<p>The system has an electron receiving surface (29) arranged proximate to an object plane (27) as a main plane (67) of an objective lens (39). A light exit surface (55) is arranged far distant from the object plane than the main plane. A maximum cross sectional area of a light guide body (23) of a scintillator arrangement (21) in a vertically oriented plane is two times larger than a surface area of the surface. A maximum expansion of the area in the oriented plane is smaller than distance between the object plane at a nearest arranged location of the surface and the oriented plane.</p> |
