How does a LIBS system work?
A high-intensity, pulsed laser beam is focused on the sample area, positioned a few centimeters to a meter from the sample. A single 10 nanosecond-wide laser pulse is all that is needed to excite the sample. When the laser is fired, the high temperature of the laser creates plasma. As the plasma decays or cools (~1.0 µsec after the laser pulse), excited atoms in the plasma emit light of characteristic wavelengths distinct to the element. All elements emit in the 200-980 nm region.
LIBS2500plus systems use up to seven of our HR2000+ high-resolution spectrometers, each with a 2048-element linear CCD array. All spectrometers are triggered to acquire and read out data simultaneously.
