Can be used to rapidly focus the microscope
WebWhen a laser beam is focused to a very small spot by an aberration-free microscope objective (beam concentration), the radius of the spot at the focus (at distance z) is given by the expressions: a(z) = λ. f /πa0. where f is the focal length of the lens. As an example, if a 100x objective having a numerical aperture of 1.3 (producing a focal ...
