Расходимость пучка Расходимость пучка
В электромагнетизме, особенно в оптике, расходимость пучка — это угловая мера увеличения диаметра или радиуса луча по мере удаления от оптической апертуры или апертуры антенны, из которой выходит луч. Термин актуален только в области «дальнего... Википедия
The beam divergence is a measure for how fast a laser beam expands far from its focus.
In optics, laser beam divergence refers to how much a beam spreads over a distance. Imagine a cone where the tip is the theoretical origin of the laser beam ...
11 июл. 2023 г. · For a circular beam, divergence is defined as the angular measure of how the beam diameter increases with the distance from the laser aperture.
The beam divergence can reach 25 degrees along its vertical direction (fast axis), but only around 8 degrees along its horizontal axis (slow axis).
Definition. semi-angle of a cone, passing through the thruster exit, containing a certain percentage of the current of an ion beam at a certain distance of ...
Measuring the beam in the focal plane of the lens yields the beam's 'raw' divergence, simply by dividing the beam diameter in the focal plane by the focal ...
A Gaussian beam is an idealized beam of electromagnetic radiation whose amplitude envelope in the transverse plane is given by a Gaussian function. Beam diameter · Rayleigh length · Transverse mode
