Abstract
An apparatus and method for automatically blocking and providing measurement of a lens blank during the blocking process includes an alignment station and a blocking station. The alignment station aligns a lens blank to a block for bonding that is also known as the blocking process. The blocking station includes a lens blank measurement system having sensors that automatically identify and determine measurement and alignment information about the lens, such as sag and tilt of the lens blank, during the blocking process.
