ABSTRACT:
To provide an optical unit which can be driven with low electrical power, is controllable in its transmittance in visible light, has satisfactory spectroscopic properties in a light-screening state, and exhibits a life span extended by reducing the over-voltage upon the electrodes; and to provide an electrolytic solution to be used in the optical unit. An optical unit comprising a pair of opposing electrodes 2 and 3, and an electrolytic solution 1 comprising a solvent and a silver bromide dissolved therein, the electrolytic solution further containing a metal salt such as copper bromide to be co-deposited with silver, and the electrolytic solution being disposed between the opposing electrodes such that deposition/dissolution of silver is caused by drive-controlling these electrodes.
