Polarizing Optic—WaveplateOverview Waveplate Overview Waveplates (retarders) are made from birefringent materials which introduce a phase difference between the fast and slow principal axis of the waveplate. The optical axis of waveplate is parallel to the face. Light incident normal to the surface will be split to components polarized parallel and perpendicular to the optical axis with different refractive index and velocity in this device. The difference in velocities gives rise to a phase shift which is called retardance. At any specific wavelength the phase retardance is governed by the thickness...

Polarizing Optic—AchromaticWaveplate Achromatic Waveplate Achromatic waveplate is similar to zero order waveplate except that the two plates are made from different birefringent crystals. Since the dispersion of the birefringence of two materials is different, it is possible to specify the retardation values at a broad wavelength range. So, the retardation will be less sensitive to wavelength change. In other words, it can be used at a broadband wavelength range.
