Featuring resolution of 250 000 measurement points, high dynamic range (± 1500 λ of wave tilt at 633 nm), and real time wavefront analysis at 25Hz video frame rate, DWC® is an ideal tool for laser beam analysis.

Multiple views of the reconstructed high resolution wavefront, containing 3D plot, wavefront gradient, fringes display are output in real time.

For laser beam measurement, the technique uses Digital Wavefront Sensor® to obtain high-resolution intensity and wavefront images of the propagating beam at one location on a 1M pixel CCD array camera. From the one-shot intensity and phase measurements and numeric propagation the laser beam is obtained at >10 positions. The instrument is suitable for measurement of both CW and pulsed lasers down to single-shot rates, and provides quantitative measurement of numerous beam spatial characteristics in accordance with the ISO 13694 standard and M² parameters according to the ISO 11146 standard. Beam diameters are obtained with accuracy to better than 2% that translates to M² measurements with accuracy to better than 4%.
