Quartz Retardation Plates, or Waveplates, in general, induce a phase retardation between orthogonal polarization directions. Beam propagation is perpendicular to the direction of the crystalline optic axis. Retardation is dependent on the rotation of the plate about the beam direction. The maximum amount of phase retardation, G, for a waveplate of thickness t is given by G = 2p Dn t / l where Dn is the birefringence of quartz at the wavelength of use and l is the wavelength.
Standard retardance tolerances for a quartz waveplate correlate to a thickness tolerance of +/- 0.4 µm.
All retardation plates are manufactured on a Custom Basis; please submit a Request for Quotation. Print, specifications and quantity required.
