An imaging system includes a mirror assembly. An imager is centrally disposed on the mirror assembly and configured to acquire an image of a biometric feature of a vehicle occupant within a field of view of the imager. A first light source is disposed within the mirror assembly and configured to project a ray of light onto a target surface corresponding to an eye of the vehicle occupant. The first light source is spaced from the target surface by a first distance. The first light source is spaced from the imager by a second distance. The ray of light forms an angle of incidence having legs extending from the target surface to the first light source and to the imager, and wherein the first distance and the second distance are operable to define the angle of incidence in the range of 5° to 15°.
