When the lens and image planes are not parallel, adjusting focus rotates the PoF rather than merely displacing it along the lens axis. The axis of rotation is the intersection of the lens's front focal plane and a plane through the center of the lens parallel to the image plane, as shown in Figure 3. As the image plane is moved from IP1 to IP2, the PoF rotates about the axis G from position PoF1 to position PoF2; the "Scheimpflug line" moves from position S1 to position S2. T… WebThe term depth of focus is sometimes also used in the context of laser beams.It is essentially the same meaning, but for a quantitative measure it is then more appropriate to use the Rayleigh length (for Gaussian beam) …
