For Lab, Forensic, Environmental, Defense and Industrial LIBS
DUNEDIN, Fla., Feb. 22, 2007 -- The LIBS2500, the next-generation laser-induced breakdown spectroscopy (LIBS) system from optical sensing solutions provider Ocean Optics, takes LIBS technology to the next level, permitting instant qualitative measurements of elements in solids, solutions and gases for use in materials analysis, biomedical and forensic analysis, environmental monitoring, art restoration and security and defense.

Designed to be smaller and lighter than its predecessor, the LIBS2000, the slimmed down system features an improved sensitivity of 10-50 ppm, a series of 2048-element, linear CCD detectors and a seven-fiber optical sampling probe with a 74-UV collimating lens and a sampling lens.

LIBS2500.jpgTraditional LIBS systems typically operate over a small spectral range. In contrast, the LIBS2500 incorporates up to seven high-resolution spectrometers for spectral coverage as broad as 200-980 nm. The system operates with any 32-bit, USB-compatible Windows PC over a USB 1.1 or 2.0 interface.

Integral application software fires the laser and identifies the element being analyzed, also performing reference correlation by full pixel, reference correlation by spectral line, time-dependent analysis and line tracking over multiple samples.

In addition, it allows the user to control the exact time of sampling during plasma decay and operates on "method saving" to set and perform procedures for an entire sample test. Elemental identification and correlation software provides instant material identification and a spectral library consisting of 2000+ atomic emission lines from the US National Institute of Standards and Technology (NIST), the company said.

The streamlined LIBS2500 detection system is portable, compact and rugged. Users can perform in situ real-time measurements in hostile industrial, chemical and biochemical environments.

Ocean Optics said the accessories required to complete the LIBS2500 system have also been upgraded. The redesigned LIBS imaging module, which comes with PixeLINK software, allows users to precisely adjust the laser to focus on the region of interest of the test piece.

The new LIBS sample chamber (LIBS-SC) includes a manual X-Y-Z stage. The inside lens and spectrometer-probe mounting hardware are reconfigurable, with additional components readily available. The sample chamber also includes a laser safety cutoff switch, along with a blower and evacuation system to feed in alternate gases such as argon.

GLOSSARY
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
plasma
A gas made up of electrons and ions.
spectrometer
A kind of spectrograph in which some form of detector, other than a photographic film, is used to measure the distribution of radiation in a particular wavelength region.
