VR/AR headsets are rapidly progressing from a gaming novelty to an integrated entertainment platform and acceptance in industry as an interface for inventory control, design, and manufacturing processes. Whether the VR/AR systems utilize Fresnel technology, waveguides or more traditional displays, thickness characterization is critical during their manufacture and quality assurance steps. Bristol Instruments non-contact optical thickness gauges offer high accuracy thickness measurement with excellent repeatability to meet your most stringent manufacturing specifications.
- Simultaneous measurement of multiple component layers, including Liquid Optically Clear Adhesives
- Non-contact optical technique means no damage or deformation during the measurement process
- Real-time results for fast testing throughput, with high accuracy (± 0.1 µm) and excellent repeatability (± 0.02 µm)
- Included Opti-Cal ™ software offers a QC Mode which provides easy to understand PASS/FAIL measurements based on your design criteria
