INTERFEROMETER ELEMENT, SPECTROMETER AND METHOD FOR OPERATING AN INTERFEROMETER

摘要

The invention relates to an interferometer element (125) for use in a spectrometer (100), wherein: the interferometer element (125) has a micro-mechanical Fabry-Perot filter element (FPI1, FPI2), which has at least one first mirror element (135), a second mirror element (140) and a third mirror element (145) arranged in series on a light path (120) of the interferometer element (125); and a first distance (160) between the first (135) and the second (140) mirror element, and/or a second distance (165) between the second (140) and the third (145) mirror element can be modified.
