A photoacoustic spectrometer was developed for remote optical absorption measurements in aqueous solutions using an 85‐m optical fiber to deliver pulsed tunable dye laser radiation to a sample cuvette located in a glove box. The spectrometer was tested using aqueous solutions of praseodymium ions. Beer’s law was verified down to a concentration of 8×10−6M for an equivalent absorptance of 3.2×10−5 cm−1.
