Abstract
The invention relates to a pinhole disk, which can be used in a transmitted light mode as a filter disk, in particular in confocal microscopes, and consists of an optically transparent material with an inner hole having a fixed outer radius rmax and inner radius rmin. The optically transparent material is covered with a non-transparent layer, at least over a large area, the area being provided with a pattern of transparent pinholes. The pinholes are arranged according to a rule, in such a way that a quasi-uniform point density is obtained on the disk.
