An optical system () for use in an underwater environment is proposed, wherein the optical system () comprises a housing which delimits an interior () of the optical system () with respect to the surroundings () in water-tight fashion, and a lens () with an outer surface (), wherein the housing comprises a mount (), wherein the lens () is received in the mount () in such a way that the outer surface () of the lens () is in fluid contact with water of the underwater environment when the optical system () is situated in the underwater environment, wherein the outer surface () of the lens () has an arched form, in particular a convex form, preferably a spherical convex form, wherein the lens () has a first arched contact face (), in particular a spherical contact face, and the mount () has a second contact face (), wherein the lens () is arranged in the mount () in such a way that the first contact face () presses against the second contact face () when the pressure of the surroundings () of the optical system () is greater than the pressure in the interior () of the optical system ().

Optical system for use in an underwater environment

The invention relates to a microscope () having an objective interchange apparatus () comprising a holder () for receiving a number of objectives () at respective holder positions () and an objective receptacle () which is configured for receiving an objective () and is arranged in an optical beam path () of the microscope (). The microscope () is characterized by an objective delivery device () which is configured for transporting in each case a selected objective () having an objective retainer () between its holder position (), which is delivered to a transfer position (&#xdc;P), and the objective receptacle (), wherein the objective receptacle () remains in the optical beam path () during the transport of the objective (). The objective retainer () has an outer centering diameter () as a reference surface, which diameter is guided against a lateral reference surface located in the objective receptacle () such that a reproducible positioning perpendicular to an optical axis () of the microscope () may be achieved.
