Abstract: An apparatus and a method for deblocking a lens, wherein the lens is blocked with a block material on a block piece. The block material is preheated by radiation. The blocked lens, the deblocked lens, and the deblocked block piece are handled by means of separate grippers. For deblocking, the lens and the block piece are held by opposing holding devices in a rotating manner, while a fluid jet acts on the block material from the side. After the deblocking, the lens and the block piece are cleaned simultaneously. Then, a holding device together with the deblocked lens pivot out from a working space. The deblocked lens is placed with the block side upward in a transport carrier. This makes possible a simple design and an optimized process sequence.

Abstract: An optical arithmetic-logical unit [“ALU”] processes one or more combined input signals, which result from a combination of multiple elementary input signals, each of which comprises at least one polarization component. One of the combined input signals is a synchronization signal having a phase and an amplitude. At least one laser has an output and is configured to synchronize with the synchronization signal, wherein the synchronization of the laser with the synchronization input signal generates an output signal, which preserves the phase of the synchronization signal but normalizes its amplitude. Generation of the output signal by said normalization of the synchronization signal provides the ALU with a capability of performing one or more arithmetic-logical operations on the one or more combined input signals.
