Objective-C is a high-level general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. Originally developed by Brad Cox and Tom Love in the early 1980s, it was selected by NeXT for its NeXTSTEP operating system.
In optics, the numerical aperture (NA) of an optical system is a dimensionless number that characterizes the range of angles over which the system can accept or emit light. By incorporating index of refraction in its definition, NA has the property that it is constant for a beam as it goes from one material to another, provided there is no ...
The numerical aperture (NA) of an optical system (e.g. an imaging system) is a measure for its angular acceptance for incoming light. It is defined based on geometrical considerations and is thus a theoretical parameter which is calculated from the optical design.
Mar 5, 2024 · Objective-C is a general-purpose, object-oriented programming language that was developed in the early 1980s by Brad Cox and Tom Love. Mainly, it is used for software development on Apple’s macOS, iOS (mobile), watchOS, and TVOS platforms.
Sep 20, 2018 · Where R is resolution (the smallest resolvable distance between two objects), NA equals numerical aperture, equals wavelength, NA (obj) equals the objective numerical aperture, and NA (Cond) is the condenser numerical aperture.
