SID4 range and Software


COMPLETE BEAM CHARACTERIZATION | High resolution wavefront analysis software

The SID4 software package manages wavefront acquisition and analysis with one of our wavefront sensors. This software is entirely dedicated to laser beam analysis. It eases the use of the wavefront sensor (camera settings, acquisition modes, alignment helpers, automatic mask adjustment) and provides relevant tools for beam phase analysis: PSF, wavefront aberrations, laser beam parameters, beam profiles…
