Abstract

This work presents the design of a compact USB spectrometer implemented with a cheap microcontroller unit core. A full array detector acquisition in 15ms is reported. The spectrometer is intended to be used along with a microplasma excitation source to provide a portable analytical tool for field studies as well as an educational tool.
