Multiple Order Waveplates

Multiple order waveplates with an appropriate choice of thickness, any degree of retardance may e achieved at any wavelength for which quartz is transparent. However, the minimum thickness necessary to achieve a mechanically strong part corresponds to several full waves of retardance. The multiple order waveplate is designed to give a retardance of several full waves, plus the desired fraction. This results in a single, physically robust component with the desired performance.

Quarter Waveplate

A quarter-wave plate can transform light from linearly-to circularly-polarized, if oriented at 45º to the indicated crystal axis.

Half Waveplate

A half-wave plate can transform light from vertically- to horizontally-polarized, in effect rotating the polarization 90º, if oriented at 45º to the indicated crystal axis.
