This unique configuration extends the conventional scanning range to 200x200 um.

In this configuration scanning is carried out by the sample. It allows to reach maximal resolution and minimal distortions.

STM head with preamplifier (30pA-50nA). Open configuration allows easy access to sample-tip area for high aperture laser illumination, etc. Scanning by the sample allows to reach maximal resolution.

This configuration may be used for investigation of cellular creations, molecule of DNA, viruses , property of semiconductors , for obtaining structures with characteristic scale about 1/10 wavelength , for realization of spectroscopy of biological object (as a rule with help of UV radiation) , for observation of process of chemical reaction.
