A new contact lens is being developed by Dr. Eric Tremblay (a designer) from the Swiss Federal Institute of Technology that may help people see that suffer from age-related macular degeneration. The contact lens features an inbuilt telescope. Read more here
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
This is a fun summary of 10 great new ideas in the medical device industry that could really change your life. As we look back on 2014 and forward to 2015 we should keep these technologies in mind. All of them use photonics at their core.
Great re-cap on the 2014 RRPC Annual Meeting- which was a huge success, as always. The push for the national manufacturing institute in Optics and Photonics to be created here in Rochester, NY is stronger than ever and hopefully our dreams will become a reality with lots of continued hard-work to make it happen.

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.
