Zero-order Waveplate, Air-spaced, FOCtek

Zero Order Waveplates, FOCtek

The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction. Zero order waveplate shows better performances than multiple order waveplates, it has broad bandwidth and a lower sensitivity to temperature and wavlenght changes. It should be considered for more critical online_orderings.
