Waveplate

Detailed Product Description

WAVEPLATE

 

Waveplates are made from birefringent material. The velocities of the extraordinary and ordinary rays through the birefringent materials vary inversely with their refractive indices. The difference in velocities 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,

(δ-phase difference; d-thickness; ne, no-refraction index of extraordinary and ordinary rays; l-wavelength). At any   specific wavelength the phase difference is controlled by the thickness of the waveplate.

We provide many kinds of waveplates, such as Low- order waveplate, Cemented Zero-Order waveplate, Airspaced Zero-Order waveplate, True Zero-Order waveplate and Dual wavelength waveplate. Also we provide waveplates with different retardation as half-wave, quarter-wave, octadic-wave and foil-wave. If you want to order the specific retardation of waveplate for your system, We are able to design any type of Them for customers.

High precision and mass production are available upon requirement for waveplate in our company. Because we have high precision Waveplate-Master, which can test waveplate with retardation toleranceλ /600.
