1. A method for optimizing the mirror uniformity and switching speed of a reversible electrochemical mirror of the type including a mirror electrode, a counter electrode, and an electrolyte disposed between and in electrical contact with the mirror and counter electrodes, wherein the electrolyte contains cations of an electrodepositable mirror metal, comprising the steps of:

  • applying a first negative voltage to the mirror electrode relative to the counter electrode so that mirror metal is deposited onto the mirror electrode at a first rate; and

    applying a second negative voltage more negative than the first negative voltage to the mirror electrode relative to the counter electrode so that additional mirror metal is deposited onto the mirror electrode at a second rate which is faster than the first rate, wherein the second negative voltage does not exceed a predetermined maximum drive voltage.
