Abstract

The invention relates to a telecentric modular zoom system for mapping an object plane on a sensor, in particular in a digital transmitted light microscope or incident light microscope having interchangeable lenses, comprising a fixed tube lens unit (LG) and multiple optical assemblies (LG, LG, LG, LG, LG), at least two of which are adjustably arranged relative to one another for the purpose of changing the magnification, characterized in that [sic]. According to the invention, a physical aperture (BL) conjugated relative to the rear focal points of the objectives used and having a variable diameter may be arranged in the beam path, wherein the rear focal points of the objective may be mapped in the space between a sensor image (BIE) and the intermediate image (ZB), the images of the rear focal points of the objectives (aperture BL) and the sensor image (BIE) do not lie within or migrate through the optical assemblies (LG, LG, LG, LG, LG, LG).
