Spectral Analysis

Through various techniques based on the decomposition of light (prism or diffraction gratings), it becomes possible to analyze the light emitted by a source and go back to its chemical composition.

The experiment presented here propose to use high-tech spectrogoniometers in order to identify precisely the various light rays composing your light source.

We also suggest to make your own monochromator optical table. By adding a CCD array there, then you realize a ""DIY"" spectrophotometer in real time, showing the relative intensities of different rays present in spectral lamps, Mercury or Sodium, for example.
