How Terahertz Metrology Works?

TeTechS' terahertz metrology solutions are powered by terahertz waves, a form of light with its wavelength falling along the electromagnetic spectrum between microwave and infrared. For various industrial applications, e.g. non-contact thickness measurement, terahertz metrology has distinctive advantages over optical, ultrasonic, and x-ray metrologies.

Terahertz time-of-flight measurement technique is ideal for multi-layer thickness measurement in plastic containers. The layer thickness is calculated based on the speed of light in the material, hence it is a "true thickness" measurement with no on-going calibration required. Terahertz waves pass through opaque and transparent plastics, and accurately measure multiple layers with better than 1 microns (0.04 mil) accuracy.

As a fully automated and hands-off turn-key solution combined with a gauge R&R less than 4%, TeTechS' PlastiMeasure offers a new way for plastic container manufacturers to control their production process and protect their customers' brand by supplying them with highest quality products.
