A cabin monitoring system includes an interior rearview mirror assembly including a mirror head having a mirror reflective element that includes (i) a planar glass substrate, (ii) a transflective mirror reflector at the glass substrate and (iii) a light absorption film including a polarizer film. A camera accommodated by the mirror head views through the reflective element. A light emitter accommodated by the mirror head emits near infrared (NIR) light through the reflective element. The light absorption film attenuates greater than 60 percent of visible light and less than 30 percent of NIR light incident on the light absorption film and transmits less than 40 percent of visible light and greater than 70 percent of NIR light through the light absorption film. The camera captures image data representative of NIR light emitted through the reflective element and reflected from the interior cabin of the vehicle back through the reflective element.
