Scanning Based Systems: Knife-edge, Slit, and
Pinhole Profilers
Knife-edge, slit, and pinhole scanners generate a profile by
mechanically moving a knife-edge or an aperture (slit or pinhole)
across the beam in a plane orthogonal to the optical axis. The light…

More on Profiles Pinhole Alignment
The targets on the Home (or Alignment) Screen are used for initial
alignment to get the tracks of the scanning pinholes to cross the
transformed beam. This simultaneously aligns the optical axis of the
ModeMaster…

…pinhole intensity profiles. This feature should be used
when it is impossible to obtain a large enough signal on the
profile screens to accurately observe the profile characteristics
of a beam using the smaller pinhole (10 microns). To accurately
observe the beam profile with a pinhole,…

…, the
pinhole used to scan the beam must be 17% of the diameter of
the beam being scanned. Therefore, the smaller pinhole is
normally used for the Far Field profile that is scanned at the
beam's focal plane. For cases in which the signal from the
smaller pinhole is not sufficient…

Like the moving pinhole, measurement of the power transmitted
past a moving knife edge allows on-the-fly measurement of beam
diameter as the distance traveled between set lower and upper transmitted power levels. Unlike the pinhole, the knife-edge does not
require…
