Multiple Order Waveplates

With an appropriate choice of thickness, any degree of retardance may be 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 waveplates are 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. A multiple order waveplate provides an economical choice for retardance control in a stable wavelength and temperature environment.

Quarter Waveplate Design

Quarter waveplates transform polarized light between linear and circular polarization. The orientation of the input linearly polarized light must be incident at 45° to the crystalline axis.

Half Waveplate Design

Half waveplates rotate the orientation of linear polarized light. The rotation angle is twice the angle between the incident polarized light orientation and the crystalline axis. Thus, a half waveplate rotates vertical polarization 90° to horizontal polarization, when the linear polarization is oriented at 45° to the crystal axis.

Note:  Mounted waveplates will have approximately an 85% Clear Aperature
