Beam Profiling for Small Beam Widths or Spot Size

Beam width or spot size is an important parameter to identify in selecting the optimal beam profiler. Scanning slit beam profilers are ideal for measuring small Gaussian beams. DataRay Inc.’s Beam’R2 and BeamMap2 are capable of measuring beams as small as 2 µm using knife-edge slits. Camera-based beam profilers, such as the WinCamD and BladeCam series, are ideal if a true two-dimensional image is desired. This is essential when viewing non-Gaussian beams...
