Stigmatische und einfach astigmatische Strahlen. Radiant Zemax Knowledge Base. For astigmatic beams, however, a more rigorous definition of the beam width has to be used:. The profile is then measured from the knife-edge velocity and its relation to the detector’s energy reading.

Test methods for laser beam widths, divergence angles and beam propagation ratios General astigmatic beams. The baseline is easily measured by recording the average value for each pixel when the sensor is not illuminated. The solution for D86 is found by computing the area of increasingly larger circles around the centroid until the area contains 0.

Five definitions of the beam width are in common use: Faisceaux stigmatiques et astigmatiques simples Title in German Laser und Laseranlagen.

Retrieved June 3, Take the smart route to manage medical device compliance. Find Similar Items This product falls into the following categories. Stigmatic and simple astigmatic beams. This is the beam diameter definition that is used for computing the maximum permissible exposure to a laser beam.

Stigmatic and simple astigmatic beams Status: Pruefverfahren fuer Laserstrahlabmessungen, Divergenzwinkel und Beugungsmasszahlen. The simplest way to define the width of a beam is to choose two diametrically opposite points at which the irradiance is a specified fraction of the beam’s peak irradiance, and take the distance between 11146-1 as a measure of the beam’s width. The measured curve is the integral of the marginal distribution, and starts at the total beam power and decreases monotonically to zero power.

The term “beam width” may be preferred in applications where the beam does not have circular symmetry.

Before the advent of the CCD beam profiler, the beam width was estimated using the knife-edge technique: 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.
