Abstract
An interior rearview mirror system for a vehicle includes an interior rearview mirror assembly including an electrochromic reflective element. A transflective mirror reflector is established at a third surface of a rear substrate of the mirror assembly. The mirror reflector has at least three layers, including a metallic layer, a transparent conductive metal oxide layer and a transparent dielectric metal oxide layer. The metallic layer is closer to the electrochromic medium than the transparent conductive metal oxide layer and the transparent dielectric metal oxide layer, and the transparent conductive metal oxide layer and the transparent dielectric metal oxide layer are disposed between the metallic layer and the third surface of the rear substrate. The at least three layers of the mirror reflector are established at the third surface of the rear substrate by a vacuum deposition process that includes sputtering from multiple sputtering targets in a single vacuum deposition chamber.
