Beamsplitter

Common beamsplitters are used to split or combine laser beam.

However polarization beamsplitters are used to split or combine

two perpendicular polarization laser beam. The performance of

beamspitters is mainly dependent on the coating specifications.

Beamsplitter Cube

Cube beamsplitters are constructed by cementing two precision right angle prisms

together with appropriate interference coating on the hypotenuse surface. The

absorption loss to the coating is minimal transmission and reflection approach 50%

(average) though output is partially polarized.

Coating:

Hypotenuse face:---------------------------Partial reflectance

All input and output faces:---------------------AR Coating
