Yes, the microscope is called SNOM. The center idea for it is
to fabricate a very small excitation light spot.
The disadvantage for it is that it only works dry in air and is
only good for 2-D imaging.
I spent a lot of time on electronics and DAQ softwares to make it
work. And am looking for some interesting samples to look at.
please give me some advice. the more the merrier :)
