The iris diaphragm is named after the iris, the colored part of the eye, because of its similar appearance and function. Just like the iris controls the amount of light entering the eye, the iris diaphragm in a camera lens controls the amount of light entering the camera.
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.
The diaphragm reduces the light from under the stage which can improve the image contrast.
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 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 iris diaphragm is named after the iris, the colored part of the eye, because of its similar appearance and function. Just like the iris controls the amount of light entering the eye, the iris diaphragm in a camera lens controls the amount of light entering the camera.
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.
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.

The pigmented diaphragm of the eye is the iris, which is the colored part of the eye. It controls the size of the pupil, which regulates the amount of light entering the eye. The pigmentation of the iris determines a person's eye color.
