Low-order Waveplate

The low (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 desired performance. However, even small variation in  wavelength or temperature will result in significant changes in the  desired fractional retardance.
Thickness: 0.2-0.4 mm
High Damage Threshold
Better Temperature Bandwidth
Low Cost
