Abstract
An optical device for use under significantly varying ambient pressure is provided comprising a housing, a transparent element, a first sealing device and a protection apparatus. The housing has an interior part, an environment outside the housing and a recess in a first region. The transparent element is arranged in the first region in a region of the recess. The first sealing device is sealing a first sealing gap between the transparent element and the housing. Furthermore, the first sealing device is sealing the interior part of the housing relative to the environment of the housing up to a first pressure level. The protection apparatus is arranged outside the housing and is displaceable from a first functional position into a second functional position. Furthermore, the protection apparatus, in the first functional position, covers the transparent element and seals the first region relative to the environment of the housing in such a way that a pressure in an intermediate space between the protection apparatus and the first region is not higher than the first pressure level if an ambient pressure in the environment of the housing exceeds the first pressure level. Finally, the protection apparatus, in the second functional position, leaves the transparent element uncovered.
