The low order waveplate is the most inexpensive design but is very sensitive to variations in wavelength and temperature.
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 the desired performance.
However, even small variation in wavelength or temperature will result in significant changes in the desired fractional retardance.
Choosing the right waveplate for your application can be a bewildering task, as we offer a wide range for many different uses.
Feel free to call us for assistance. Our experienced staff is only too pleased to help you with the decision process.
As with all of our optics, we will gladly provide these items custom designed to your particular requirements. As an alternative, we offer a selection of standard items as specified below.
