Introduction
Product Overview
The Ocean Optics LIBS2000+ Laser-induced Breakdown Spectrometer is a detection system that permits
real-time, qualitative measurements of trace elements. This broadband, high-resolution instrument allows
for spectral analysis from 200-980 nm, with resolution of ~0.1 nm (FWHM). Sensitivity has been
reported to parts-per-billion and picogram levels.
The LIBS2000+ comes in a standard 3U rack case with handles for extra convenience. The LIBS2000+
operates with any 32-bit, USB-compatible Windows PC. We provide OOILIBS Application Software
with spectral-saving and data-logging capabilities for operating the LIBS2000+ and for firing the laser.
Correlation Software, developed with the University of Florida, provides instant material identification
when using the LIBS2000+ and a spectral library consisting of 2500 atomic emission lines from the NIST
(National Institute of Standards and Technology) tables for elemental identification.
The LIBS Imaging Module is available for use with the LIBS system to enable you to precisely adjust the
laser to focus on the exact spot on the sample that you wish to analyze. The LIBS Imaging Module also
comes with PixeLINK™ software for the camera to capture high quality images on your PC.
How the LIBS2000+ Works
A high-intensity, 10 nanosecond-wide laser pulse beam is focused on the
sample area. When the laser is fired, the high temperature of the laser ablates
the surface of the sample and creates plasma. As the plasma decays or cools,
excited atoms in the plasma emit light of characteristic wavelengths distinct to
the elements present. All elements have emission spectra in the 200-980 nm
region. The detection system uses seven of our HR2000 High-resolution
Miniature Fiber Optic Spectrometers, each with a 2048-element linear CCD
array. All spectrometers are triggered to acquire and read out data
simultaneously. The detectors in the broadband (200-980 nm) LIBS2000+
collect the signal; software included with the system displays and identifies the
emission spectrum.
Advantages of Broadband LIBS Techniques
Many LIBS systems have a small spectral range. The LIBS2000+ is the first to provide broadband
spectral analysis. Because the system is noninvasive, you can perform real-time measurements in situ, in
hostile industrial, chemical and biochemical environments with little or no sample preparation.
