[0025] Furthermore, a protective lens 3 is arranged inside the protective frame 2, and an electric heating coil 303 is arranged at the front end of the protective lens 3. The advantage of this arrangement is that the surface of the protective lens 3 can be heated by the electric heating coil 303 to reduce the temperature difference effect and avoid the generation of fog.

[0026] Furthermore, the front end surface of the protective lens 3 is coated with an anti-fog coating 301, and the anti-fog coating 301 is composed of a silicon dioxide coating and a titanium dioxide coating. The advantage of this setting is that through the setting of the anti-fog coating 301, the fog adhering to the surface of the protective lens 3 and affecting the normal operation of the camera body 1 can be reduced.

[0027] Furthermore, the front end surface of the anti-fog coating 301 is coated with a hydrophobic coating 302, and the hydrophobic coating 302 is made of a perfluorinated compound material.
