A wave plate or retarder is an optical device that alters the polarization state of a light beam travelling through it.
A typical wave plate is simply a birefringent crystal like quartz ,calcite etc. with a particular thickness.
If a beam of parallel light passes perpendicularly through a wave plate, the light beam is split into two components due to its double refracting properties.
The two components have planes of oscillation perpendicular to each other and slightly different phase velocities.
For a quarter-wave plate, the thickness of the quartz plate is chosen in such a manner that the light component whose electric field vector oscillates parallel to the rotation lever lags by a I /4 behind other perpendicular oscillating light component. For a half-wave plate the thickness is chosen so that the created phase difference is I /2.
