Patent ID: 11933956
Assignee: CARL ZEISS MICROSCOPY GMBH
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 6:
7. A microscope comprising:
a first light source configured for outputting light of at least one first wavelength (λ.sub.photo) to illuminate a sample plane and a sample that is arranged therein along an illumination beam path;
a second light source configured for outputting light of at least one second wavelength (λ.sub.exc) to illuminate the sample plane;
a diffraction grating disposed in the illumination beam path between the first and second light sources and a sample plane, wherein light of the first wavelength (λ.sub.photo) is not diffracted by the diffraction grating and light of the second wavelength (λ.sub.exc) is diffracted due to the diffraction grating; and
a detector configured for detection of light emitted from the sample in response to the light of the at least one second wavelength that illuminates the sample plane.
