Non-Contact, Light-Based Measurement of Medical Balloons & Catheters

One of the most commonly used measurement devices in a medical balloon or catheter manufacturing facility is the micrometer gauge. These gauges are cost-effective but have limited measurement capabilities. White light interferometry technology eliminates the subjective nature of micrometers.

Our article reviews thickness data obtained in a series of interferometric measurements and discusses an easy method for fast and accurate wall measurements.
