Numerical aperture (NA) refers to the cone of light that is made from a focusing lens and describes the light gathering capability of the lens (similar to f/# ). NA is defined by the following equation, where n is the index of refraction of the medium (often n=1 for air), and α is the half angle of the cone of light exiting the lens pupil. Collecting Light: The Importance of Numerical Aperture in Microscopy. Numerical aperture (abbreviated as ‘NA’) is an important consideration when trying to distinguish detail in a specimen viewed down the microscope. NA is a number without units and is related to the angles of light which are collected by a lens.

Building a Setup?

Many authors substitute the variable α for µ in the numerical aperture equation. Numerical Aperture (N.A.): This is a number that expresses the ability of a lens to resolve fine detail in an object being observed. It is derived by a mathematical formula ( n sine u ) and is related to the angular aperture of the lens and the index of refraction of the medium found between the lens and the specimen. Numerical Aperture Definition A numerical aperture is defined as a unitless and dimensionless number that describes the range of angles that a lens can emit or accepts lights. Can numerical aperture be negative? A numerical aperture can not be negative in the sense that an aperture cannot accept or emit a negative amount of light.
