Polarizing Beamsplitter Cube 20mm 632.8nm

PBS-20-6328

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.

Remark -
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.
