VCC.ism-L+

high-resolution stamper and master inspection system enables continuous quality control of new and used masters and stampers for all optical disc formats.

The VCC.ism-L+ high-resolution optical inspection system is a quality assurance system for inspecting stampers and masters for all optical disc formats, including DVD-RAM with headers and MO with sector marks (optional). The automatic optical inspection is superior to the currently used visual or microscopic inspection, enabling a continuous and steady quality control of new and used stampers.

The inspection system consists of an optics head mounted in a stand-alone box and a connected PC for high-speed evaluation and visualization.

The stampers are retained on the turntable by magnetic force. Easily exchangeable center pins are provided to comply with different center hole sizes of the stampers. An additional centering unit is available for the inspection of glass masters. Optionally the inspection of stampers without center hole is possible.
