  • Achromatic waveplate is similar to Zero-order waveplate except that the two plates are made from different materials, such as crystal quartz and magnesium fluoride. Since the dispersion of the birefringence can be different for the two materials, it is possible to specify the retardation values at a wavelength range. Hence, the retardation of the resulting waveplate can be made to low sensitivity to wavelength change.

  • The low (multiple) order waveplate is designed to give a retardance of several full waves, plus the desired fraction. This results in a single, physically robust component with desired performance. However, even small variation in wavelength or temperature will result in significant changes in the desired fractional retardance.
  • The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction. Zero order waveplate shows better performance than multiple order waveplates. It has broad bandwidth and a lower sensitivity to temperature and wavelength changes. It should be considered for more critical applications.
  • Polarization roators offer 45deg or 90deg rotation at a number of common laser wavelengths. The optical axis in a polarization rotator is perpendicular to the polished face of the optic. The result is that the orientation of in put linearly polarized light is rotated as it propagates through the device.

  • Itioptics provides true zero order waveplate-cemented and true zero order  single waveplate. True Zero Order Waveplate-Cemented is constructed of a true zero order waveplate and a BK7 substrate. As the waveplate is very thin and easy to be damaged, the Bk7 plate's function is to strengthen the waveplate. True Zero Order Single Waveplate is made of a very thin quartz waveplate which function as true zeor order.
