Abstract
A fluid cooled lens assembly is provided which comprises a housing mounting a lens or window where a window is a lens with infinite radius of curvature therein and a cooling passage included in said housing for directing coolant fluid around the lens periphery from an inlet through an outlet in the housing. Turbulators in the form of protuberances spaced throughout the cooling passage restrict the flow of fluid and thereby cause turbulence to assist and enhance the heat transfer effect of the fluid. The cooling passage turbulators are formed within one of a pair of mounting rings comprising the housing.
