The beamsplitter cubes are constructed by cemented two matched right angle prisms. The hypotenuse is coated with partial dielectric coating.
¤ Easy to mount, is ideal for beam superposition.
¤ Less deformation.
¤ Polarization Sensitive
Cube Beamsplitters are recommended for use with collimated or nearly collimated beam. Convergent or divergent beam will contribute spherical aberration.
