Optical beam clipping

WebWhen a lens with too low NA is used, the resulting collimated beam can be distorted (aberrated) or even truncated. There is a weak dependence of numerical aperture on the … In laser science, laser beam quality defines aspects of the beam illumination pattern and the merits of a particular laser beam's propagation and transformation properties (space-bandwidth criterion). By observing and recording the beam pattern, for example, one can infer the spatial mode properties of the beam and whether or not the beam is being clipped by an obs…
