Non-contact thickness measurement
The Optical Thickness Gauge products from Bristol Instruments use the unique properties of light to measure the thickness of transparent and semi-transparent materials. These systems direct light through an optical probe to the part under test. Reflections from every surface and material interface are collected and returned to the Optical Thickness Gauge for analysis.
- No damage or deformation to hard and soft materials.
- Simultaneous thickness measurement of multiple layers,
including air gaps.
Reliable accuracy and exceptional repeatability
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.
Ideal for production and quality
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.
- Straightforward operation enables rapid measurement
of multiple parts.
- Measurement reproducibility eliminates variability
between different technicians.
