Soleil - Babinet Compensators are zero order wave plates with variable retardation over a wide range of wavelengths. These are used to measure state of polarization or to produce certain retardation for different wavelengths. It consists of a birefringent wedge which is movable and another birefringent wedge which is fixed to a compensator plate. The retardance is adjusted by moving the position of the movable wedge relative to the fixed wedge. Holmarc’s Soleil - Babinet compensators are equipped with precision digital micrometer and are made by laser grade quartz crystals. The wedges are AR coated to reduce reflection losses.
