what do the illuminator do
it illuminates light
what are objective lens
objective lens is the lower lens near the specimen which makes the specimen look bigger or smaller

Scanning electron microscope
what does nose piece do
it changes the types of objective lens
what does coarse adjustment do
it moves the stage closer or farther from the objectives
what does the eye piece do
you look into the eye piece and it magnifies by 10x

Normally it is mounted on a transparent glass slide between the condenser lens and objective lens.
How do you get the magnification by the naked eye
ocular lens times magnification of objective
