High Power Polarizing Beamsplitter / PBSHP-20-2570

Polarization beam splitter specially designed for pulsed lasers such as Nd-YAG lasers and Yb lasers.
High Power Polarizing Beamsplitters have more laser durability compared to our standard Polarizing Beamsplitters (PBS).

◦Polarizing beamsplitters split a monochromatic beam entering at zero degrees into p-polarization as transmitted and s-polarization as reflected.
◦Four surfaces of the cube are coated with narrowband multi-layer anti-reflection coating.
◦The losses of input beam of these products are minimized because of no absorption resulting from the dielectric coating.
◦For cube beamsplitters, unlike plate beamsplitters, beam deviations of transmitted beams and ghosts rarely occur.

Guide ▶Please contact our Sales Division for customized products. (Customized on size
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 surface flatness is the reflected wave front distortion of the surface before coating.
▶Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
