Abstract:
An optical device (100, 100A) and use thereof. The optical device (100, 100A) comprises: at least one lens (10, 10A), a lens barrel (20, 20A) and at least one heating element (30, 30A), the lens barrel (20, 20A) having a mounting chamber (201), the lens (10, 10A) being mounted in the mounting chamber (201) of the lens barrel (20, 20A), and the heating element (30, 30A), which generates heat upon being powered on, being arranged to contact the surface of the lens (10, 10A) on a side close to an object, so as to heat the lens (10, 10A); or, the heating element (30, 30A) having at least two wiring terminals (301, 301A), and at least two conductive elements (40, 40A) being respectively fixed at a position in contact with and electrically connected to the corresponding wiring terminals (301, 301A). According to the technical solution above, the heating elements (30, 30A) can generate heat to heat the lenses (10, 10A), so as to accelerate dispersing water adhered to the surface, have an active defogging and defrosting function, and can prevent against fogging or frosting.
