Spectroscopy

Laser spectroscopy is used to detect the composition and concentration of a material by analysing the spectrum produced when it interacts with light.

Laser spectroscopy techniques include Laser Absorption, Frequency Comb, Raman, Photoacoustic, and Ultra-fast, which differ according to the coherence, linewidth, wavelength and power of the laser light and the sample material.

Main application fields are:

• Monitoring of trace gases and water pollutants for the environment.
• Precise and rapid material analysis for applications in biology, medicine, and life sciences.
• Detection of explosives and drugs for security applications.
• Hyperspectral imaging for process monitoring and quality control in industry.
• Lock-in amplifiers, optical spectral analysers, oscilloscopes, monochromators, diffraction gratings, photodetectors.
