DWC® is a one shot device offering detailed beam propagation analysis in a range up to several Rayleigh distances in the beam propagation direction.

Without displacing the device, the beam's energy - related characteristics such as beam celtroid and peak locations, and peak fluences can be precisely and quickly computed by purely numerical procedures, in a desired number of planes around the position of DWC®.

The quality of the laser beam and the visualization of its hot spots can be monitored with no operator intervention over large distances around the laser beam waist.
