side indicated by ○. When the light is incident from the side of the prism without mark, there is a possibility that the characteristics of the transmittance and extinction ratio will change. ▶The transmittance curves are based on actual measurements and might vary between manufacturing lots. ▶The surface flatness is the reflected wavefront distortion of the surface before coating. ▶Be sure to wear laser safety goggles when checking optical path and adjusting optical axis. |
