Camera adapter for a medically optical observation device and the camera - adapter - combination

摘要

Camera adapter (19, 119, 219, 319) for the connection of a camera (21, 59, 159, 359) to an interface (13) comprising a parallel beam path of a medically optical observation device (1), wherein the interface (13) in the parallel beam path (9a, 9b) of the medically optical observation device (1) is located, and wherein– the camera adapter (19, 119, 219, 319) a devices connection part (41, 141) for connection to the interface of the medically optical observation device and a camera connection part (43, 143) for the connection of a camera (21, 59, 159) comprises,– the beam path (43, 143) by the camera adapter (19, 119, 219, 319, 419) along a linear optical axis runs,– the camera adapter (19, 119, 219, 319) an objective lenses combination (47, 147, 247, 347) with a minimum total focal distance in the range between 40 mm and 120 mm and– in the objective lenses combination (47, 147, 247, 347) is guided on the side of a lens combination (49, 149, 349) with a positive part focal length is present on the for camera page, a lens (57, 157, 357) with a negative part focal length follows,wherein– the camera adapter a total of four lenses (51, 53, 55, 57, 151, 153, 155, 157, 351, 353, 355, 357), and as leading on the side of the lens combination (49, 149, 349) a lens combination of three lenses, which together have a positive part focal length, and extends, final lens as a single lens having a negative part focal length, wherein the beam path after the extends, final lens runs convergently.
