Non-Polarizing Beamsplitter Cube
Non-Polarizing Beamsplitter Cube is specially designed beamsplitter cube with less
polarization dependent. These Cube Beamsplitter
are cemented two right angle prisms, with beamsplitting coating on the internal
hypotenuse surface and all other 4 surfaces AR coated. By using a cube rather than
a coated plate, the displacement of the beam transmitted through the cube
is virtually eliminated.
