The iris diaphragm was invented by Joseph Petzval, a Hungarian mathematician, and physicist, in the mid-19th century. Petzval's invention of the iris diaphragm revolutionized photography by allowing photographers to control the amount of light entering the camera lens, leading to better image quality and exposure control.
Cameras have an iris diaphragm.
The iris diaphragm adjusts the amount of light allowed in.
The radial and circular muscles of the iris.
On a microscope, the iris diaphragm controls the amount of light.
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 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 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.
The diaphragm reduces the light from under the stage which can improve the image contrast.
