The iris diaphragm controls the amount of light entering the camera lens. By adjusting the size of the aperture, it affects the depth of field in the image: a smaller aperture (larger f-stop number) increases depth of field, while a larger aperture (smaller f-stop number) decreases it.
The diaphragm reduces the light from under the stage which can improve the image contrast.
The iris diaphragm controls the amount of light that reaches the specimen, helping to adjust the brightness and contrast of the image. The substage condenser focuses the light onto the specimen, producing a more detailed and sharper image.
The iris diaphragm lever on a microscope controls the amount of light that reaches the specimen being observed. By adjusting the lever, users can increase or decrease the diameter of the diaphragm opening, which helps to enhance contrast and resolution in the image. Proper use of the iris diaphragm is essential for optimizing visibility and detail in microscopic observations.
The iris diaphragm in a microscope controls the amount of light that passes through the specimen. By adjusting the size of the iris opening, you can regulate the brightness and contrast of the image being viewed.
As the diameter of the iris diaphragm increases, the depth of field decreases. A larger diaphragm lets in more light, leading to a shallower depth of field with less of the image in focus. Conversely, a smaller diaphragm increases depth of field by letting in less light and making more of the image appear sharp.
Closing the iris diaphragm reduces the amount of light entering the lens, resulting in a darker image with decreased brightness. However, this reduction in light can potentially improve contrast by reducing any glare or overexposure in the 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 iris diaphragm on a microscope controls the amount of light entering the lens system, helping to adjust the brightness and contrast of the specimen being viewed. By changing the size of the aperture, the iris diaphragm can enhance the resolution and clarity of the image.
The function of an iris diaphragm on a microscope is to adjust the size of the aperture, controlling the amount of light entering the lens system. By changing the diameter of the iris diaphragm, you can adjust the depth of field and improve image contrast and clarity.
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.
