タイトルまたは説明

Waveplates (retardation plates or phase shifters) are made from materials which exhibit birefringence. 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 a=2pi*d(ne-no)/l (a-phase difference; d-thickness of waveplate; ne, no-refractive indices of extraordinary and ordinary rays respectively; l-wavelength). At any specific wavelength the phase difference is governed by the thickness of the retarder. The thickness of a half waveplate is such that the phase difference is l/2-wavelength (true-zero order) or some multiple of l/2-wavelength (multiple order The thickness of the quarter waveplate is such that the phase difference is l/4 wavelength (true-zero order) or some multiple of l/4 wavelength (multiple order). Material: Optical grade Crystal Quartz Dimension Tolerance: +0.0, -0.2mm Wavefront Distortion: ****@***nm Retardation Tolerance: l/100 Surface Quality: 20/10 Scratch and Dig AR Coating: R<0.2% at center wavelength Standard wavelength: l
