Abstract

An optical imaging device, in particular a lens system, has a system diaphragm (1). An aperture of the system diaphragm (1) is adjustable in its opening diameter (D). The axial position of the aperture of the system diaphragm (1) with respect to the optical axis (4) of the system diaphragm (1) is fixed in dependence on the opening diameter (D) of the system diaphragm (1).
