Photoacoustic measurement set

The set consists of photoacoustic chambers, light source: Xe 900W lamp and LED, phase-sensitive amplifiers (Lock-in), functional generators. The laboratory equipment enables the measurement of photoacoustic spectra of liquids and solids in the range of 260-800 nm and photoacoustic profilometry. These techniques are used to analyze the spectral and thermal properties of opaque and optically transparent bodies, to monitor the environment (e.g. to determine the efficiency of the photosynthesis process).
