Blu-Ray Competence: Quality Assurance & Process Control

Dr. Schenk, known as the inspection pioneer for the optical media industry, continues to set standards also for the generation III of high definition formats. Blu-ray disc replicators and manufacturers rely on the quality assurance and process control systems that have "precision in focus".

The perfect synergy between technical innovation, more than 3 decades of experience in optical design, close relation and collaboration with major developers of the new media format as well as a solid and growing organization builds the basis for Dr. Schenk's Blu-ray competence and business success.

Instead of just an upgrade of a standard DVD scanner, a completely new optical set-up, including high-speed electronics, has been developed to fulfill the special needs of BD inspection. The unique optical design of the In-Line scanner ISM.blue+ and the Off-Line system PROmeteus MT-200.blue enables a reliable inspection and process control that meet the strict quality standards of Blu-ray disc production at an optimized yield.
