Detector for Spectroscopy

In an embodiment a detector for spectroscopy includes a housing comprises at least one aperture configured for supplying a light beam reflected or emitted from a target, the housing having at least one cross-sectional plane in which the at least one aperture comprises first and second non-contiguous intersecting surfaces, a detector arrangement with a detector surface configured for wavelength- and angle-dependent detection of light, the detector arrangement being arranged in the housing laterally spaced from the at least one aperture, a first reflector element arranged in the housing and a second reflector element opposite the detector surface, wherein the first reflector element is arranged in a beam path of the at least one aperture and is configured to direct a light beam incident through the at least one aperture onto the second reflector element, and wherein the second reflector element is configured to direct an incident light beam onto the detector surface.
