Abstract

The technical requirements for a small, rugged, and moderately- priced device for measuring fluorescence lifetimes have been investigated. The suitability and performance of various lifetime measuring schemes were compared. Based on these investigations a compact time-domain instrument was developed allowing measurement of fluorescence decays with a time resolution well below 1 ns. A semiconductor laser (frequency-doubled, if necessary) is used as a light source. Detection is done with a miniaturized photomultiplier. In favorable cases measurement of a fluorescent decay curve is accomplished within less than one minute.
