This invention relates to a camera for imaging inside a vacuum environment and outputting video, and the purpose of this invention is to provide a camera for vacuum environments which is capable of checking for leaks (air leaks) from said camera in a state in which the camera is installed in a vacuum environment. This camera (4a) for vacuum environments is provided with an airtight structure frame (7a, 7b, 7c, 7d) which is strongly resistant to vacuum environments. To the frame, a leak check port (19a) can be attached for introducing a leak checking gas inside the frame (inside the camera (17)) from outside of the vacuum environment. |
