Abstract: A spectrometer for examining the spectrum of an optical emission source may include: an optical base body, a light entry aperture connected to the optical base body to couple light into the spectrometer, at least one dispersion element to receive the light as a beam of rays and generate a spectrum, and at least one detector for measuring the generated spectrum. A light path may run from the light entry aperture to the detector. A mirror group with at least two mirrors may be provided in a section of the light path between the light entry aperture and the at least one detector, in which the beam does not run parallel, which may compensate for temperature effects. In the mirror group, at least one mirror or the entire mirror group may be moveable relative to the optical base body and may be coupled to a temperature-controlled drive.

Abstract: A spectrometer may include a radiation source having a spark generator, an entrance slit, a dispersive element and a plurality of detectors, and a rotatable sector shutter having an axis of rotation and a trigger unit optically coupled to the sector diaphragm. The axis of rotation of the sector shutter is non-parallel to a connecting line between the source and the entrance slit.

Abstract: An arrangement for optical emission spectrometry with a spectrochemical source, which during operation emits non-directed radiation, and with a spectrometer having at least one entry aperture arranged at a side next to the source, at least one dispersive element and at least one detector, which are arranged such that during operation part of the radiation emitted in the direction of the entry aperture from the source enters the spectrometer through the entry aperture, from the entry aperture falls indirectly or directly on the dispersive element(s), is split up according to wavelengths and is registered by the at least one detector. A mirror may be arranged at a side of the source opposed to the entry aperture at a distance from the source to reflect at least one part of the radiation, not emitted in the direction of the entry aperture from the source, in the direction of the entry aperture.
