Abstract:
A pop-up external lens washing system has an extendable aiming fixture configured to aim a lens cleaning spray at an external lens which is exposed to the elements and apt to become soiled with debris. The extendable nozzle assembly is configured to be aimed toward the external lens by the extended aiming fixture during the washing operation only and has at least one laterally offset washing nozzle projecting from the aiming fixture to a spray washing fluid toward the external lens surface, spraying at a shallow, glancing spray aiming angle to impinge upon and wash the lens external surface.
