Abstract
A gas sensor array includes a housing having a gas measuring chamber. A detector at least partially arranged in the gas measuring chamber measures radiation and generates an output signal as a function of the measured radiation. The detector is arranged on a main axis of the housing. Radiation sources are at least partially arranged in the gas measuring chamber and direct radiation toward the detector. The radiation sources are arranged symmetrically to the main axis at a first focal point and have the same effective radiation path length to the detector. The gas measuring chamber has at least one concave mirror formed by inner walls of the housing. The inner walls form a rotational member produced by a conical section and are configured to bundle the radiation emitted from the radiation source at a second focal point proximate the detector.
