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.

Power and intensity Numerical Aperture of A Plastic Optical Fiber Trilochan Patra Assistant professor, Department of Electronics and Communication Engineering Techno India College of Technology, Rajarhat, Newtown, Kolkata-156, West Bengal, India Abstract: - To use plastic optical fibers it is useful to know their numerical apertures. These fibers have a large core A higher numerical aperture objective will be able to capture more of this wavelet than a lower numerical aperture. We discuss numerical aperture further in the next section. So, if the wavelet contains the imaging information that is being shone through the specimen you can now start to see what is meant by resolution. 2006-04-21 · the numerical aperture of a lens is defined as . NA = n sin theta .

Numerical Aperture (also termed Object-Side Aperture) is a value (often symbolized by the abbreviation NA) originally defined by Abbe for microscope objectives and condensers. It is given by the simple expression: µ Numerical Aperture (NA) = n × sin (µ) or n × sin

= equation First, calculate the etendue of the light source given that: The fiber has a core diameter of 50 μm and emits light with a NA = 0.2 where the area of the fiber core is We also discuss computational efficiencies that can be achieved when calculating SOCS kernels, for example by iteratively refining kernels calculated from a As the numerical aperture (NA) increases, the depth of focus becomes The real field of view can be calculated with the following formula: (1) The range of the Stops and Pupils. • NA. • Effective FL, F/# and depth of field. • Vignetting.

Numerical aperture is defined by the formula N.A. = i sin q. where I is the index of refraction of the medium in which the lens is working, and q is one half of the
