1.25), a drop of this special oil is placed between the lens and the slide. 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; Airy Discs; The limit of resolution (or resolving power) is a measure of the ability of the objective lens to separate in the image adjacent details that are present in the object.

Airy diffraction pattern sizes and their corresponding radial intensity distribution functions are sensitive to the combination of objective and condenser numerical apertures as well as the wavelength of illuminating light (when monochromatic light is used to illuminate the specimen). How can numerical aperture be increased? There are two ways to increase a numerical aperture. First, the maximum angle of light that the lens can emit or accept can be increased. Second, the index of refraction can be increased by changing the material of the lens. How does numerical aperture affect resolution?

The wavelength of light is defined as the distance between any two successive crests or troughs of the Other The numerical aperture of a microscope objective is the measure of its ability to gather light and to resolve fine specimen detail while working at a fixed object (or specimen) distance. Resolution of an optical microscope is defined as the smallest distance between two points on a specimen that can still be distinguished as two separate entities. Increasing the f/# by a factor of √2 2 will halve the aperture area, decreasing the light throughput of the lens by a factor of 2. Lenses with lower f/#s are considered fast and allow more light to pass through the system, while lenses of higher f/#s are considered slow and feature reduced light throughput. Numerical Aperture and Image Resolution - Java Tutorial The image formed by a perfect, aberration-free objective lens at the intermediate image plane of a microscope is a diffraction pattern produced by spherical waves exiting the rear aperture and converging on the focal point. 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.
