In photography you can use the aperture setting to increase depth of focus. The aperture is an iris-type set up. The smaller the hole through which light passes the greater the depth of focus (in photography we used to say depth of field).
The down side was a smaller hole let in less light so the picture is darker. I guess in a microscope the higher power setting compensates for this.
Don't know if that's any help.
