Aperture SNOM





  Scanning Near Field Optical Microscope

 
 
 

The invention and subsequent development of scanning probe microscopy (SPM) methods have produced the necessary tools for a step forward in optical measurements. The possibility to go beyond the Abbe diffraction limit has been achieved with the Near-field light optical microscopes (SNOM or NSOM).

SNOM microscopes employ SPMs precision of piezoelectric raster-scanning together with sharp probes to obtain light optical images at rather better than the usual wavelength-limited resolution.

Particular care has to be taken in the fact that the application of this physical principle to different particular problemsin solid state or biological applications leads to very different technical solutions from a technological point of view.
This is the reason why a universal SNOM instrument does not exist but each one must be tailored with a clear vision of what is going to be the main problem of interest.

For this reason our company collaborates with our customers in order to to give them an instrument which could be as much as possible tuned to their needs.
The isntruments presented here are the result of a collaboration between A.P.E. Research and the INFM, the Italian National Institute for the Physics of Matter.

SNOM microscopes are also equipped with a set of accessories to improve the functionality and increase the range of possible measuraments.
