  • Waveplate (Phase Retarder)

Waveplates

Waveplates (retardation plates or phase shifters) are made from materials which exhibit birefringence. The velocities of the extraordinary and ordinary rays through the birefringent material vary inversely with their refractive indices. This velocity difference gives rise to a phase difference when the two beams recombine.

In the case of an incident linearly polarized beam, this is given by δ=2πd(ne-no)/λ, where α is phase difference; d is the thickness of waveplate; ne, no are refractive indices of extraordinary and ordinary rays respectively; λ is the wavelength. At any specific wavelength, the retarder's thickness governs the phase difference.

Standard Waveplates

China Star Optics' waveplates, including full-wave (λ), half-wave (λ/2), quarter-wave (λ/4), and octadic-wave (λ/8) plates are widely used in the synthesis and analysis of light in various states of polarization. The standard wavelengths of TrueOptics' waveplates are listed below for your reference.

Other wavelengths within the range of 200-2300nm are also available upon request.

  • Polarization Rotator

Low-order waveplates are much better than multi-order wave-plates because of their thinner thickness (less than 0.5 mm). Better temperature (38), Wavelength (1.5nm) incident angle (4.5°) bandwidth and high damage threshold make it widely used in common applications. Also, it is economical.

Other wavelengths, sizes and coatings are available upon request.

  • Zero-Order Waveplates

A quarter- or half-wave retarder made from two plates of quartz with their fast axes crossed, the difference in thickness between the two plates determines the retardance. Zero-order retarders provide accurate retardance over a broad range of wavelengths and are more durable than single-element retarders.
