Abstract
A description is given of a simple piezoelectrically scanned Fabry?Perot interferometer based on a commercially available (unscanned) IT-28-30 interferometer. The proposed construction ensures a high thermal stability of the Fabry?Perot resonator because of the mutual compensation of the thermal expansions of the separate elements of the interferometer.
