LIBS- Laser Induced Breakdown Spectroscopy

Description

The LIBS2500plus Laser-induced Breakdown Spectrometer Measurement Systems are detection systems that permit real-time qualitative measurements of elements in solids, solutions and gases. These broadband, high-resolution systems provide spectral analysis across a wide 200-980 nm range (depending on the system) at a resolution of ~0.1 nm (FWHM).
