An exterior rearview mirror element including a front element having a first front surface and a second rear surface. A cross-section of the second rear surface defines a first line. A rear element includes a third front surface and a fourth rear surface. Electrochromic material is located between the front element and the rear element. A spotter optic is located in the second rear surface of the front element. A cross-section of the spotter optic defines a second line. A transition region is disposed between the spotter optic and the second rear surface of the front element. A distance from a surface of the transition region to an intersection of the first line and the second line is between about 0.001 mm and 0.034 mm. At least a portion of the spotter optic includes a first radius of curvature and at least a portion of the first front surface includes a second radius of curvature, the first radius of curvature being smaller than the second radius of curvature.

Vehicle rearview mirror with spotter mirror

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.
