Knight Optical supplies quality and cost effective low order wave plates made from optical grade AR-coated, crystallized quartz and mounted in durable blackened aluminium rings for ease of integration and handling. Quartz wave plates are suitable for both high and low power applications due to their negligible absorption and high transmission characteristics.

Key applications include:

  • Electro-optical modulation
  • Phase shift correction in medical microscopy
  • Optical isolators
  • Laser power attenuation

Wave plates can be used to rotate the direction of polarisation (λ/2 type) or convert linear to circular polarisation (λ/4 type). The effect of the wave plate is dependent on the retardation. Low order wave plates offer a cost effective compromise between angular and wavelength sensitivity and the higher price of zero order type plates.

Our quartz wave plates are available in all key laser wavelengths available to purchase directly from this page. Bespoke wavelengths, sizes and mounts are available through Knight Optical’s extensive custom optical service. Contact our technical sales team for more information.
