    摘要: The present invention relates to an optical imaging device, in particular for microscopy, with a first optical element group and a second optical element group, wherein the first optical element group and the second optical element group, on an image plane, form an image of an object point of an object plane. The first optical element group includes a first optical element with a reflective first optical surface and a second optical element with a reflective second optical surface. The second optical element group includes a third optical element with a reflective third optical surface. The first optical element and the second optical element are formed and arranged such that on formation of the image of the object point, in each case a multiple reflection of at least one imaging beam takes place on the first optical surface and the second optical surface.

    摘要: A catadioptric projection objective has a first objective part, defining a first part of the optical axis and imaging an object field to form a first real intermediate image. It also has a second, catadioptric objective part forming a second real intermediate image using the radiation from the first objective part. The second objective part has a concave mirror and defines a second part of the optical axis. A third objective part images the second real intermediate image into the image plane and defines a third part of the optical axis. Folding mirrors deflect the radiation from the object plane towards the concave mirror; and deflect the radiation from the concave mirror towards the image plane. The first part of the optical axis defined by the first objective part is laterally offset from and aligned parallel with the third part of the optical axis.
