摘要：
The present invention relates to an afocal zoom system for a microscope with a shutter for controlling the depth of focus of the microscopic image produced by an object, wherein at least one shutter is disposed in front of the first lens group of the zoom system, viewed from the object, in the direction of the beam path passing through the zoom system, and/or at least one shutter is disposed on a lens group of the zoom system, the diameter of which can be varied in order to control the depth of focus, without causing vignetting of the edge beams.
