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 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 over a distance of λ/4 ...

PROBLEM TO BE SOLVED: To reduce the number of parts and to miniaturize an optical system such as an optical pickup used in a recording and reproducing equipment for a discoid recording medium by integrating a half mirror with a quarter-wave plate comprising a resin film. SOLUTION: At least,...
The mechanism behind half wave plate and quarter wave plate can be better understood by decomposing the incident and reflected electric fields into u- and v- axes respectively as sketched in Fig. 9(a). We consider Eui and Evi as incident electric field components in u- and v- directions ...
