ABSTRACT:
A mirror element comprising a front element, a rear element, electrochromic material therebetween, and a spotter optic located at the rear surface of the front element. At least a portion of the spotter optic has a first radius of curvature and at least a portion of the front surface of the front element has a greater second radius of curvature. A line perpendicular to the front surface extends through both the electrochromic material and the spotter optic. A first electrode coating and a second electrode coating are activated to activate the electrochromic material in order to dim a reflection off of the mirror element. A reflective coating of the spotter optic can form a portion of the first electrode coating. The first electrode coating and the reflective coating can overlap.
