ABSTRACT:
A mirror reflective element suitable for use in an exterior rearview mirror assembly of a vehicle includes a glass substrate with a principal planar reflector portion having a principal mirror reflector disposed at a first or second surface of the glass substrate and with an auxiliary wide angle curved portion having an auxiliary mirror reflector coated at a curved recess established at a region of the second surface of the glass substrate by at least one of grinding and ablating. The curved recess has a cross-dimension size that is in the range from about 30 millimeters to about 80 millimeters, and has a radius of curvature that is in the range from about 200 millimeters to about 1,000 millimeters, and has a maximum recess depth that is in the range from about 0.11 millimeters to about 4.04 millimeters.
