Abstract
The construction and use of a high-speed mechanical chopper wheel, compatible with the frequency ranges of most lock-in detectors, is described. The chopper, consisting of an air turbine handpiece and multihole disk, can span the region from 500 Hz to 300 kHz with a single blade change. This device is particularly suited to modulated laser spectroscopy.
