Abstract: Self-cleaning optic apparatuses and automobiles with self-cleaning optic apparatuses are provided. An exemplary self-cleaning optic apparatus includes an optic device for transmitting or receiving light. The optic device is located in a chamber. The self-cleaning optic apparatus further includes a window for transmitting the light. Also, the self-cleaning optic apparatus includes a photocatalytic coating on a surface of the window. Energy emitted from within the chamber activates a photocatalytic reaction in the photocatalytic coating.
