FOCtek offers high quality and high precision waveplate include Zero order Waveplate, Zero order Waveplate, Zero order Waveplate, Achromatic Waveplate, Fresnel Rhomb Prism.

Zero Order Waveplate

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