Bristol Instruments extends scope of its thickness gauges
Two new models have been added to Bristol Instruments’ 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. The longer scan measurement capability was added primarily to accommodate thicker, multi-element optical components and assemblies, as well as large diameter medical devices.
The new models maintain industry leading accuracy as high as ± 0.1 microns for the 157XLS models and long-term repeatability of up to ± 0.02 microns. For less exacting requirements, the 137XLS measures accuracy as high as ± 1.0 microns and features a long-term repeatability of ± 0.05 microns.
Bristol’s thickness gauges use the unique properties of light to measure precise material thickness of transparent and semi-transparent materials without damage or deformation. Up to 31 individual layers as well as total thickness can all be measured simultaneously.
