Bristol Instruments Optical Thickness Gauge products measure material thickness to an accuracy as high as ± 0.1 μm with a repeatability of ± 0.02 μm. This performance is guaranteed by comparing every measurement to a built-in intrinsic standard of length. The result is reliable accuracy, year after year, without the need for external calibration or any user intervention.
- High accuracy of ± 0.1 μm confidently supports the most demanding applications.
- Thickness changes as small as 0.04 μm can be detected.
The Optical Thickness Gauge products from Bristol Instruments combine straightforward operation with versatility to allow for easy integration into virtually any manufacturing process. These systems operate with a PC connected directly by USB or through a local area network via Ethernet. Software is provided to facilitate alignment of the optical probe, control measurement parameters, and report measurement data in a variety of formats.
