optical microscope at 0.5 nanometer using  active imaging
(automatic moving slide into a tiny region of imaging to correct imperfections in
the placement of silicon atoms in the CCD of the pixels.  This corrects changes
in electrons due to hitting Si at difft angles...  used for imaging fuorescent labeled
samples.
 
Can see distances in multi-domain proteins like human RNA polymerase II,
which initiates DNA transcription.</p>
