ABSTRACT:
A gas sensor arrangement comprises a first half-shell mateable with a second half-shell. The first half-shell has a detector receiving opening and radiation source receiving apertures. A gas measuring chamber is formed between the first half-shell and the second half-shell. The gas measuring chamber extends between the detector receiving opening and the radiation source receiving apertures. Concave mirrors are arranged around the radiation source receiving apertures. The concave mirrors are formed by inner surfaces of the first and second half-shells. Tubes extend from the concave mirrors to the detector receiving opening. The tubes are formed by the inner surfaces of the first and second half-shells. The inner surfaces are coated with a reflective material.
