Abstract
An apparatus and a block mold for blocking a lens are proposed, wherein the lens is blocked on a block piece by means of a block material. The space between the lens and the block piece is laterally delimited by a block mold. The block mold is preferably plate-shaped and has a plurality of block openings for forming different block sizes and has an integrated coolant channel. This enables easy and fast changing between different block sizes and very good cooling.
