Abstract:
1. Method for producing a polarizing optical element by applying a multilayer structure onto a pseudospherical surface of a base optical element, the structure comprising an orienting first layer and a polarizing second layer itself comprising liquid crystal polymers and at least one dichroic dye, said dichroic dye having an angular orientation determined by the first layer, the method comprising the following steps: (a) producing the multilayer structure on a temporary support, said step (a) comprising the following substeps: (b) removing the multilayer structure from the temporary support, so as to obtain the structure in the form of a self-supported membrane; and (c) applying the multilayer structure onto the pseudospherical surface of the base optical element.
