System for spectral analysis by means of laser emission of halogen especially chlorine

摘要

The analysis system uses a pulsed laser (L) and a laser beam (P), which is aligned on the non metallic or partly material (T). An optically focussing unit (LE), guides and concentrates the light emitted from the plasma (PA) to the gap (SL) of a spectrometer (SP). A matrix type camera unit (BA, fig.2), with which the intensity of the slice volume (V) of the emitted light, imaged across the spectrometer gap (SL). Spectrally triggered and is summated in time and space after passage through the spectrometer (SP), using an image storage and an evaluation unit (BS or DM). A control unit (SC) is arranged between the laser (L), the spectrometer (SP), the camera (BA) and the image storage and evaluation unit (BS and DM), for the time interval corrected storage and analysis of the spectral signals of the emitted light.
