Optical (or light) microscopy is a standard technique for studying microstructure. This microscope can produce micrographs in the magnification range 50-500x, and can use either transmitted light (see through the sample) or reflected light (see the sample surface).
Nikon Optiphot Epi-Fluorescence microscope equipped with polarizing filters, phase contrast and a DS-U1 digital camera. A TransferMan NK2 micromanipulator allows manipulation of samples, such as mounting of AFM colloidal probes, and a Linkam Analysa-LTS350 temperature controlled stage allows study of temperature-induced effects, e.g. lipid phase transitions.
