From prototype to production, Focus Technology manufactures and delivers precision quality waveplates for ultraviolet (UV), visible (VIS), and infrared (IR) wavelength ranges.

Zero Order Quartz Waveplates are constructed of two multiple order waveplates which is designed to give a retardance of zero full waves, plus the desired fraction.
