Abstract

An anodic film on a nickel mirror makes the mirror either re-flective or opaque depending upon the field across the anodic film. It has been found that an anodic film exists on the surface of a nickel mirror which is anodically prepolarized in a di-lute aqueous alkali solution. Optical modulation of the film is brought about by reversible electro-chemical redox reac-tions.
