Optical Thickness Gauge: 157/137 Series

The 137/157 Series Optical Thickness Gauge from Bristol Instruments is a non-contact instrument designed to accurately and reliably measure the absolute thickness of a variety of transparent, translucent, and some visually opaque materials. The thickness gauge utilizes proven interferometer-based wavelength meter technology to provide the most reliable measurement results.

  • Thickness is measured to an accuracy of ± 0.1 μm
  • Exceptional long-term measurement repeatability of ± 0.02 μm
  • Measurement traceability to NIST standards
  • Broad measurement range of 25 μm to 8 mm
  • Simultaneous measurement of multiple layers
  • Non-contact measurement results in non-destructive testing
  • Rugged design for laboratory and manufacturing environments
  • Integrated 8 channel optical switch ideal for production environment
