The numerical aperture of the optical fiber formula is derived above. So this is the formula for NA, where ‘ƞ1’is the refractive index for core & ‘ƞ2’ is the refractive index for the cladding. The numerical aperture value is also important in these equations and higher numerical apertures will also produce higher resolution, as is evident in Table 2. The effect of the wavelength of light on resolution, at a fixed numerical aperture (0.95), is listed in Table 3. 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). The numerical aperture, however, is a completely geometrical measure, which is not considering such aspects.

It is a quick, single number that describes “hey, for a given lens, how well does it gather light from the object we want to see?

The formula is: NA = sin q where NA is Numerical Aperture and q is the half-angle. Numerical Aperture and f-number are related by this equation: f# = 1 / (2 * NA) or NA = 1 / (2 * f#) The numerical aperture provides important relationship between acceptance angle and the refractive index of the core and cladding. These relationships are given here in the image below- Formulas for Numerical Aperture (NA) and Acceptance Angle f/# and Numerical Aperture.

### Since the numerical aperture is a property of the fiber and only depends upon n 1 and n 2, it will not change when the medium outside the fiber changes. The cut-off angle, however, will have to change if the numerical aperture is to be unaffected by a change in n 0: NA = 0.148. sin θ 0max = NA/n 0
