An iris changes the beam size. Just like if you make a circle with your fingers and slowly make it smaller it would let less light through. It will make the beam smaller in the air and on the floor or wall where the light hits. So if you want a tight special on a persons face you could iris it down to there face. it also keeps the circle shape of the beam.
