fabry - perot - interferometer - unit, a method for operating a fabry - perot - interferometer - unit and a method for producing a fabry - perot - interferometer - unit

摘要

The invention relates to a fabry - perot - interferometer - unit (100) with 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 opposite one another or be arranged around an optical resonator (106) with at least a first light path (108) and a second light path (110) to form, wherein the first light path (108) a first measuring channel of the fabry - perot - interferometer - unit (100) is assigned and the second light path (110) a second measuring channel of the fabry - perot - interferometer - unit (100) is associated with. The plasmid moni surface filter element (112) is integrated in the first light path (108) and outside of the second light path (110) can be arranged or arranged a along the first light path (108) light beam which is guided to filter.
