Low Order Waveplate

Low Order Waveplate


The low order waveplate which can be replaced by multi-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 varitation in wavelength or temperature will result in significant changes in the desired fraction retardance.

● Thickness: 0.20-0.50mm
● High Damage Threshold
● Better Temperature Bandwidth
● Low Cost
