Multiplexed NIR-Spectrometer, Multispectral and Hyperspectral NIR spectrometer, NIR Spectrometer, Echelle Spectrometer

The Echelle spectrometer / Spectrograph ESA 4000 is a spectral high resolution, compact measurement device with active and passive coupling on different radiation sources in atom spectroscopy. In a wavelength range of 190 to 780 nm and with a resolution of a few picometers spectra are recorded by an ICCD camera. With a new electronic unit and a new camera board ESA 4000 is the successor of the Echelle spectrometer ESA 3000.

For analytical applications in atom spectroscopy, the relevant atom lines of the elements need to be assessed quantitatively. Complex materials are characterised by a large number of atom lines, which interfere in case of insufficient spectral resolution. Often exaltation of the atom lines is a dynamic process, requiring time resolved recording of the spectral lines. The resulting requirement is simultaneous recording of an as large as possible spectral range with a resolution of a few picometers, which is achieved by an Echelle spectrograph with ICCD camera. The optional integration of an image intensifier further increases the light sensitivity and performs as an optical shutter with up to a few nanoseconds exposure time. This configuration permits time correlated measurements or decay measurements. Control of external radiation sources, e. g. of lasers, as well as to that control time correlated measurement of secondary light radiation, qualify the spectrometer ESA 4000 for the Laser Induced Breakdown Spectroscopy (LIBS) and for applications for simultaneous multi-element analysis.
