Technical Examples

An optical component (10a) for at least two pencils (4, 5) of rays has at least one one-piece element (1, 2) of inorganic optical material and at least two segments (6, 7) which are coordinated with the pencils of rays and of which the first segment (6) is substantially surrounded by the at least one second segment (7). According to the invention, a depression (8a) is provided between the first and the at least one second segment (6 and 7), respectively. This is formed in such a way that the first segment (6) is substantially optically shielded from the at least one second segment (7) and is held by means of at least one material bridge from the second segment with a stable attitude thereto.
