Half (λ/2) waveplate. A linearly polarized beam incident on a half-wave crystal quartz waveplate emerges as a linearly polarized beam, but is rotated such that its angle to the optical axis is twice that of the incident beam. Half-waveplates can therefore be used as continuously adjustable polarization rotators. Such waveplates are used to rotate the plane of polarization, as well as for electro-optic modulation and as a variable ratio beamsplitter when used in conjunction with a polarization cube.
Zero-order waveplates are generally preferred because they are least sensitive to variations in wavelength, angle of incidence and temperature.
