Spherical Aberration Standards and Measurement System Stability Over Time

Posted March 01, 2017 by Kristin

A Shack-Hartmann wave-front sensor system has been used to measure a set of plano-convex lenses at two different times, separated by almost 2 years. The plano-convex lenses were selected to cover a range of powers and apertures relevant to intraocular lenses, and were measured at two different orientations. The results demonstrate the high temporal stability of the measurement system, as well as of the glass standard.

Optical Thickness Measurement of Coronary Balloons and Medical Tubing

Posted February 15, 2017 by Kristin

Medical device manufacturers often struggle when inspecting balloons, tubes, stents, and other medical products with many simplistic measurement devices in use today. There are limitations when using micrometers, microscopes, pin gauges, and razor blades that limit accuracy, repeatability, and general ease-of-use.

Online multilayer film system

Posted February 07, 2017 by Kristin

A customer presented Lumetrics with a 5 layer product constructed of a liner, adhesive, middle layer, adhesive and a liner.  The product is made in two operations.  The first operation coats the liner with adhesive then adds the middle layer.  The second operation adds adhesive to the middle layer and then adds the final  liner.

The ability to control the adhesive layer was a critical parameter.  The customer needed to know the adhesive thickness when applied in a wet state and again when cured in a dry state.

Extended Measurement Range System for the Measurement of Thick Glass

Posted February 01, 2017 by Kristin

A customer approached Lumetrics with a need to measure float glass with a physical thickness of up to 25mm (38mm optical). The standard OptiGauge II is capable of a maximum of approximately 20mm optical thickness. The customer also required a probe with a standoff distance of 150mm while retaining good angular tolerances.
