Abstract:
A photoacoustic detector includes a sensing region for receiving atmospheric samples. Radiant energy from a source is directed toward the sensing region. A thermal isolator and a displaced optical filter are positioned between the incoming radiant energy and the sensing region so that the radiant energy passes, at least in part, through both elements.
