The invention relates to an illumination device, in particular for a confocal microscope. The object of the invention is to provide an illumination device which operates with a plurality of current-modulated semiconductor-based light sources, in which the light emission is as free as possible from distortions due to dynamic delays of the light emission in the output beam. To this end, the proposed illumination device comprises:

Illumination device for a confocal microscope

The invention relates to a method for modulating the resonant frequency of an optical resonator () in accordance with a periodic, not necessarily harmonic, modulation signal (U(t)). Fast modulation of an optical resonator is intended to be made possible in which the current resonant frequency follows the modulation signal (U(t)) as precisely as possible, and specifically at a fundamental frequency of the modulation signal in the kHz range. To do this, the invention proposes the following method steps:
