Abstract
An illumination apparatus for illuminating a sample plane and a sample that is optionally arranged therein along an illumination beam path includes: a first light source (for outputting light of at least one first wavelength (λ), a second light source for outputting light of at least one second wavelength (λ), and a diffraction grating in the illumination beam path between the first and second light sources and the sample plane. Light of the first wavelength (λ) is not diffracted by the diffraction grating, and light of the second wavelength (λ) is diffracted due to the effect of the diffraction grating. The illumination apparatus can be used in a microscope.
