Push for National Manufacturing Institute in Optics and Photonics is focus of RRPC Annual Meeting

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.

Glass Thickness Measurement Using White Light Interferometry: Lumetrics® Vice President Steve Heveron-Smith Explains Why Glass Thickness Measurement is Crucial to a Successful Operation

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.

Tested Samples: Critical Adhesive Thickness Measurement

adhesive thickness measurement

Sometimes the simplest things cause the biggest problems, especially when it comes to adhesive thickness measurement.  Whether it’s tablet computers, cell phones, medical devices, or other products, the thickness of an adhesive layer can be critical.  Read more.

Thickness Measurement Files: 7 Things We Can Measure

Lumetrics applies their technology to a wide variety of thickness measurement applications.  Here are 7 things we can measure:

1) Absorbable Stents – Read a great article on how a New Standard Focuses on Testing of Absorbable Stents

2. Food Packaging Thickness Measurement Applications– We can make sure your food packaging is of the highest quality, meets all safety standards, and prevents waste during manufacturing.  It’s also very crucial to make sure you don’t have to issue a recall due to safety issues.  Here’s an example of why food packaging is so important. Read more here on how Lumetrics’ can solve your food packaging safety challenges

3) Medical Thickness Measurement Applications– When it comes to medical balloon measurement, Lumetrics® has the capabilities to replace archaic methods of inspection like the micrometer and razor blade. Our measurement systems are a seamless replacement to provide highly accurate, consistent, non-contact, and non-destructive measurements for a variety of medical device products.  Read more about  medical device thickness measurement applications.

4) Glass Thickness Measurement Applications– From our file of “Thickness Measurement” challenges comes Cell phone glass and its structure. It’s very easy for the OptiGauge to measure multiple layers of a product, but how does an engineer know what is good or bad? Protective film, adhesive, outer glass- no problem. We’re often asked to measure the structure, especially the inner layers, which is one of our many areas of expertise. We provide the gold standard of thickness measurement- generating results with an accuracy of .000004″.  Read our white paper on cell phone glass measurement!

Multilayer film thickness measurement

5) Film Thickness Measurement Applications–  Multilayer film thickness measurement provides a challenge to the manufacturers who produce complex films or other light-permeable materials, and the quality personnel who need to inspect them. Antiquated measurement methods are time consuming and often inaccurate. The results may depend more on the accuracy of a weight scale or the sharpness of a razor blade than a true measurement of the product. New, stricter FDA regulations require many products/materials to have NIST traceable inspection history, as well as information that cannot be obtained using obsolete inspection methods. Lumetrics® is the film thickness measurement authority. The OptiGauge™ uses innovative light technology to provide non-destructive, accurate, real-time, film thickness measurement for all types of multilayer films and thin film coatings whether co-extruded, coated, or laminated.  Read more about multi layer film thickness measurement.

tubing thickness measurement applications

6) Tubing Thickness Measurement Applications– In order to meet stringent manufacturing requirements, medical tubing manufacturers strive to maintain consistent and precise wall thickness, inside diameter (ID), outside diameter (OD), concentricity, and the reduction of ovality. Accurate thickness measurement of these components is critical to product quality and the safe practice of patient care.

Utilizing innovative optical measurement technology, Lumetrics’ OptiGauge™ is a non-contact medical tubing and catheter thickness measurement system in use throughout the medical industry for dimensional testing of all types of extruded tubing products. Lumetrics has also developed another new measurement fixture- the LumetriScan™ 360. The LumetriScan™ 360 provides a system for advanced catheter measurement that provides consistent, NIST traceable, and real-time measurement in the production process.  More Information

ophthalmic thickness measurement applications

Opthalmic product thickness measurement solutions.

7) Ophthalmic Thickness Measurement Applications– Today’s ophthalmic products require precise dimensional control to provide the fit and comfort that doctors require and customers demand. Lumetrics’ OptiGauge™ can be integrated into the production line or the quality assessment process, providing real-time measurement of ophthalmic products. The OptiGauge™ provides peace of mind to production and QA by providing inspection on up to 100 percent of all products.  Read More about Lumetrics’ ophthalmic metrology solutions
