Vehicle rearview mirror with spotter mirror
First Claim
1. An exterior rearview mirror element comprising:
- a from element defining a first surface and a second surface;
a rear element defining a third surface and a fourth surface;
electrochromic material located between the front element and the rear element;
a seal abutting the front element and the rear element, the seal defining a perimeter substantially surrounding the electrochromic material; and
a spotter optic disposed at the front element inside the perimeter defined by the seal, wherein at least a portion of the spotter optic has a first radius of curvature and at least a portion of the first surface has a second radius of curvature, the first radius of curvature being smaller than the second radius of curvature.

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.

30. An exterior rearview mirror element comprising:
-
a front element defining a first surface and a second surface, wherein a first electrode coating is disposed on the second surface; a rear element defining a third surface and a fourth surface, wherein the third surface faces the fourth surface and wherein a second electrode coating is disposed on the third surface; electrochromic material located between the front element and the rear element; and a spotter optic located at the second surface of the front element at a position wherein the second surface is substantially devoid of the first electrode coating, the spotter optic having a reflective coating; and at least a portion of the spotter optic having a first radius of curvature and at least a portion of the first surface having a second radius of curvature, the first radius of curvature being smaller than the second radius of curvature, wherein the reflective coating of the spotter optic is electrically coupled with the first electrode coating in contact with the electrochromic material. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
