How To Calculate Numerical Aperture

Numerical aperture - Wikipedia

https://en.wikipedia.org/wiki/Numerical_aperture

Numerical aperture is commonly used in microscopy to describe the acceptance cone of an objective (and hence its light-gathering ability and resolution ), and in fiber optics, in which it describes the range of angles within which light that is incident on the fiber will be transmitted along it.
