A windowless resonant photoacoustic chamber is described for environmental and agricultural applications. The windowless design is a solution to the lack of perfect windows in the infrared region. The design was made insensitive to external noise with the help of acoustic filters. The chamber was designed to have a high quality factor of about 400. Experimental results show good agreement with the theoretical calculations.
