The application of photothermal interferometry and near-field thermal lensing as analytical tools in liquids is described. Using the transverse setup, the smallest detection volumes are achieved. The setups of both sensor systems are miniaturized, so adjustment and external influences are minimized. The sensitivities of both systems are demonstrated with the textile dye Reactive Red as an analyte.
