Beamsplitter
Polarizing Beamsplitter Cube
A polarizing beamsplitter cube consists of two right angle prisms cemented together. The hypotenuse face of one prism is coated with a special multilayer dielectric coating.
Non-Polarizing Beamsplitter Cube
These cubes split the energy with minimal polarization sensitivity. The polarization states are about the same for the entrance and exit beams.those cubes are not intended for use with high powerlasers.
