FacilitiesThin Film Laboratory - UdR ParmaDouble Langmuir Blodgett Instrument model KSV 5000: acomputer controlled and programmable Langmuir-Blodgettinstrument for the study of monolayers at the air-water interfaceas well as for the automated Langmuir film experiments anddeposition of normal or alternating multilayers onto solidsubstrates. The LB Instrument is equipped with a set of speciallydesigned and home-made troughs e.g. for limited amount ofcompounds, such as proteins or lipids, Langmuir Schaeferdeposition with proper sectioning of the area of every filmtransfer, thermal control of the subphase.Optical near field scanning microscope, produced by APEresearch and modified to perform polarization analysis, alsoin polarization modulation for optical axis determination e.g.in liquid crystalline media. Three signals can be acquiredsimultaneously (e.g. scattered, and 2 polarizations oftransmitted light) by a multiplexing system developed adhoc. It can be operated with different wavelengths. Suitablefor measuring in pump-probe configuration. The microscopecan be coupled to a LN2 cooled CCD spectrometer (JY TRIAX320), for fluorescence measurements. A suitable softwarehas been developed to perform optical nano-lithography.Null-ellipsometer with very high angular resolution (
