Abstract

A measuring device for optical and spectroscopic examination of a sample includes a housing, a first light source, a window, an optical spectrometer with a dispersive element and a number of detector elements and which can record light from the first light source which is indirectly reflected by the sample and reenters the housing through the window, an electronic camera whose incidence opening is directed onto the sample, through the window, and an electronic evaluation device which is connected to an image sensor of the camera and to the detector elements. The camera may be assigned a second light source.
