Exceptional measurement repeatability ensures greater consistency in the production of plastic films, medical membranes, glass tubing, and ophthalmic products.

Bristol Instruments, Inc., a leader in optical interferometer-based instrumentation, has set a new standard of performance for its 157 Series Optical Thickness Gauge. The 157 system continues to measure absolute thickness to an accuracy of ± 0.1 μm. But now, its measurement repeatability is ± 0.02 μm, an improvement of 2½ times over the previous specification.

Thickness information is critical in the development and production of materials such as plastic films, medical membranes, glass tubing, and ophthalmic products. Accurate and precise measurement techniques are necessary for product evaluation and process improvement. The 157 Optical Thickness Gauge is the only thickness gauge that provides both reliable accuracy and exceptional repeatability. An accuracy of ± 0.1 μm makes sure that the desired material thickness has been achieved. This accuracy is guaranteed because the 157 system’s measurements are continuously referenced to a built-in standard of length that is recognized by NIST. Repeatability of ± 0.02 μm makes the 157 system a very powerful tool for understanding and controlling the manufacturing process. The result is reduced variability in material thickness.

“Bristol Instruments engineers are experts in optical interferometer technology,” said Dr. Brian Samoriski, President of Bristol Instruments. “This ensures that products such as the 157 Optical Thickness Gauge will provide the performance that is required for the most demanding applications.”
