Abstract: A light source (112) for generating illumination light for illuminating at least one sample is disclosed. The light source (112) comprises



at least one array of light emitters (114), wherein each of the light emitters (114) is configured for emitting at least one light beam along a light beam path, wherein the light beam has a predefined wavelength range, and
at least one reflective optical grating (116) configured for overlaying the light beam paths, at least one transfer element (118);

wherein the transfer element (118) is arranged between the array of light emitters (114) and the optical grating (116) such that the transfer element (118) directs the emitted light beams onto the optical grating (116) and provides the light beams reflected from the optical grating (116) and impinging on the transfer element (118) into at least one measurement channel (120), wherein the measurement channel (120) is configured for receiving at least one sample.

Abstract: An optical system configured for Fourier Ptychography is disclosed, comprising at least one array of light emitters, wherein each light emitter is configured for emitting at least one illumination light beam towards a sample plane; at least one lenslet array comprising a plurality of lenses, wherein each of the lenses is dedicated to at least one of the light emitters of the array of light emitters, wherein orientation and shape of the respective lens is adapted to the dedicated light emitter, wherein the lenslet array is configured for focusing the illumination light beams in the sample plane. The array of light emitters and the lenslet array are arranged such that the sample plane is illuminated by the illumination light beams under different illumination angles.
