Concept information
PREFERRED TERM
off-axis integrated cavity output spectrometer
DEFINITION
- Instrument that determines the mixing ratio of an analyte by the optical extinction of laser light of a specific wavelength in a high-finesse optical cavity consisting of two highly reflective mirrors. The optical extinction is caused by scattering or absorption by the analyte. The continuous-wave laser is coupled in an off-axis configuration with respect to the optical cavity.
