Allgemeine Optik

Prismen & Rauten

Erzeugen Sie Viertelwellen-, Halbwellen- oder andere Phasenverschiebungen mit breitbandigen Quellen oder mehreren Wellenlängen im Bereich von 8 bis 12 µm.

These Fresnel prisms and rhombs use total internal reflection to produce a phase change between s- and p-polarizations that is nearly wavelength independent. This enables straight-through and angled components with virtually any desired retardation.

Prisms & Rhombs Design Guide

Select various geometries to produce different polarization effects and also angles or offsets in the transmitted beam path.

Notes

Quarter-Wave Prism

Turns the beam path.

Quarter-Wave Rhomb

The output beam is parallel but displaced from the input.

Half-Wave Rhomb

Output polarization can be rotated. The output beam is parallel but linearly displaced from the input beam.
