Multi-layer thickness and surface measurement solution provides a new alternative for non-contact measurement of single and multi-layer plastics, glass, and numerous coatings
Lumetrics has developed a new generation of interferometers; a dual interferometer with piezo electric fibre stretchers instead of free space optics, and with an integrated laser to provide extremely accurate measurements, in online production environments.
This product provides the speed, accuracy, durability and ease of use that makes it ideal for production lines as well as labs.
With few moving parts and no nuclear material, the Lumetrics DI 330 multi-layer thickness and surface measurement solution provides a new alternative for non-contact measurement of single and multi-layer plastics, glass, and numerous coatings.
The dual interferometer (DI) engine uses a light emitting diode (LED) to create reflections off surfaces and combines an internal laser to perform rapid and accurate measurements of these reflections and convert them to thicknesses.
The DI 330 delivers accuracy of 200nm and resolution of 30nm at speeds of 100 samples per second in real time.
The DI 330 can measure thicknesses of between 12microns and 5mm, and can measure thinner samples through the use of subtractive calculations.
Designs are in place that decrease the thicknesses Lumetrics can measure as well as increase the speed.
The DI 330 is extremely flexible in its functionality and markets.
It measures thicknesses of multilayer plastics in a single online view, measures adhesives, coatings, and laminates.
It can be used for off-line as well as on-line quality assurance in a multitude of applications in the flexible packaging, glass, optics, and electronics industries.
On-line tests were conducted with Black Clawson measuring multi-layer plastics at speeds of 300-600 feet per minute; faster speeds can also be measured.
Lumetrics' technology provides 100% on-line inspection to eliminate product failures in the field, improve the profile, increase productivity and decrease costs through reduced scrap and returns, and provide increased product quality and customer satisfaction.
The DI 330 allows process improvements through continuous monitoring, statistical analysis, and system modifications.
The DI 330 software architecture includes industry standard software modules for critical functions such as interpretation of data, statistical analysis, and the user interface.
The engineering team at Lumetrics says it will design and assemble a system that solves a customer's problems in a flexible and cost effective manner.
