A natural optical system that has a diaphragm and an aperture is the human eye. The iris is the diaphragm, the pupil is the aperture. In the human eye, the iris can both constrict and dilate, which varies the size of the pupil. Unsurprisingly, a photographic lens with the ability to continuously vary the size of its aperture (the hole in the middle of the annular structure) is known as an iris diaphragm.
