Some external factors, such as the variation of wavelength, ambient temperature, and the angle of the incident might all have impacts on the retardation of waveplates and retarders. The most common waveplates are half waveplates and quarter waveplates. A half waveplate, sometimes equivalently ...

The meaning of HALF-WAVE PLATE is a crystal plate that reduces by 1/2 cycle the phase difference between the two components of polarized light traversing it.
Common Types and Applications The most common types of waveplates are quarter-wave plates (λ/4 plates) and half-wave plates (λ/2 plates), where the difference of phase delays between the two linear polarization directions is π/2 or π, respectively, corresponding to propagation phase shifts...
