Bristol Instruments expand its family of non-contact thickness gauges with addition of the model 137LS Optical Thickness Gauge

VICTOR, NEW YORK October 3, 2018Bristol Instruments, Inc., a leader in optical interferometer-based instrumentation, has expanded its family of non-contact thickness gauges with the addition of the model 137LS Optical Thickness Gauge. This latest system has the capability to measure the thickness of materials up to 28 mm. Expanding the measurement capability of the 137 Optical Thickness Gauge will benefit engineers involved in the development and production of thicker products, such as medical tubing and multi-element optical lens systems.

The measurements provided by the 137LS Optical Thickness Gauge have an accuracy of ± 1 μm and a repeatability of ± 0.05 μm. Because the 137LS system uses light to measure material thickness, it can accommodate both hard and soft materials without damage or deformation. What’s more, all material layers are measured simultaneously. For example, all the critical dimensions of a glass tube including top wall thickness, bottom wall thickness, outer diameter, and inner diameter are all measured at the same time.

“It was evident that there was a need for our precise, non-contact thickness measurement capability for applications involving thicker materials,” said Don Jarvie, Business Development Manager for the Optical Metrology Products Group at Bristol Instruments. “We are confident that the new 137LS system is the best solution for a variety of advanced thickness measurement applications.”
