Abstract
A method and apparatus for measuring a melt back of a seed in a boule are provided. The method includes lifting a boule once it has been produced using an actuating device onto a support table to automatically manipulate the boule from a furnace to the support table. The melt back of the seed is then automatically measured using a vision system that is installed on an imaging device disposed below the boule.
