A vehicle mirror assembly 10 is provided. The vehicle mirror assembly
10
comprises a base 12 comprising a first base ellipsoidal portion 32
having a constant first minor axis 27 and a major longitudinal axis
38. The base 12 further comprises a second base ellipsoidal portion
34 having a second base minor axis 27" and sharing the major longitudinal
axis 38. The first minor axis 27 and said second minor axis
27" are merged to form a common minor axis 27. The major longitudinal
axis 38 intersects the common minor axis 27 in a position non-coincidental
with a center of said common minor axis 27. The mirror assembly 10
further includes a dome lens 14 conforming to the base 12. The dome
lens 14 comprises a first surface elliptical portion 48 having a
longitudinal axis radius of curvature R1 taken along the major longitudinal
axis 38 and a first minor radius of curvature R3 taken along the
first minor axis 27. The first surface elliptical portion 48
conforms to the first base ellipsoidal portion 32. The dome lens 14
further includes a second surface elliptical portion 50 having the longitudinal
axis radius of curvature R1 taken along the major longitudinal axis 38
and a second minor radius of curvature R4 taken along the second minor axis
27". The second surface elliptical portion 50 conforms to the second
base ellipsoidal portion 34.
