Bristol Instruments has added two new 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.
Bristol Instruments adds new extra-long scan models to its line of non-contact thickness gauges
These new models still maintain industry leading accuracy as high as ± 0.1 μm for the 157XLS models and long-term repeatability of up to ± 0.02. For less exacting requirements, the 137XLS measures accuracy of ± 0.05 μm.
This longer scan measurement capability was added primarily to accommodate thicker, multi-element optical components and assemblies, as well as large diameter medical devices.
Don Jarvie, Business Development Manager for Metrology Products at Bristol Instruments, said: "Based on input from our customers, this extended measurement range will enable the precision testing needed for more complex optical assemblies and medical devices. This new capability is provided without sacrificing our industry- leading measurement accuracy and repeatability.”
