Coating R 0 2 Optical Waveplate - China

Waveplates ( retardation plates or phase shifters) are made from

materials which exhibit birefringence.

The velocites of the

extraordinary and ordinary rays through the birefringent material

varies inversely with their refractive indices.

This 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 , where α is phase difference; d is

thinkness of waveplate; ne, no are refrective indices of extraordinary

and ordinary rays respectively; λ is wavelength.

At any specific

wavelength the phase difference is governed by the thinkness of the

retarder.

Standard Waveplates

Including full- wave ( λ ) , half- wave ( λ / 2) , quarter- wave ( λ / 4) and octadic- wave ( λ / 8) plates are widely used in synthesis and analysis of light in various states of polarization.

Waveplates ( retardation plates or phase shifters) are made from materials which exhibit birefringence.

The velocites of the extraordinary and ordinary rays through the birefringent material varies inversely with their refractive indices.
