Abstract: A hand-held spectrometer includes at least one indicator light and a processor configured to control the at least one indicator light to indicate a state of the hand-held spectrometer selected from a group consisting of a background scanning state, a ready-to-scan-sample state, a signal strength state, a fluorescence intensity state, a sample match state, a sample classification state, an error state, a data transfer state, a battery charge state, and a memory capacity state. The sample match state can be, for example, one of a positive match state, a mixture match state, a negative match state, and a match error state. In some embodiments, the error state can be at least one of a background error state, a user error state, and an instrument error state, or any combination thereof.
