EasyLIBS IVEA Laser Induced Breakdown Spectroscopy (LIBS)
Portable EasyLIBS IVEA system (model Easy 2C) employs a pulsed Nd:YAG laser, with the possibility to dual pulse mode, and emits at the fundamental wavelength of 1064 nm. The laser energy per pulse on the sample is higher than 25 mJ with a repetition rate of 1 Hz and the duration of laser pulse is 4-5 ns. The Easy 2C model consists of an optic probe in form of gun that allows focusing the laser in the material to analyze. The gun goes connected to a computer and to three spectrometers, one corresponding to the Ultraviolet (UV) spectral range (196-419 nm), Visible (419-580 nm) and that of the near Infrared (NIR) (580-1000 nm) (Czerny-Turner Ocean Optics HR 2000+). The optical resolution is 0.2 nm (Full Width at Half Maximum, FWHM) (spectral resolution of about 1000). A CCD detector collects the signal. The software used for automatic acquisition, control, visualization and processing of the spectra is the AnaLIBS version 6.3.
