Glass Slimming and Polishing processes frequently demand stringent thickness tolerances. Bristol’s non-contact optical thickness gauges quickly measure these substrates with sub-micron accuracy and can be easily integrated into production workflows. A single instrument can support multiple test stations to provide rapid thickness measurements across large sheets and wafers.
- Non-contact technique will not scratch or deform the thinnest glass
- Easily integrates into your manufacturing and quality control processes
- Measures substrates as thin as 12 µm with high accuracy (± 0.1 µm) and excellent repeatability (0.02 µm)
- Up to 8 test stations in a single instrument supports multiple measurements over a large area

Production line example of a thickness measurement system utilizing 3 test stations.
