Beamsplitter Cubes

Beamsplitter Cubes

The beamsplitters are made of two cemented right angle prisms. One of the prisms bear a partially reflective silver coating in the inner surface.

This grants a splitting ratio which is constant over a broad spectral range and shows little dependence on the polarization of the light. Metallic coatings are slightly absorbing.

The outer surfaces are coated with broadband antireflection layers. By default the prisms are delivered without mount.

The cubes are available for the wavelength ranges 400-700 nm and 600-900 nm.

On one of the ground side surfaces the prism bearing the beamsplitter coating is marked by a line parallel to the inner surface. On the opposite side the direction with the specified prismatic beam deviation (<2') is indicated. The inner structure of the cubes and the coating is highly symmetrical. Therefore, the direction of use has only a minor influence on the properties.

For these beamsplitters we also offer mounts (Article-No.: MTW) .
