Photoacoustic measurement set
Two lock-in based photoacoustics sets are available. The first one, photoacoustic spectrometer, allows for the spectral characterization (260-800 nm) of condensed materials. The second one, photoacoustic profilometer, allows for the thermal characterization of samples. The profilometer is now extended into two-multibeam mode, allowing for the monitoring of two distinct pigment sites. Sample excitation by LED sources, currently available 280, 360, 430 and 520 and 650 nm.
