Abstract: A cold-test system for testing a camera at a cold temperature includes a test-chamber with a window, a nozzle, and a recirculator. The window is installed in the test-chamber so the camera is provided with a view of a test-target outside of the test-chamber. The nozzle is located proximate to a first edge of the window. The nozzle is configured to direct air from an air-source in a first direction and adjacent to an outside-surface of the window. The recirculator is located proximate to a second edge of the window opposite the first edge. The recirculator is configured to receive the air moving in the first direction and re-direct that air in a second direction opposite the first direction and adjacent to the air moving in the first direction opposite the window. The nozzle and the recirculator cooperate to form a bi-directional air-curtain proximate to the outside-surface.
