Non-contact thickness gauge range extended
Bristol Instruments has added two models to its line of non-contact optical thickness gauges. The 157XLS (Extra Long Scan) and 137XLS systems are the latest additions, both of which extend the maximum measurement limit to 80mm.
These models maintain industry leading accuracy as high as ± 0.1 μm for the 157XLS models and long-term repeatability of up to ± 0.02 μm.
For less exacting requirements, the 137XLS measures accuracy as high as ± 1.0 μm and features a long-term repeatability of ± 0.05 μm.
These instruments use the properties of light to measure material thickness without damage or deformation. Up to 31 individual layers, as well as total thickness, can all be measured simultaneously.
This longer scan measurement capability was added primarily to accommodate thicker, multi-element optical components and assemblies, as well as large diameter medical devices.
