Microccope Simulator

Stage- A platform on the microscope where the specimen is mounted for examination.
It is in the middle of the microscope and it is very flat. You adjust it by moving the
knob up or down. It is best adjusted while looking in the microscope.

Focus knobs- are used to focus the microscope. They are the knobs in the middle, but
on the side. They are best adjusted while looking into the microscope. You just turn.

Iris- controls the amount of light reaching the specimen. It is located above the
condenser and below the stage. It is used by sliding it either right or left and is
best adjusted looking into the microscope.

Oculars- what you look through at the top of the microscope. There is two, one for
each eye. You slide it left or right and put it on the number that looks right as you are
looking throught the microscope.

Objectives- are the primary optical lenses on a microscope. They range from 4x-100x
and typically, include three, four or five on lens on most microscopes. To adjust you
just turn them around. They are best adjusted while looking at the microscope.
