Abstract

The planar optical structure forms an evanescent-field measuring platform. A body is made from the thermoplastic plastic with a three-dimensionally structured surface, wherein molding is performed directly from a master made of glass coated with metal oxide, without deposition of further coatings on a surface of the master. The planar optical structure forming an evanescent-field measuring platform has a first essentially optically transparent, waveguiding layer (a) with a refractive index n1 and a second essentially optical transparent layer (b) with refractive index n2, where n1>n2, in a case of an embodiment of a planar optical film waveguide, or a metal layer (a′) and a second layer (b), in a case of an embodiment for generating a surface plasmon resonance, wherein the second layer (b) includes a material from a group of cyclo-olefin polymers and cyclo-olefin copolymers.
