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.
Zero Order Waveplate
We offer a wide choice of zero-order waveplate, low order Waveplate and multiple-order waveplates made from crystalline quartz.
These zero order waveplates are made from two pieces of quartz, either cemented or optically contacted, with their optic axes perpendicular to each other.
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 wavelength changes. It should be considered for more critical online orderings.
