◦Polarizing beamsplitters split the light entering at zero degrees into p-polarization as transmitted and s-polarization as reflected.
◦Four surfaces of the cube are coated with multi-layer anti-reflection 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 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.
