The optical retardation can be given without the wavelength dependence for all visible ranges. It can be used in optical systems that change the polarization direction of the white-light source or spectroscopic measurement using polarization.
◦There are two types of Fresnel rhomb waveplate, a half waveplate can rotate the polarization orientation and a quarter waveplate can convert linear polarization into circular polarization.
◦As the entrance, exit and reflecting surfaces are processed to provide high parallelism and to minimize beam deflection.
◦When the linear polarization orientation of incident light is 45 degrees against the sides of square faces, the specified optical retardation will be obtained. The light will exit as linear polarization with –45 degrees orientation for the half waveplate, and as circular polarization for the quarter waveplate.
▶Fresnel rhomb waveplates made of synthetic fused silica are also available.
▶For Fresnel rhomb waveplates with different size, wavelength range, or retardation, please contact our Sales Division with your requests.
▶The quarter waveplate has optical axis shift (refer to the optical axis shift listed in the table below). Use the Fresnel rhomb waveplate by mounting it horizontally or vertically and rotating the polarization orientation of the incidence beam.
▶If finger prints or grease stain the polished surfaces of the Fresnel rhomb waveplate, the specified optical retardation will not be obtained. Use it carefully to prevent the side surfaces from contacting anything. (An FRH mounted in a holder is also available).
▶If the incidence angle varies, the specified optical retardation performance will not be obtained.
▶The Fresnel rhomb waveplate is less dependent to the wavelength, and it can be used in extended range outside the visible range. However the effectiveness of the anti-reflection coating drops outside the visible range and the transmittance decreases.
▶When the linear polarization orientation of incident light is aligned at 0 degrees or 90 degrees against the side of square face, the polarization orientation will not change output. (this is same for half waveplate and quarter waveplate)
