The objective lens helps adjust the brightness of an image.
The diaphragm reduces the light from under the stage which can improve the image contrast.
The diaphragm reduces the light from under the stage which can improve the image contrast.
Brightness can be changed by changing the voltage to the lamp and adjusting the condenser and diaphragm/pinhole apertures.
Light source and diaphragm. The diaphragm is the opening like and iris in the stage. It can be made large and small like the pupils of the eye.
An iris diaphragm controls the amount of light admitted to a lens. Closing the iris diaphragm will decrease the brightness and increase the contrast of an image.

by closing down the diaphragm
The diaphragm of a microscope is used to control the amount of light passing through the specimen. By adjusting the diaphragm, you can regulate the brightness and contrast of the image, helping to improve visibility and clarity.
