Low reflectance glare optic

摘要

A rearview assembly is disclosed for use in a vehicle for providing a rearward view from the vehicle. In one example, the rearview assembly includes at least one substrate having a partially transmissive coating and a light sensor proximate the at least one substrate. The rearview assembly further includes a secondary optic. The secondary optic has a first surface facing outward toward the at least one substrate and a second surface facing inward toward the light sensor. Vertical flutes extend uniformly along the first surface and horizontal flutes extend uniformly along the second surface. The secondary optic is configured to control a field of view of the light sensor.

1. A rearview assembly for use in a vehicle for providing a rearward view from the vehicle, the rearview assembly comprising:
at least one substrate comprising a partially transmissive coating; a light sensor proximate the at least one substrate; and a secondary optic comprising: a first surface facing outward toward the at least one substrate; a plurality of vertical flutes proximate the first surface; a second surface facing inward toward the light sensor; and a plurality of horizontal flutes proximate the second surface, wherein the secondary optic is configured to control a field of view of the light sensor and the secondary optic is configured to have a reduced reflectance, and wherein an orientation of the plurality of vertical flutes and the plurality of horizontal flutes provide for the field of view with the reduced reflectance.
