OptoFidelity WG-GAT is a high-accuracy Diffractometer for AR waveguide grating characterization.
In this Mini-Webinar our Product Owner Haoxue Wang, will explain a new feature of WG-GAT: Diffraction Efficiency.
The Diffraction Efficiency Measurement is a ratio of the power of the incident laser beam (before the diffraction from the grating) vs. the diffracted laser beam (after the diffraction from the grating).
With the DEM you can detect deviations of efficiency across a grating.
Learn how WG-GAT measures the Diffraction Efficiency by watching our Mini-Webinar.
