Tiger Optics’ Cavity Ring-Down Spectroscopy (CRDS)  |  Detection at the Speed of Light

Based on absorption spectroscopy, Cavity Ring-Down Spectroscopy (CRDS) works by attuning light rays to the unique molecular fingerprint of the sample species. By measuring the time it takes the light to fade or “ring-down”, you receive an accurate molecular count in milliseconds. The time of light decay, in essence, provides an exact, non-invasive, and rapid means to detect contaminants in the air, in gases, and even in the breath.

A breakthrough discovery by Professor Kevin Lehmann, Ph.D., of Princeton University made the commercialization of this technique possible.  He proved that compact, relatively inexpensive, and widely available Continuous Wave (CW) lasers can substitute for the costly, cumbersome pulsed lasers previously used in CRDS-based research.  He thereby made the requisite power of light affordable and practical for commercial use.


The LAR product portfolio includes water analyzers for the most identifying and monitoring: TOCCODTODBODtoxicityTN, and Oil-in-Water.

With high precision, accuracy, and speed, the LAR analyzers:

  • Optimize and control the measurement process
  • Provides safe supervision of both industrial and municipal wastewater treatment plants
  • Offer a reliable monitoring solution for surface water and inflows of rivers and lakes
