Irislens camera

A diaphragm (or iris or iris diaphragm) is a mechanism in a camera that makes a variable aperture to control the intensity of light that passes through the lens. Along with shutter speed, this is what controls the exposure received by the film or image sensor.

A diaphragm may take many forms, from very simple devices for "point-and-shoot" film cameras consisting of just two notched pieces of metal, to more complex ones used in higher-quality cameras which have many blades arranged in a circle. This arrangement, also called an iris by comparison to the corresponding structure in the eye[1] creates a nearly-circular aperture whose size can be varied as needed. There may be as few as 2 blades to as many as 24. In cameras with a small number of diaphragm blades, the shape of the aperture itself (e.g. a hexagon) can often be seen in defocused points of light, or in internal reflections. A lens may deliver a more or less pleasing bokeh with large aperture setting, depending on the aperture's position in the specific lens type's optical path and in most cases also depending on the aperture's roundness.

To transmit a particular light intensity, the physical diameter of the aperture must scale up with increasing lens focal length. Thus, apertures are expressed by the f-stop scale or "F-ratio" which is the focal length divided by the entrance pupil diameter provided by the diaphragm opening. Some professionals prefer to replace the f-stop scales of their equipment with "T-stop" scales which are saying more about the light transmission of the specific lens' glass whilst f-tops are just calculated from geometrical dimensions of the aperture.
