Low Order Waveplate
The low (multiple) order waveplate is designed to give a retardance of several full waves, plus the desired fraction. This result in a single, physically robust component with desired performance. However, even small changed in wavelength or temperature will result in significant changes in the desired fractional retardance. They are less expensive and find use in many applicatios where the increased sensitivities are not an important.

Dual Wavelength Waveplate
Dual wavelength waveplate is a multiple waveplate that provide a specitfic retardance at two different wavelengths, it's particularly useful when used in conjunction with other polarization sensitive components to separate coaxial laser beams of different wavelength.

Polarization Rotators
Polarization rotators offer 45deg or 90deg rotation at a number of common laser wavelength, the optical axis in a polarization rotator is perpendicular to the polished face of the optic. The result is that the orientation of in put linearly polarized light is rotated as it propagates through the device.
