If you place a letter "g" under the microscope, the "g" would be upside down.
Short answer: Zacharias Jansen Long answer: Your question is not valid for 2 reasons: 1. You cannot "discover" something if it does not exist. You should be asking who invented it, not who found it laying around somewhere. 2. A "simple microscope" is not common terminology. Simple compared to an electron microscope? or simple compared to a compound microscope? What is typically referred to as just "microscope" is technically a compound microscope. A set of multiple lenses mounted in a desktop style that allows the compounding of magnification. A compound microscope is the standard microscope in any basic lab setting. Anything more "simple" than a compound microscope would not even really be a microscope, it would either be a telescope, or simpler than that is a magnifying glass (with a single lens) The inventor of the magnifying glass was: Roger Bacon The next step up is the telescope invented by: Zacharias Jansen The next step up is the "compound microscope" which was also invented by: Zacharias Jansen (this is the simplest form of what would be recognized as or named "microscope") If you wanted to go even "simpler" and define microscope as anything that magnifies, there were reading glasses around for thousands of years prior, and even "reading stones" which were lumps of polished glass used to magnify parchment in Egypt as far back as 7000 B.C. (inventor unknown). So it really depends on how you wish to refine your meaning of simple. The magnification of anything? There is no known inventor for reading stones, his name is lost to time. Or if you mean the first invented microscope that could examine things too small for a human eye to detect, that's a compound microscope. Thus if I am guessing your meaning correctly, you meant to ask this question: Question: Who invented the compound microscope? Answer: Zacharias Jansen
You would use the diaphragm and fine-adjustment knob.
Assuming you are asking about a microscope (your question is very unclear on the subject), then the body or barrel of the microscope would do this, it would also be the point at which focus movement would be achieved.
That would be an electron microscope - the magnets are used to deflect the electron beam.That would be an electron microscope - the magnets are used to deflect the electron beam.That would be an electron microscope - the magnets are used to deflect the electron beam.That would be an electron microscope - the magnets are used to deflect the electron beam.

A virus of 50nm would be too small to see unless an electron microscope was used because it has greater resolving power and a resolution up to .1nm. A microscope using compound light as the means of illumination could not resolve better than approx. 200nms.
---- You would use the light microscope. The electron microscope would be unnecessary in this situation, due to its high magnification levels.
An Electron Microscope is used to study the contents of a nucleus.
Ribosomes are very small.So have to use an electron microscope.
You would use an electron microscope to view a Golgi apparatus.
