4.8 Acceptance Angle and Numerical Aperture

The Numerical Aperture (NA) is a measure of how much light can be collected by an optical system such as an optical fibre or a microscope lens.


The NA is related to the acceptance angle a, which indicates the size of a cone of light that can be accepted by the fibre.
