Paper Abstract

This work shows that the detection limit of transmission IR-microscopy can be dramatically lowered from the regular micrometer-range into the monolayer-range by using a special sample preparation technique. Other than on flat windows, thin organic layers deposited on IR-transparent chalcogenide fibers show a pronounced IR-spectrum when analyzed with a conventional FTIR-microscope in the transmission mode. The layer thickness in the monolayer domain has been calibrated by use of the Langmuir-Blodgett technique with polyglutamates in the range 3.6 to 36 nm. Our experimental results are in accordance with numerical simulations using ray-tracing modelling.
