摘要

High resolution imaging method for capturing a test substance in a test medium by interacting the test substance and a reference substance bounded to a solid-phase, comprises subjecting the test medium to a solid phase, at whose surface a film is arranged with the reference substance, capturing optical changes emerged by the interaction of the reference- and test substance by an ellipsometer, and optionally comparing the changes with a standard sample, where the ellipsometer is supplied with a brilliant infrared-light source in an average infrared spectral area (400-4000 cm-1). An independent claim is included for a measuring apparatus for the execution of the above procedure, comprising an ellipsometer, which shows a radiation source, a polarizer, an analyzer, a detector and an evaluator, and a solid phase, at whose surface a film with a reference substance and a test substance adhered to the reference substance are arranged, where the radiation source is a brilliant infra-red light source.
