Abstract

We describe the construction and performance of a self-contained, battery-operated, hand-held optical spectrometer. This unit contains an onboard optical excitation source, miniaturized monochromator, CCD detector, Peltier cooler, LCD display module, and microprocessor control. We demonstrate capabilities for qualitative fluorescence determinations and semiquantitative fluorescence and absorption measurements. Resolution is λ/δλ ≍ 1200 at 434 nm.
