Accurate Bow Measurements In Glass Capillary Tube

High quality glass tubing production requires tightly controlled manufacturing processes. OptiGauge® II, Lumetrics' low coherence interferometer, can aid the control of the straightness of the tube by measuring its bow when Reference Signal Generator (RSG) is added.

When paired with custom software and a precision rotation adjustment stage, OptiGauge II can characterize a tube during both the incoming material inspection and outgoing product quality control in the following:

  • Wall thickness
  • Inner  diameter (ID)
  • Outer diameter (OD)
  • Bow
  • Concentricity
  • Ovality
This app note details the flexibility and robustness of the OptiGauge II for this application.
