1. A rearview assembly comprising:
an electrochromic element comprising:
a first substrate comprising a first surface and a second surface;
a second substrate comprising a third surface and a fourth surface, wherein the first substrate and the second substrate form a cavity; and
an electrochromic medium contained in the cavity;
an image sensor directed toward the fourth surface and configured to capture near-infrared light reflected off of an object and transmitted through the electrochromic element; and
a transflective film disposed adjacent to the fourth surface having a near-infrared light transmission level and a visible light reflectance level, the near-infrared transmission level being at least 50% independent of polarization of the near-infrared light.
