What does numerical-aperture mean? the squares of the refractive indexes of the core (n 1 ) and the cladding (n 2 ), and as expressed in the equation: NA = (n  

Numerical Aperture (N.A.): This is a number that expresses the ability of a lens to resolve fine detail in an object being observed. It is derived by a mathematical formula (n sine u) and is related to the angular aperture of the lens and the index of refraction of the medium found between the lens and the specimen.

The dependence of the measured value on the numerical aperture in the form of an analytical formula is obtained. It is established that the measured value is  1. Specifications. To achieve the highest quality, the optical formula for this very high (0.35) numerical aperture optics had to provide a modulation transfer function  Etendue and its relationship to F/# and NA of an optical system will be discussed, in addition to Examples of Throughput (Radiant Flux) Calculation. Relative aperture, the measure of the light-gathering power of an optical system.

Where r is resolution (the smallest resolvable distance between two objects), NA is a general term for the microscope numerical aperture, λ is the imaging wavelength, NA (obj) equals the objective numerical aperture, and NA (cond) is the condenser numerical aperture.

It is given by the simple expression: µ Numerical Aperture (NA) = n × sin (µ) or n × sin Where R is resolution (the smallest resolvable distance between two objects), NA equals numerical aperture, λ equals wavelength, NA (obj) equals the objective numerical aperture, and NA (Cond) is the condenser numerical aperture. The “Numerical Aperture” (NA) is the most important number associated with the light gathering ability of an objective or condenser.

Numerical Aperture The figure above depicts a section of a clad cylindrical fiber showing the core with refractive index of N1 and the clad with index of N2. Also shown is a light ray entering the end of the fiber at angle (A), reflecting from the interface down the fiber. Numerical aperture is commonly used in microscopy to describe the acceptance cone of an objective (and hence its light-gathering ability and resolution), and in fiber optics, in which it describes the range of angles within which light that is incident on the fiber will be transmitted along it. Related formulas One of the several equations related to the original Abbe formula that have been derived to express the relationship between numerical aperture, wavelength, and resolution is: Resolutionx,y or d0 = 1.22λ / [NAObj + NACon] (4) In image space the half-angle the exit pupil makes with the image plane determines Numerical Aperture (NA). The formula is: NA = sin q where NA is Numerical Aperture and q is the half-angle.

Immersion oils have a considerably higher refractive index, sometimes even up to 1.56. Numerical Aperture. The figure above depicts a section of a clad cylindrical fiber showing the core with refractive index of N1 and the clad with index of N2. Also shown is a light ray entering the end of the fiber at angle (A), reflecting from the interface down the fiber. Numerical Aperture is a dimensionless value describing the Light Gathering Power and Resolution capability of a microscope objective lens. NA was described by Ernst Abbe in 1873 and is defined: where: n = the lowest refractive index between the condenser and objective; a = the angular aperture, or collection angle, Acceptance angle or Numerical aperture.

The numerical aperture formula defines it as: The f-number of a microscope is the working distance of the objective divided by the aperture diameter. It is defined by the equation: Spectroscopy Formulas Einstein-Planck equation shows that light energy is related to its wavelength. The equation is: Homework Statement An optical system consists of a thin lens in air with f = 100 mm. An aperture stop with a diameter of 20 mm is placed 25 mm to the right of the lens.
