This calc converts between them, and also gives the angle (α) of collection for the lens. The f-number is defined in air, but for the NA, refractive index is taken into account if necessary. The f/# and NA are calculated from the aperture size (or Gaussian 1/e² beam width) and the focal length in air. Known ratios, together with the light wavelength, allow spot size calculations. This calc is accurate to ~2 significant figures. NA / f-number converter: Numerical aperture: f-number: www.ibsen.com The numerical aperture (NA) of the fiber is the sine of that maximum angle of an incident ray with respect to the fiber axis. It can be calculated from the refractive index difference between core and cladding, more precisely with the following relation: 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/# ).

It can often be easier to talk about the overall light throughput as the cone angle, or the numerical aperture (NA), of a lens. The NA of a lens is defined as the sine of the angle made by the marginal ray and optical axis in image space, shown in Figure 1.

This calc converts between them, and also gives the angle (α) of collection for the lens. The f-number is defined in air, but for the NA, refractive index is taken into account if necessary. Acceptance Angle & N.A. Calculator Your source for Fiber Optics, Fiber Optic Lighting and Illumination products since 1977 Manufacturing Standard and Custom fiber optics for Industrial, Medical, Commercial, Military and Machine Vision applications since 1977. Use our Excel Numerical aperture calculator. Many people believe that using a low N.A. fiber will “focus” the light from a source. This is not true.

This calc converts between them, and also gives the angle (α) of collection for the lens. The f-number is defined in air, but for the NA, refractive index is taken into account if necessary. You can use this calculator to identify the numerical aperture and the acceptance angle of any glass combination. N1 is always larger than N2. Therefore, if your result is "0", you have reversed the values. For a Gaussian beam (as opposed to a homogemeous beam), the "Aperture diameter" is the 1/e² diameter, and a large lens size is assumed.
