Measuring device for optical and spectroscopic examination of a sample

A measuring device for optical and spectroscopic examination of a sample, the device comprising:

• a housing;
• a first light source arranged in the housing;
• a window fitted in a wall of the housing and having a transparent pane which is arranged in such a way that light from the first light source can fall onto a sample arranged outside the housing;
• an optical spectrometer arranged in the housing and having a dispersive element and a number of detector elements which optical spectrometer can record light from the first light source which is indirectly reflected by the sample and re-enters the housing through the window;
• an electronic camera which is arranged in the housing and 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;
• where a second light source is arranged in the housing and is arranged in such a way that light from the second light source can fall onto the sample through the window,
• and where the camera is arranged in such a way that it can record light from the second light source which is reflected by the sample and re-enters the housing through the window.
