Quarter/Half Wave Plate

Two common types of waveplates are available. One is Half-Wave Plate, which rotate the polarization direction of linearly polarized light, and the 2nd one is Quarter-Wave Plate, which converts linearly polarized light into circularly polarized light and vice versa. A quarterwave plate can be used to produce elliptical polarization as well.
