A method and a device for processing birefringent and/or optically active materials, wherein a light source ( 3 ) for polarized light and an analyzer assembly ( 8 ) and a light sensor ( 9 ) connected therewith are provided, so that between said components a processing of the birefringent and/or optically active material can be performed, so that the length of the pass-through path of the light through the material to be processed is changed, wherein the light is detected and processed simultaneously in a continuous or intermittent manner at the light sensor placed after the analyzer assembly, so that conclusions are derived from the changes of the light properties at the light sensor with respect to the processing state. Also provided is a combination phase plate manufactured accordingly.
