WebDue to Snell's law, the numerical aperture remains the same: 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 has the property that it is constant for a beam as ... Web4 de ago. de 2024 · It also should now make clear why a high f-number corresponds with small aperture, and a low f-number corresponds with a wide aperture. That same 50mm lens set to f/22, for example, only has an entrance pupil diameter of around 2.27mm – far smaller than the 25mm measured at f/2. So, quite literally, it’s all in the maths.
