I believe that it is the diaphragm!
The iris controls the amount of light reaching the retina by adjusting the size of the pupil. In bright light, the iris contracts to make the pupil smaller, reducing the amount of light that enters the eye. In low light, the iris expands to dilate the pupil, allowing more light to enter the eye.
The circular opening of the eye that controls the amount of light entering is called the pupil. It dilates in low light to allow more light to enter and constricts in bright light to reduce the amount of light entering the eye.
The pupil controls the amount of light entering the eye by adjusting its size. In bright light, the pupil constricts to allow less light in, and in dim light, it dilates to allow more light in. This helps to regulate the amount of light reaching the retina for optimal vision.
The Diaphragm or diaphragm control lever regulates the amount of light passing through the slide specimen on the microscope stage.
it controls the amount of light let into the slide.
The pupil controls the amount of light that enters the eye.
Iris controls the amount of light entering into the eye.
The diaphragm, located beneath the stage of the microscope, controls the amount of light passing through the specimen. By adjusting the diaphragm opening, you can regulate the intensity and focus of the light on the specimen to improve visibility and clarity.
SHUTTER in Camera controls the amount and time of light that the Sensor will exposed to.
The diaphragm or iris controls the amount of light that passes through the specimen on a microscope. By adjusting the diaphragm, you can regulate the intensity and focus of the light.

The diaphragm located under the stage of a microscope controls the amount of light that reaches the slide. Adjusting the diaphragm controls the size of the opening and therefore the intensity of the light passing through the slide.
The condenser is the part of the microscope that controls the amount of light reaching the specimen. By adjusting the condenser's aperture and height, you can regulate the amount and focus of light used for illumination in the microscope.
The diaphragm controls the amount of light entering the microscope. It is usually located beneath the stage of the microscope and can be adjusted to regulate the intensity of light passing through the specimen. By opening or closing the diaphragm, you can control the amount of light that reaches the specimen, which can help improve image quality and clarity.
the ISO setting in your camera controls the shutter speed therefore increasing or reducing the amount of light captured by the film/photocell
