Document Type and Number:
Japanese Patent JPS5883818
Kind Code:
A
Abstract:
An electrochromic layer is applied to optical transmitting components, and electric-circuit connection to the layer enables temporary increase and decrease in the absorptance of the component. To increase the absorptance, a well-defined quantity of charge is supplied to the electrochromic layer; and to restore the initial condition, a well-defined quantity of charge is removed from the layer. Preferred fields of use are lenses, particularly eyeglass lenses, filters, and dimmable mirrors.
