Your basket is empty. Intrinsic and geometrical laser beam classification, propagation and details of test methods”. The fraction of total beam power encompassed by the beam width depends on which definition is used.
Reconstruction is possible for beams in deep UV to far IR.
You may find similar items within these categories by selecting from the choices below:. To overcome this drawback, an innovative technology offered commercially allows multiple directions beam scanning to create an image like beam representation. 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. 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.
BS EN ISO 11146-1:2005
The width of laser beams can be measured by capturing an image on a cameraor by using a laser beam profiler. Please download Chrome or Firefox or view our browser tips. The definition given before holds for stigmatic circular symmetric beams only.
Worldwide Standards We can source any standard from anywhere in the world. January Number of pages: Legal notices Photo credits FAQ.
By mechanically moving the knife edge across the beam, the amount of energy impinging the detector area is determined by the obstruction. Retrieved June 3, Get a quote for certification of systems, products or services, and get certified. Test methods for laser beam widths, divergence angles and beam propagation ratios.

Fite Date of publication: A beam may, for example, have an elliptical cross section, in which case the orientation of the beam diameter must be specified, for example with respect to the major or minor axis of the elliptical cross section.
Beam diameter – Wikipedia
Isk the advent of the CCD beam profiler, the beam width was estimated using the knife-edge technique: Ixo website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3.
