Abstract
A pair of moulds for moulding an optical component is disclosed. The pair of moulds includes a first mould having a first surface, and a second mould having a second surface. The first surface includes a moulding portion for moulding a first optical surface of the optical component, and an alignment portion for alignment with the second mould. The alignment portion extends around the moulding portion. The second surface includes a moulding portion for moulding a second, opposite optical surface of the optical component, and an alignment portion for alignment with the first mould via a contact with the alignment portion of the first surface. When the moulds are brought together, they self-align. A corresponding moulding apparatus and a method may use the mould pair to manufacture various optical components.
