Abstract

An apparatus and method for manipulating a focus of excitation light on or in a sample, particularly in a microscope. The apparatus has a light source for emitting excitation light, an excitation beam path for guiding the excitation light onto or into the sample, the excitation beam path comprising an objective for guiding the excitation light onto or into the sample and a wavefront modulator for modulating the excitation light, and a control device for driving the wavefront modulator. The control device is designed for driving the wavefront modulator to generate a number of shaped waves on or in the sample. A focus is generated at a specified location on or in the sample by superposition of the shaped waves.
