Numerical Aperture

Numerical Aperture is a dimensionless optical parameter that quantifies the light-gathering ability of a lens or optical fiber by defining the range of angles over which light can be accepted or transmitted, determined by the refractive index of the medium and the maximum half-angle of the incident light cone.
