For example, since the rays from the sun are effectively parallel, a magnifying glass can be used to produce an intense spot at a distance equal to the focal length.<br /> <br /> For a diverging (concave) lens, the focus is virtual : it is the distance ''behind'' the lens from which incident parallel light appears to emanate.<br /> <br /> =See Also=<br /> * [[Diopters]]</div>
