Multiple λ/4 Order Waveplates

---

waveplate, also known as a retarder, is an optical device used to alter the polarization state of a light beam. It is typically made from transparent materials with specific birefringent properties, such as quartz, calcite, or mica. These materials have an optical axis parallel to the surface of the crystal, which can create an additional optical path difference or phase difference between two mutually perpendicular light vibrations.
