The diaphragm, often called the "iris" diaphragm for its identical form and function to the iris in your eye, regulates the physical amount of light allowed to pass through a camera lens. It may be called the "iris," the "diaphragm," the "iris diaphragm," the "stop," or the "aperture." All mean the same thing.
Physically, the diaphragm or iris diaphragm is made up of overlapping thin opaque metal plates, usually six or eight, which can be adjusted to increase or decrease the diameter of the hole, called the stop, in the center of the lens. The diaphragm is often located at the optical center of the lens between sets of elements. On manual cameras there is usually a ring around the lens barrel marked in f/stops for adjustment of the diaphragm.
The iris (diaphragm) in your eye, working properly, automatically opens or closes in response to light level. When you are exposed to strong light the iris closes down (or "stops" down) to a smaller diameter, decreasing the light reaching your retina (equivalent to the film or sensor in your camera). In dim light, the iris opens up to admit more light. The diaphragm in your camera works the same way, and on modern cameras it's often equally automatic. You may never even notice it's working.
In a camera, the iris diaphragm and the shutter have to work together to control the total exposure. The iris diaphragm controls the amount of light, and the shutter controls the amount of light over time. Depending on the make and model of the camera, shutter and diaphragm may be manual, automatic or both. The diaphragm is the mechanism that varies the size of the aperture; the opening that allows light into the camera.
Is to stop the passege of light.

If you mean the body organ, the diaphragm will help you to breath out and in. If you mean the type of birth control, it blocks the cervix so the sperm won't get in and cause pregnancy. If you mean a diaphragm in a machine, it is often a membrane, often rubber, that moves back and forth, often for the purpose of pumping things.
