Abstract
An optical sensor is configured to detect a difference in emissivity between the melt and a solid ribbon on the melt, which may be silicon. The optical sensor is positioned on a same side of a crucible as a cold initializer. A difference in emissivity between the melt and the ribbon on the melt is detected using an optical sensor. This difference in emissivity can be used to determine and control a width of the ribbon.
