Description

Polarising beamsplitter cubes conveniently divide any beam into two polarised components. They also make excellent variable beamsplitters, particularly for sources such as lasers with polarised output, used with a half-wave plate to vary the incident polarisation state. This arrangement allows continuous variation of the split ratio over a wide range with negligible losses.
We offer cubes for both the visible and near IR ranges, both with multilayer AR coatings for maximum efficiency. Note that the polarisation purity of the transmitted beam is considerably better
than the reflected beam. For even better performance see the crystal polarisers below.
