Abstract

A single-beam photothermal-lensing technique to study interfaces is presented. By analysis of the reflection from a quartz–solution interface with a low-power laser in a single-beam configuration, a photothermal signal is detected. The data were fitted with a conventional thermal lens model, and the results show that the optical element formed at the interface resembles an inverted thermal lens.

  11. A change in the TL signal as a function of the pinhole position with respect to the spot beam is expected because the integrated signal is invariant. In our system when we moved the detector toward the reflected beam edge, a decrease in the magnitude of the TL signal that tends to zero in the beam periphery was observed, but the expected signal inversion was lacking. (It is important to mention that for this purpose the sample was placed at +3Zc.) This lack of inversion is probably due to the relatively low magnitude of the TL signal. (In our configuration the amount of reflected light is only ∼4% of the incident beam.) In other words, inversion is not observed owing to sensitivity reasons.

  13. The optical element formed at the interface has a positive focal distance (converging lens), thus an inverted signal as compared with conventional TL assays. We believe that the inverted focal distance of the thermo-optical element is a characteristic of the interface where it is formed. We are currently working on mathematical models to quantify this effect.
