Aperture stop device
First Claim
1. An aperture stop device in an observation beam path of a microscope, the microscope having at least one adjustable observation parameter, comprisingat least one aperture stop with an adjustable aperture in an observation beam path of the microscope, which receives an aperture signal representative of an aperture to be adjusted,a control unit for outputting the aperture signal to the aperture stop in dependence at least on a respectively adjusted value of the at least one adjustable observation parameter, wherein the at least one adjustable observation parameter is at least one magnification factor,a memory storing different relationships between at least two different values of the aperture and the adjusted value of the available magnification factors, wherein each different relationship describes the aperture to be adjusted as a function of the adjusted value of the available magnification factors to implement different transmission characteristics in the observation beam path, anda selector device for selecting one of the stored different relationships based on a desired transmission characteristic in the observation beam path for application of the selected relationship to the aperture of the aperture stops.

Abstract
An aperture stop device is provided for use in a microscope with at least one adjustable observation parameter. The aperture stop device includes at least one aperture stop (50a, 50b) with an adjustable aperture, that is to say with an adjustable stop opening. The aperture stop (50a, 50b) is adapted to receive an aperture signal representative of an aperture to be adjusted. In addition the aperture stop device includes a control unit (52) for output of the aperture signal to the aperture stop (50a, 50b) in dependence at least on the respectively set value of the observation parameter of the microscope.
