This note describes a simple and inexpensive device which is being used to observe the temporal and spatial spectroscopic behavior of an exploding wire source. A slotted, rotating disk is used in conjunction with a stigmatic spectrograph to provide broad spectral coverage, spatial information, and good time resolution.
