LOW ORDER WAVEPLATE
The low 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.
Low Order Waveplates are much better than the multi-order waveplates because of its thinner thickness(less than 0.5mm), better temperature(38degC), wave length(1.5nm) and incidence angle(4.5deg) bandwidth and high damage threshold. These properties make it widely used in common applications.
