The most frequently used design is that of a quarter-wave mirror, where each optical layer thickness corresponding to one quarter of the wavelength for which the mirror is designed. Waveplate retardation can be measured by polarization analyser. Multiple layers are more effective over the entire visible spectrum.. Thanks. 0000010248 00000 n polarization analyser, which measures quartz waveplate thickness tolerance up to 0.05 micron. These layers are specified as quarter-wave optical thickness (QWOT), where TL =4NLtL cosθL.
