Low Order Waveplates
Feature and advantage:
- Single material, simple structure
- High angular sensitivity
- High damage threshold
- Low cost
PRODUCT
Detail
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. It is the most cost-efficient waveplate.
