Non-Polarizing Cube Beamsplitters
High Power Polarizing Cube Beamsplitters were specifically developed
for use in high power pulsed and CW
laser applications. They are formed from two right angle, 45° prisms
optically contacted together. The hypotenuse
is coated with an all dielectric, polarization sensitive coating
designed to separate an incident, unpolarized, monochromatic beam into
its S and P polarization
components. The extinction ratio (TP/TS) exceeds
200:1 in the transmitted beam. The two orthogonally
polarized beams emerge from the cube at 90° with
respect to each other. All entrance and exit surfaces
are coated with a high efficiency, narrowband,
anti-reflection coating.
