Paper Abstract

Microoptic probes for gas absorption-measurement making use of single mode optical fibers and graded-index microlenses are considered. A model for a potentially rugged and low- cost probe is given, which minimizes the optical alignment problems, as well as offering intrinsic-loss less than 3 dB for absorption path-lengths up 20 cm, and less than 10 dB when path-lengths up to 40 cm are considered. Probe tests on a breadboard assembly are presented, together with the implementation of two demonstrator probes for methane alarm measurements.
