Abstract
The present invention provides an exhausting structure for lens. The exhausting structure is used for being disposed and fixed between a lens and an optical apparatus. The exhausting structure is formed with an air channel. The air channel has a first opening and a second opening. A projecting outline of the first opening in a projecting direction is separated from a projecting outline of the second opening in the projecting direction. Thereby, the air channel allows air to flow therethrough. Further, an air pressure caused by the change of the temperature in the exhausting structure can be released so as to prevent the air from pressing the lens or apparatus. The exhausting structure can also prevent a light from entering into the base through the air channel.
