Numerical Aperture 2. Acceptance Angl This video describes, What is Acceptance Angle, Acceptance Cone with Diagram and also what is Numerical Aperture (NA), relation between numerical aperture an Numerical Methods In Lens (A) Lens Formula Definition: The equation relating the object distance (u), the image distance (v) and the focal length (f) of the lens is called the lens formula. Assumptions made: The lens is thin. The lens has a small aperture.

This movement opens and closes the iris diaphragm inside. Acceptance angle or Numerical aperture Let us consider an optical fibre having a core with refractive index n1 and cladding with refractive index n2 such that (n1 > n2). The refractive index of the launching medium is n 0. Let us consider a light ray AO enters the fiber making an angle qi with its axis. Another way to look at this is by the concept of numerical aperture (NA), which is a measure of the maximum acceptance angle at which a lens will take light and still contain it within the lens. Figure \(\PageIndex{1b}\) shows a lens and an object at point P . The numerical aperture can be expressed and determined by the following formula: Numerical Aperture (NA) = n • sin (α) In the above equation, ‘n’ is the refractive index of the medium between the cover glass and the front lens of the objective (for example; air, water or oil).
