Abstract
A heated mirror is provided. The mirror includes a plastic or glass substrate. A contact surface is provided for receiving a resistive heating layer. A plurality of spaced electrodes are electrically coupled to the resistive heating layer for inducing a current in the resistive heating layer to heat the mirror assembly. The substrate is polished in the direction of current flow through the resistive layer. The assembly may also include a separate reflective layer.
