Abstract
A laser absorption spectrometry system for gas measurement is provided. The system includes an integrated cavity output spectroscopy (ICOS) assembly including a gas cell. The gas cell includes a cell body defining an optical cavity and an input mirror and an output mirror positioned in the optical cavity. The assembly further includes a tunable diode laser configured to emit laser light, a collimator positioned in an optical path between the tunable diode laser and the gas cell, and a detector arranged to measure laser light exiting the optical cavity. The collimator includes at least one of a reflective collimation mirror or a gradient index (GRN) lens.
