Answered by Aashi6552

Two points that on the axis of an optical system have the property that rays proceeding from one of them will all converge to, or seem to diverge from, the other if the rays fulfill the Abbe sine condition. The two foci of an ellipsoid of revolution are an example of aplanatic points.
