- The product under validation was OptoFidelity's WG-GAT, a Littrow Diffractometer for measuring AR waveguide grating manufacturing quality.
- WG-GAT’s measurement accuracy was validated based on measurements performed by VTT MIKES, one of the leading metrology institutes for accurate grating period measurements worldwide.
- Fully automated WG-GAT measures diffraction grating pitch and orientation and can find grating defects on picometer and arcsecond scale accuracy, making it the preferred choice for AR waveguide testing.
Tampere, Finland - June 27, 2023 - OptoFidelity, a leading provider of advanced AR/VR measurement solutions, is proud to announce the validated measurement accuracy of OptoFidelity's waveguide grating analysis test system, WG-GAT. This achievement was made possible by OptoFidelity's extensive, demand-driven product development and cooperation with VTT MIKES, the National Metrology Institute of Finland.
