Zusammenfassung:	A stable high‐current transistor‐based regulator has been designed to stabilize 450‐W dc xenon arc lamps. The circuit employs commercially available components. The regulator provides stabilization beyond that found in commercial optical instruments. The improvements using this circuit are a 0.20% ac‐to‐dc regulation representing a 44% decrease in the peak‐to‐peak ac ripple, achievement of nondrifting dc level, and being able to use the spectrometer immediately following lamp ignition.
