Multi-layer Measurement with the Lumetrics OptiGauge II

Posted March 16, 2020 by Kristin

The OptiGauge II is a user-friendly non-contact thickness measurement system for multi-layer materials that delivers reliability and sub-micron accuracy so vital to today’s most advanced industries. The OptiGauge II can be particularly useful in Quality, R&D labs, and production floors because it can improve yields, reduce costs, increase quality, and meet compliance requirements.

Transparent armor

Posted June 26, 2019 by Kristin

Abstract: A method of identifying the material and determining the physical thickness of each layer in a multilayer structure is disclosed.The method includes measuring the optical thickness of each of the layers of the multilayer object as a function of wavelength of a light source and calculating a normalized group index of refraction dispersion curve for each layer in the multilayer structure.  The measured normalized group index of refraction dispersion curves for each of the layers is then compared to a reference data base of known materials and the material of each layer is identified.  The physical thickness of each layer is then determined from the group index of refraction dispersion curve for the material in each layer and the measured optical thickness data.  A method for determining the group index of refraction dispersion curve of a known material is also disclosed.

OptiGauge 2000

Posted February 15, 2019 by Kristin

 Lumetrics is pleased to introduce a brand new product to our OptiGauge portfolio: the OptiGauge 2000.  This non-contact thickness measurement system is based on the time-domain low-coherence interferometry. This technology enables absolute thickness measurement of any material, which is transparent or partially transparent to the measurement light. The OG-2000 uses infrared light with the center wavelength of approximately 2 microns. The OG-2000 is designed to measure specialty and rare materials, such as Germanium, Gallium Arsenide, Beryllium, nano-composite optical ceramics and others. Conventional glass and plastic materials can be measured as well. Our patented technology allows for fast real-time measurements, and can be used for on-line process control as well as off-line quality control purposes.

Refractive Index Measurement System for Contact Lens in a Natural Hydrated State

Posted February 01, 2019 by Kristin

A collaboration between Lumetrics and Johnson & Johnson

Accurate refractive index of the contact lenses is one of the most important parameters needed to properly evaluate the lens performance. Measurements of the refractive power and other optical properties of the lenses are typically conducted in solution, and converted to in-air performance. Such an approach is very sensitive to errors in the refractive indices of both the lens and the solution.

Optical Thickness Measurement of Multilayer Films

Posted September 10, 2018 by Kristin

Abstract — Manufacturers of multi-layer films can realize significant cost savings, product quality improvements, and reduce the risk of product failures by accurately measuring individual layer thicknesses of multi-layer materials instead of relying on gauging that can only provide total thickness.
