Waveplates are used to change the polarization type of the incident radiation by
unequally phase-shifting its orthogonally polarized components.
Del Mar Photonics manufactures Multiple Order and Cemented Zero Order Quarter
and Half Waveplates from high quality artificial crystal quartz.
Multiple Order Waveplates are fabricated from a single 1 mm thick plate. The
retardence at the specified wavelength is equal to an integral namber of waves
plus 1/4 or 1/2 λ.
Zero Order Waveplates are made from two individual plates of crystalline quartz,
optically contacted with the direction of retardation opposed. The final
retardation is the net difference in retardation of the two plates, 1/4 or 1/2
λ.
