Abstract:
1. A microscope, comprising: an illumination device, that generates a sheet of light extending along an illumination beam path for illuminating a sample region, the sheet of light having an illumination axis X in the direction of the illumination beam path and a transverse axis Y lying across the illumination axis X, the sheet of light having an approximately planar extension; and a detection device used to detect light that is radiated by the sample region along a detection beam path in a direction of a detection axis Z, wherein the angle between the illumination axis X and the detection axis Z are unequal to zero and the angle between the transverse axis Y and the detection axis Z are unequal to zero, wherein the detection device comprises a detection objective having a front lens, the detection objective positioned in the detection beam path, and the detection device further comprises an optical detection element located separately from the front lens of the detection objective, the optical detection element adjustable independently of said front lens of the detection objective, whereby adjustment of the optical detection element provides at least one of: a) continuously and variably changing the size of a detection image field, and b) continuously shifting a detection focal plane in the sample region wherein the illumination device comprises at least one illumination objective and an optical illumination element, the illumination objective comprising a front lens, the optical illumination element positioned separately from the front lens of the illumination objective, the optical illumination element being adjustable independently from the front lens, whereby the extension of the sheet of light in the direction of the detection axis Z is continuously variable by adjustment of the optical illumination element; wherein the optical illumination element is configured as a illumination zoom element: wherein the optical detection element is configured as a detection zoom element, and wherein the illumination zoom element and the detection zoom element are coupled via a control circuitry for setting the illumination zoom element as a function of the size of the detection image field provided by the detection zoom element.
