Abstract

Abstract: A lower-cost optically stimulated luminescence (OSL) reader with increased flexibility for pursuing laboratory research into OSL theory and application was designed and constructed. This was achieved by using off-the-shelf optical components and higher-power light emitting diodes. The resulting reader includes more wavelengths of excitation light than current commercial readers, as well as the ability to swap out filters and other components during an experiment. Highlights: Inexpensive flexible reader for optically stimulated luminescent readout was built. High power light emitting diodes with multiple wavelengths used for stimulation. Optical light table enabled easy assembly and adjustment Digital acquisition board with easy programmability simplified project.
