Light Sources for Gas Analysis

Laser-Driven Light Sources are giving researchers a level of analysis that was not previously possible. Long-path differential optical absorption spectroscopy (LP-DOAS) is used to measure concentrations of trace gases such as ozone and nitrogen dioxide.

Key Benefits of LDLS for Gas Analysis:

• Lifetime an order of magnitude longer than conventional sources such as xenon arc lamps
• Small and very stable plasma discharge spot
• Optically efficient fiber coupling
• High transmission homogeneity
