Laser Induced Breakdown Spectoscopy

Laser Induced
Breakdown Spectroscopy or LIBS has become the common acronym for element
detection using laser plasma. This permits real-time qualitative identification
of trace elements in solids, gases, and liquids using optical detection of
elemental emission spectra. Using this technique, little or no sample
preparation is required and calibration-free quantitative analysis is possible
without matrix effects.
The SpectraWiz software
provides element identification via spectral database for qualitative
measurements. Samples are quickly measured and saved to a text log-file.
Compound element libraries can be created and searched. Customizable programs
are also included to operate directly from Excel+VBA and LabVIEW.

RED-Wave
NIR InGaAs 1024 Spectrometers
 StellarNet has announced high performance NIR spectrometers for the 0.9-2.2um
range with optics that have no moving parts. The TE cooled detectors are InGaAs photo
diode arrays with 1024 pixels, each 25um wide and 500um tall. Extended range detectors for
1.4-2.2um are 250um tall. The RED-Wave NIR-InGaAs are miniature fiber optic spectrometers
used for lab and portable applications. Several models provide various operational ranges
and optical resolutions (from 4nm down to 0.2nm) suitable for both spectroscopy and
optical spectrum analysis.
A 2.5 MHz digitizer delivers NIR spectra in 1ms via high speed parallel or USB-2
interface. SpectraWiz software includes spectroscopy measurements for transmission,
reflectance, absorption, and spectroradiometry. Additonal programs are provided for
LabVIEW, VC, VBA-Excel, and Delphi for cusomization. Applications include thin-film
measurements, moisture analysis, tunable laser characterization, and optical power
monitoring.
The portable spectrometers are packaged in small rugged enclosures with SMA905 fiber
optic input, and attach directly to high speed IEEE1284 parallel or USB-2 ports. Numerous
models provide variety of operational ranges for UV-VIS-NIR (up to 2200nm) with optical
resolutions (down to 0.1nm) suitable for spectroscopy (chemical and optical analysis,
radiometry, colorimetry), optical spectrum analysis, process control & monitoring, and
remote sensing.
The spectrometers include the multi-application SpectraWiz software with drivers and
sample code for LabVIEW, VC, VBA and Delphi under Win9x/Me /NT /2000 /XP. Surf
