A lens holder subassembly is described which essentially consists of a first and a second holding element having screw threads between them which enable axial displacement of the holder elements by a relative rotation between them; the lens holder subassembly is produced in a casting process in which one of the holder elements is used as a mould element in the production of the other holder element, the other holder element being produced by injection moulding of resin material which is injected into a cavity bounded at least partially by the first holder element. The lens holder subassembly is produced with the holder element in the operating position when they are removed from the hollow mould. |
