Metal stents have been available since 1988. Through the 1990’s, stents went through numerous iterations, incorporating different metals and coatings. As the medical products industry moved through the 2000’s, the use of bioresorbable stents became the newest innovation. And, it is a tremendous innovation.
The OptiGauge II is an ideal non-contact thickness measurement system for companies looking to move away from traditional contact measurement systems. It is non-destructive and objective, leaving no margin for operator error. It offers customers extraordinary flexibility in a measurement system. This user-friendly system delivers reliability and sub-micron accuracy so vital to today’s most advanced industries. OptiGauge II can be particularly useful in in Quality, R&D labs, and production floors because it can improve yields, reduce costs, increase quality, and meet compliance requirements.

Human flesh is opaque. As any good dictionary will tell you, that means it has the quality of "not transmitting light; being impenetrable to sight." Well, forget that: scientists now can use light to see inside objects that were traditionally off-limits to the human eye—including our bodies.
There are many types of thickness measurement- one of those being ultrasonic thickness measurement. Ultrasonic thickness measurement has many benefits, but falls short in a few critical areas where optical thickness measurement excels. Here are the details:
One of the most prevalent measurement devices in a medical balloon or catheter manufacturing facility is the micrometer gauge. It is simple and inexpensive. But, this measurement technique is subject to a high degree of operator variability. Another limitation is that it measures total thickness only, and not the actual individual wall thickness. Furthermore, a micrometer compresses the measured part, and must, by design, come into contact with the material. The micrometer does not provide engineers with the precise and detailed information they need to develop and improve production processes. What other issues are there? Read More
Lumetrics was featured in a Glass International publication about how glass thickness measurement is a critical parameter in a successful operation. Vice President Steve Heveron-Smith described how an all fiber-based interferometer, like Lumetrics' OptiGauge™ can work in different glass applications.
Common methods for measuring glass include laser triangulation, spectrometers, digital micrometers, and manual touch gauges of various types. Manual touch gauges have all the issues inherent to manual measurements including variability based on user, longer time to measure, data integrity, and operator error. Automated gauges like spectrometers, and laser triangulation gauges remove the data integrity and time to measure issues, but often result in issues with set-up and usability.
Lumetrics® has developed an all-fiber based interferometer called the OptiGauge™. Traditional white light interferometers use a mechanical rotating flywheel with mirrors to provide the core function of creating interference fringes- what the system measures. The rotating flywheel is used in conjunction with free space optics, which channel a light beam through a series of mirrors and prisms and then out through an optical fiber to the probe and measured surface. These mirrors can be subject to alignment and use issues over time.
