FABRY-PÉROT INTERFEROMETER UNIT, METHOD FOR OPERATING A FABRY-PÉROT INTERFEROMETER UNIT, AND METHOD FOR PRODUCING A FABRY-PÉROT INTERFEROMETER UNIT

摘要

The invention relates to a Fabry-Pérot interferometer unit (100) comprising a first mirror element (102), a second mirror element (104), and at least one plasmonic filter element (112). The first mirror element (102) and the second mirror element (104) are arranged or can be arranged opposite each other in order to form an optical resonator (106) with at least one first light path (108) and a second light path (110). The first light path (108) is paired with a first measurement channel of the Fabry-Pérot interferometer unit (100), and the second light path (110) is paired with a second measurement channel of the Fabry-Pérot interferometer unit (100). The plasmonic filter element (112) is arranged or can be arranged in the first light path (108) and outside of the second light path (110) in order to filter a light beam guided along the first light path (108).
