Webbspot of diameter d0. How big is the focal spot? Well, of course this depends on how we define the size of the focal spot. If we define it as the circle which contains 86% of the energy, then d0= 2w 0. Then, if we assume that the input beam completely fills the lens (so that its diameter is D), we find: 0 2 2 # f d f D WebbDive into the research topics of 'Small focal spot formation by vector beams'.
