Abstract
The invention relates to a spectrometer for analyzing the optical emission of a sample, having an excitation source, an entrance gap and a dispersive element, which fans out the spectrum of the light generated in the excitation source in a plane, and having solid body sensors with one or more lines, 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 the spectral emission is deflected onto the sensors by mirrors and focused, wherein the reflecting surface of the mirrors is aspherically formed in a direction of curvature.
