Claim 17:
18. A method for subjecting a work region containing point emitters to a light field, comprising:
at least approximately obtaining at least two positions at which point emitters are located in the work region; and
subjecting the work region to the light field having zeros at the at least two obtained positions by:
providing light from a light source to at least one modulator which impresses different changes in at least one property of the light on different components of the light;
controlling the at least one modulator by a zero control pattern such that the summation of the amplitude distributions of the light components, which were guided via the modulator, have zeros at the at least two obtained positions that are specifiable independently of one another within the work region, wherein the zeros each adjoins regions in which this summation of the amplitude distributions differs from zero; and
guiding the light from the at least one modulator into the work region.
