Abstract
A lens assembly includes a lens, a lens barrel, and a heater element. The lens has an inner surface and an outer surface. The lens barrel supports the lens and defines an optical axis, the lens arranged along the optical axis such that the inner surface of the lens is within the lens barrel and the outer surface of the lens is outside the lens barrel. The heater element is in intimate mechanical communication with the inner surface of the lens and has a heater element electrical lead extending radially therefrom to provide power to the heater element. Lens heating methods are also described.
