Abstract:
The invention relates to a device for analysing materials by plasma spectroscopy, of the type that is portable and self-contained and including a housing (10) containing a laser generator (18) generating laser pulses that are focalised onto the surface of a material to be analysed by a parabolic mirror (32) capable of translation in the housing so as to carry out a series of point measurements along a scanning line at the surface of the material to be analysed and a measurement on a calibration sample (50) mounted in the measurement endpiece (22) of the housing (10).
