f/{{a We analytically calculate the focus setting for a beam with a high numerical aperture. (NA) that optimizes its Strehl ratio in the case of small aberrations up to the Numerical Aperture is defined as the Sine of half of the angle of fibre's light acceptance cone. i.e. NA= Sin θa where θa, is called acceptance cone angle.

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 pixel pitch of the microscope camera is … Encyclopedia > letter N > numerical aperture.

This is not true.

Web Calculator Illumination Calculate the illumination … Continue reading → 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. The effective numerical aperture of the application can only be calculated if the user knows the beam diameter.

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. The numerical aperture is dependent upon the angle of the inverted cone of illumination entering the objective aperture, as well as the refractive index of the imaging medium: 2 $$NA_{ (Obj) } = n(sinθ)$$ Numerical Aperture Calculator.

Formula symbol: NA. Units: (dimensionless) How to cite the article; suggest additional 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.
