We have developed a UV-Visible photoacoustic spectrophotometer using relatively inexpensive individual optical components. The instrument was initially developed due to the absence of a commercial photoacoustic instrument in the UV-Visible range. We have found that this custom built instrument allows numerous software generated options that are unavailable on any commercial spectrometric instruments. In addition to recording routine intensity versus wavelength spectra, we can record the following: 1) resolution of the spectra in layered samples; 2) quantitative depth profiles in samples; 3) spectra and spectral fragments can be smoothed and joined into continuous spectra; and 4) signal averaging of spectra can be carried out. The construction of this custom built instrument allowed the maximum flexibility in experimental application with minimum cost to the investigator. |
