    8/26/2015

    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
