VICTOR, NEW YORK January 19, 2021 – 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 80 mm. 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 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 unique 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.
“Based on input from our customers, this extended measurement range will enable the precision testing needed for more complex optical assemblies and medical devices,” said Don Jarvie, Business Development Manager for Metrology Products at Bristol Instruments. “This new capability is provided without sacrificing our industry-leading measurement accuracy and repeatability.”
About Bristol Instruments
Since its founding in 2005, Bristol Instruments has solely focused on designing, manufacturing, and marketing precision instruments using its expertise in optical interferometry. Bristol’s flagship products accurately characterize the wavelength and spectral properties of lasers and are used by scientists and engineers at universities and government and industrial laboratories. They are also used for the development and production testing of laser transmitters used in optical fiber communications. In addition, Bristol Instruments provides interferometer-based products to reliably measure critical physical dimensions of materials such as specialty plastic films, medical tubing, and ophthalmic products.
