Abstract:
1. A spectrometer for analyzing the optical emission of a sample having: an excitation source, an entrance gap, a dispersive element configured to fan out the spectrum of the light generated in the excitation source in a plane, a plurality of optical solid body sensors, which are arranged in the region of the focal curve of the beam path in order to evaluate the spectral information, wherein the sensors are arranged above or below the plane, and a plurality of mirrors configured to deflect the spectral emission and to focus the spectral emission onto the sensors, wherein the reflecting surfaces of the mirrors are aspherically formed in a direction of curvature, wherein at least one of the sensors is arranged with a sensing component oriented substantially parallel to the plane, and wherein at least one of the mirrors is configured to deflect at least a portion of the spectral emission from the plane, in a direction perpendicular to the plane, onto the sensing component.
