- The 137 Optical Thickness Gauge is a slightly modified version of the industry-leading model 157. It has all the functionality, but is intended for less exacting applications, measuring absolute thickness to an accuracy of ± 1 μm and with a repeatability of ± 0.05 μm.
- Non-cantact thickness measurements
- All layers are measured simultaneously
- Absolute thickness measured to an accuracy of ± 0.1 μm
- Exceptional long-term measurement repeatability of ± 0.05 μm
- Continuous calibration ensures confidence in thickness measurements
- Unique interferometer technology for the most reliable operation
- Straightforward operation and versatile integration
- Rugged design for manufacturing environments
