Numerical Aperture Definition A numerical aperture is defined as a unitless and dimensionless number that describes the range of angles that a lens can emit or accepts lights. Can numerical aperture be negative? A numerical aperture can not be negative in the sense that an aperture cannot accept or emit a negative amount of light.

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 (NA) The numerical aperture is a measure of the acceptance angle of the fiber.

In the tutorial, the Numerical Aperture slider is utilized to control how image structure evolves as the objective numerical aperture is increased. At the lowest numerical aperture value (0.20), image details visible in the microscope viewport are poorly defined and surrounded by diffraction fringes that are diffuse, but not resolved.

It is defined based on geometrical considerations and is thus a theoretical parameter which is calculated from the optical design. 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. 數值孔徑(英語: NA, Numerical aperture )是光學系統的一個無因次數,用以衡量該系統能夠收集的光的角度範圍。在光學的不同領域,數值孔徑的精確定義略有不同。 At the lowest numerical aperture value (0.20), image details visible in the microscope viewport are poorly defined and surrounded by diffraction fringes that are diffuse, but not resolved. As the slider is moved to higher numerical aperture values (0.50-0.80), the structural outline of the image becomes sharper and higher-order diffraction rings begin to emerge. Numerical aperture (abbreviated as ‘NA’) is an important consideration when trying to distinguish detail in a specimen viewed down the microscope. NA is a number without units and is related to the angles of light which are collected by a lens. In calculating NA (see below), the refractive index of a medium is also taken into account and by matching the refractive index of a slide or cell Definition: Numerical Aperture is the measure of the ability of an optical fiber to collect or confine the incident light ray inside it.

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.
