Abstract: The present disclosure relates to a measuring system for measuring a light source in a polarization-independent manner, having a camera comprising a plurality of image sensors arranged in the form of a matrix, and a microscope optics, and to a method for measuring the light sources in a polarization-independent manner. The aim is to make it possible to measure the light output of the light source in an improved, simple and largely polarization-independent manner while maintaining the spatial resolution in the microscopic range. To that end, the present disclosure proposes that a linear polarizer is associated with each of the image sensors, wherein the linear polarizers are arranged in the form of a matrix in front of the image sensors and two or more, preferably four, polarizers form a matrix block, wherein the transmission directions of adjacent linear polarizers within a matrix block are rotated relative to one another, preferably by 45° or by 90°.
