Optical Thickness Gauges

Bristol Instruments offers a family of instruments that use the unique properties of light to precisely measure the critical parameter of thickness. The primary advantage of this optical technique is that it makes non-contact measurements with sub-micron accuracy. Both hard and soft materials are analyzed without damage or deformation. In addition, this optical technique enables the simultaneous measurement of up to 31 layers. Originally designed for R&D and laboratory environments, Bristol Optical Thickness Gauges have evolved into high volume production and in-line quality control tools. These instruments surpass the capabilities of traditional measurement techniques and address today’s challenging manufacturing tolerances. Rugged design, straightforward operation, and production-ready software features allow for easy integration and use in laboratory and manufacturing environments.More products
