The brightness of the light. The optics which direct the light to the slide. The diameter of the objective lens.
Iris diaphragm
So light can pass through the slide to the objective.
The diaphragm on a microscope is there so one can adjust the amount and intensity of light that gets projected up into the slide. The diaphragm is a rotating disk located under the stage. Not all microscopes have one.
For a compound microscope iss; light source, diaphragm, stage, (slide), objective lens, body, eyepiece, eye.
it controls the amount of light let into the slide.
It has different sized holes and is used to vary the intensity and size of the cone of light that is projected into the slide
The diaphram Is What Controls How Much Light Is Released.
A simple device between the light and the slide that controls the amount of light that passes through the object being viewed.

Iris diaphragm
The iris diaphragm controls the amount of light passing through the slide or specimen, while the substage condenser focuses a cone of light on the slice or specimen.
The light views the slide.
