In-Line Scanner for Recordable Optical Media: CD-R, DVD-R, DVD+R, DVD-R DL, DVD+R DL
First Choice of All Major Replicators Worldwide
Reliable quality assurance and process control for CD-R, DVD-R and DVD-R DL requires the integration of a series of dedicated ISM in-line scanner systems into replication lines. After molding, the Substrate Scanner ISM.sub inspects for local defects within and on the surface of clear substrates. The Dye Scanner ISM.dye controls the dye layer after the coating process. Finished discs are inspected by the Final Scanners.
The ISM.cd and ISM.dvd detect local defects at high speed and measure disc deformation with high precision. A specific inspection solution is available for DVD-R DL, including a unique dye scanner capable of inspecting both half discs, L0 and L1. Additional features include detection of Dye Splashes and Acceleration Defects, immediate solutions to an emerging need from replicators. Fast response to market needs is just another reason why major replicators choose Dr. Schenk in-line systems.
