PMD modulo

Automated in-line quality inspection, intelligently combined



With PMD Modulo SCHNEIDER introduces quality inspection to the fully automated production environment. For the first time blocked lenses can be measured automatically in-line without interrupting production.

Utilizing UV light for deflectometrical measurement, PMD Modulo is unaffected by common issues with transmissive measurements. It measures diopters and cosmetics directly and non-destructively based on one sole reflection. No need to deblock the lens.

PMD Modulo evaluates lenses on the fly with high resolution and without touching the lens. For the first time, on-the-block lens measurement occurs right after lens surfacing, avoiding the drastic time gap between manufacturing and quality inspection of current productions.

Maximum value is gained from the UV-PMD in conjunction with the LMS Modulo Cockpit. Integrating the PMD into the Modulo system opens up extensive new opportunities to analyze the collected data. The results are various new options and features that can considerably increase the value of your production line, e.g. a quality gate and quality trend recognition.
