In microscopy, NA is important because it indicates the resolving power of a lens. The size of the finest detail that can be resolved (the resolution ) is proportional to λ / 2NA , where λ is the wavelength of the light. Zobacz więcej In optics, the numerical aperture (NA) of an optical system is a dimensionless number that characterizes the range of angles over which the system can accept or emit light. By incorporating index of refraction in its definition, NA … Zobacz więcej In laser physics, numerical aperture is defined slightly differently. Laser beams spread out as they propagate, but slowly. Far away from … Zobacz więcej • f-number • Launch numerical aperture • Guided ray, optic fibre context • Acceptance angle (solar concentrator), further context Zobacz więcej In most areas of optics, and especially in microscopy, the numerical aperture of an optical system such as an objective lens is defined by Zobacz więcej A multi-mode optical fiber will only propagate light that enters the fiber within a certain range of angles, known as the acceptance cone of the fiber.
