Abstract

Imaging device to detect electromagnetic radiation, which is preferably fluorescence-emission, wherein a collection unit collects the electromagnetic radiation and transmits it to a sensor device, wherein the sensor device is a photomultiplier array, preferably a silicon photomultiplier array, and the collection unit comprises a multichannel optical waveguide in the form of a mi-crostructured fiber, comprising at least two solid cores separated by at least one hollow tube, wherein in each solid core propagates a portion of the collected electromagnetic radiation and wherein the emitted portion of electromagnetic radiation of each individual solid core is projected by a projection-/ magnification unit on an individual pixel of the photomultiplier array.
