Webaperture, in optics, the maximum diameter of a light beam that can pass through an optical system. The size of an aperture is limited by the size of the mount holding the optical component, or the size of the diaphragm placed in the bundle of light rays.

Webthe aperture information instead, when that is important for your work. We hope this article helps to demystify aperture and vignetting in CODE V. Author Bios Julie Bentley, PhD Julie Bentley received her BS, MS, and PhD degree in optics from the Institute of Optics, University of Rochester. Her PhD thesis ® WebNumerical Aperture In microscopy and the world of fiber optics, “numerical aperture”, rather than F/#, is used to describe light gathering capability. In a medium of refractive index n, the numerical aperture is given by: The larger the N.A., the more flux is collected. In air, the maximum N.A. is 1.
