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.Keywords
