Fresnel Rhombs Retarder

Fresnel Rhombs Retarder 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.   Retardation we offer can be with L/2 or L/4 retardation with application wavelength 400-2000nm and also can be 200-2000nm, The design can be design with single and double design, The application like achromatic wavepalte, But with much broadband wavelength application, If have similar requiments, Pls contact me freely, thanks, best wishes, Shelly United photonics Technology
