Optical imaging device and imaging method for microscopy
An optical zoom device for setting an imaging scale of an imaging device, which is configured for imaging an object on an image plane of an image recording device using a microscope objective, comprising an optical element arrangement is disclosed. The optical element arrangement includes an object-side zoom entrance for optical connection to an objective exit, in particular a collimated objective exit, of the microscope objective and includes an image-side zoom exit for optical connection to an image recording entrance of the image recording device. The optical element arrangement includes a tele arrangement designed according to the teleobjective principle, which includes a first optical element group with negative refractive power and a second optical element group with positive refractive power, assigned to the first optical element group for setting the imaging scale, wherein the first optical element group is arranged at the zoom exit and the second optical element group is arranged on the objective side of the first optical element group.
