Full width at half maximum. For example, applications of high-energy laser weapons and lidars require precise knowledge of how much transmitted power actually illuminates the target. Retrieved from ” https: The main drawback of the knife-edge technique is that the measured value is displayed only on the scanning direction, minimizing the amount of relevant beam information. Optics and photonics – Lasers and laser-related equipment – Measurement of phase retardation of optical components for polarized laser radiation ISO To overcome this drawback, an innovative technology offered commercially allows multiple directions beam scanning to create an image like 11146-1 representation.

ISO 11146-1:2005

Pruefverfahren fuer Laserstrahlabmessungen, Divergenzwinkel und Beugungsmasszahlen. The angle between the maximum peak of radiated power and the first null no power radiated in this direction is called the Rayleigh beamwidth. The beam diameter or beam width of an electromagnetic beam is the diameter along any specified line that is perpendicular to the beam axis and intersects it.


Five definitions of the beam width are in common use: Lasers and laser-related equipment. Reconstruction is possible for beams in deep UV to far IR. Intrinsic and geometrical laser beam classification, propagation and details of test methods”.

Faisceaux stigmatiques et astigmatiques simples.

The main advantage of this scanning method is that it is free from uso size limitations as in CCD cameras and allows beam reconstructions with wavelengths not usable with existing CCD technology. Caution the offer 1 user is reserved for a single user, any broadcast even within his company is prohibited. The D86 width is often used in applications that are concerned with knowing exactly how much power is in a given area.
