This cemented beam splitter provides the greatest angular deviation between the two output beams, and is most commonly used as a polarization analyser. In the first prism both ordinary and extraordinary beams travel collinearly with different refractive indices. At the interface the beams are interchanged, so that the ordinary beam enters a medium of lower refractive index and is refracted away from the normal. The extraordinary beam experiences a higher refractive index and is refracted towards the normal. The divergence angle between them is then further increased at the calcite/air exit surface.
