VARIABLE MICROSCOPE SYSTEM
A variable microscope system, which, beginning at the object plane, includes a main lens system, a zoom lens system consisting of several lens groups, and a relay system connected in series to the zoom lens system. In the microscope system, according to the invention, at least one main lens system for infinite mapping of an object is provided and the zoom lens system is designed in such a way that the infinite beam path from the lens system is mapped in an intermediate image, wherein an aperture collimation is provided in a subsequently positioned relay system. An advantage of the microscope system, according to the invention, versus prior art lies in an improved eye pupil adjustment to the illumination as well as to the observation of samples with the contrast method.
1 . A variable microscope system, which, beginning at an object plane, comprises:
at least one main lens system; and
a zoom lens system consisting of one or several lens groups;
wherein
the main lens system for mapping of an object has an infinite beam path, and
the zoom lens system is structured such that the infinite beam path from the main lens system is mapped in a fixed intermediate image plane, wherein
aperture collimation is provided in a in series connected relay system.
2 . The variable microscope system, according to claim 1 , wherein the relay system is structured to map a first intermediate image in an eyepiece image plane or onto a camera.
3 . The variable microscope system, according to claim 1 , wherein the relay system comprises an imaging system with a binocular tube.
4 . The variable microscope system, according to claim 1 , further comprising an illumination beam path reflector and a field stop, positioned in the intermediate image plane.
5 . The variable microscope system, according to claim 1 , comprising the following design data:
