Ture order waveplate is a single plate which thickness is very thin, producing zero order retardation at specific wavelength. True order waveplate is mostly designed for wavelength range 1300– 1700nm for telecom application. These waveplates provide best possible angle, temperature and wavelength performance. The thickness of these waveplates are very thin (approx 100μm).
