a:  electron microscope ~
b:  upside-down light microscope
What:  
"The electron microscope is like an upside-down light microscope. The
radiation enters at top and the specimen is viewed at the bottom. The
principle is the same as in a light microscope in that a beam of radiation
is focused by condenser lenses through the specimen, and then the
image is magnified by further lenses."
