RayCi supports several 2D techniques to determine the beam width of a laser beam. The customer can choose the best technique for their application. This extensive tool on beam width techniques is unique on the market for laser beam profiling.
2nd Moments (D4s)
Based on the ISO international standard definition for beam width. It describes the variance of the intensity distribution related to the Center of Gravity.
Gauss / Super Gauss
Based on a mathematical model to find the best fitting function for the two-dimensional intensity distribution of the beam.
Plateau / Geometry / Area
Based on a geometrical model to find the best fitting shape of the beam.
Knife Edge / Moving Slit
Based on classical measurements with knife-edge or moving slit.
