Abstract (en)
[origin: WO2004006560A1] The invention relates to an illuminating device comprising a light source (1, 9), disposed along a line, for illuminating a line surface (3), and at least one linear optical element (2, 10). In order to compensate for the vignetting produced by the optical element (2, 10), a diaphragm (6) is provided that produces a numerical aperture that is variable in the direction of the line.
