What Does CRDS Stand For?
CRDS stands for Cavity Ring Down Spectroscopy
Cavity Ring Down Spectroscopy (CRDS) is a highly sensitive optical analysis technique used to measure the concentration of trace gases and other substances. It operates by directing a laser light into a high-quality optical cavity, where the light bounces between mirrors. The time it takes for the light intensity to decay, or "ring down," is measured, and this decay time is inversely related to the concentration of the absorbing species within the cavity. CRDS is valued for its precision and ability to detect low concentrations of molecules, making it widely applicable in environmental monitoring, industrial process control, and atmospheric research.
