Abstract
The utility model discloses a lens heating mechanism for preventing water and steam from forming fog and frost on a lens and a visibility tester for guaranteeing test precision. The heating mechanism comprises a heating element and a heat conducting element, wherein the heating element is contacted with a lens through the heat conducting element for transferring heat. The utility model further provides a visibility tester which comprises an optical antenna lens, wherein the lens heating mechanism is installed on the optical antenna lens. The lens is heated by the heating mechanism for promoting water and steam on the surface of the lens to fast evaporate, thereby preventing water and steam from forming fog and frost on the lens. As the heating mechanism is installed on the optical antenna lens of the visibility tester for preventing water and steam from forming fog and frost on the optical antenna lens, the system errors of the optical antenna lens caused by fog and frost can be eliminated, thereby guaranteeing the test precision of the visibility tester.
