Confocal Microscopy

Confocal laser microscopy is an experimental technique providing with high-resolution in-focus optical images, which are acquired in raster-mode (i.e. point-by-point) and reconstructed with a computer.

Our laboratory is equipped with modern 3D scanning confocal microscope with spectrometer "Nanofinder-S", which is used to perform studies with submicrometer resolution (about 250-500 nm) of solid bulk materials, thin films, nanopowders, solutions, etc.

The system allows to conduct simultaneous and multifunctional analysis by optical and confocal microscopy; Raman and luminescence spectroscopy; 0D, 1D, 2D and 3D high-speed imaging with spectroscopy.
