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. For a truncated beam, the appropriate spot size ratio should be applied (see the relevant calc, e.g.

the hyperfocal distance for any combination of camera, aperture and focal length.

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. For a truncated beam, the appropriate spot size ratio should be applied (see the relevant calc, e.g. 1.12 for truncation at the 1/e² diameter).

Example: Calculate the depth of field of an optical microscope with 100× oil-immersed (n = 1.52) objective with numerical aperture NA = 1.25. The pixel pitch of the microscope camera is … Where λ is the imaging wavelength of light, NACon is the condenser numerical aperture, and NAObj equals the objective numerical aperture. The factor 1.22 has been taken from the calculation for the case illustrated in Figure 4 for the close approach of two Airy disks … Practical Gyan ab hindi mai! Numerical aperture is abbreviated as NA and shows the efficiency with which light is collected inside the fiber in order to get propagated.. We know light through an optical fiber is propagated through total internal reflection.Or we can say multiple TIR takes place inside the optical fiber for the light ray to get transmitted from an end to another through an optical fiber. Numerical Aperture (N.A.): This is a number that expresses the ability of a lens to resolve fine detail in an object being observed.

f/# and Numerical Aperture. 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. Numerical Aperture of Optical Fiber Sytems Problems with Solutions A numerical aperture of optical fibers calculator is included in this site and may be used to check the calculations in the following problems. Problem 1 let n = 1, n 1 = 1.46 and n 2 = 1.45 in the diagram of the optical fiber system above. The calculator determines the depth of field of a microscope with a digital camera. Example: Calculate the depth of field of an optical microscope with 100× oil-immersed (n = 1.52) objective with numerical aperture NA = 1.25.

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/# ). 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.

5). What is the formula for the numerical aperture? The main formula for numerical aperture (NA) is = √( Ƞ12- Ƞ22) 6). How to select an optical fiber? There are various parameters that should be taken into reflection to select the suitable optical fiber in signal propagation. 7).What is the working principle of a fiber optic cable? Numerical Aperture of Optical Fiber Sytems Problems with Solutions A numerical aperture of optical fibers calculator is included in this site and may be used to check the calculations in the following problems.
