OptoFidelity WG-GAT
Waveguide Grating Analysis System
High-Accuracy Diffractometer for AR Waveguide Grating Characterization.
High Precision
WG-GAT is a superior alternative to conventional microscopy techniques. It achieves up to 50 times higher accuracy, repeatability, and resolution, which is required to match the strict AR waveguide grating manufacturing tolerances. In addition, WG-GAT’s operator-independent performance and traceable accuracy further enhance its credibility and applicability in consistent, reliable, high-precision measurements of gratings.
Full automation
WG-GAT is an off-the-shelf, easy-to-use, fully automated system developed specifically for AR industry needs. It provides efficient grating inspection and cost-effective maintenance.
Optimized & Reliable for Production
WG-GAT supports optimizing production processes by assessing master grating quality, determining the need for stamp replacements, and verifying the overall quality of the replication processes. Consequently, it contributes to cost-effectiveness and efficiency enhancements within the waveguide development workflow, aligning well with the imperatives of the AR industry’s quality standards and production demands.
Advanced Analysis
WG-GAT can also be combined with WG-IQ, where you can link specific shortcomings in image quality in your waveguide back to the quality issues or defects in its grating structure.
