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.
By closing the iris diaphragm, it closes the peripheral light so you can get a better image.
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.

This iris diaphragm of a microscope contains the amount of light that can enter through to the specimen. If the condenser iris diaphragm is open, the image will be bright; if it is closed, it will be dim.
Cameras have an iris diaphragm.
The radial and circular muscles of the iris.
The iris diaphragm adjusts the amount of light allowed in.
the iris diaphragm controls the amount of light that passes through the stage and, consequently, through the specimen. Reducing the iris diaphragm aperture increases contrast for an image focused under high power by reducing the amount of light that both fills the objective lens and deracts around specimen edges. Opening the iris diaphragm under high magnification increases "flare", the appearance of light "washing out" an object. By decreasing the flow of light through the specimen, the iris diaphragm limits light defraction and saturation.
