This paper gives a survey of the activities in the Federal Republic of Germany - from spectacle lens optics through photographic optics to astronomical and X-ray optics. The production techniques employed - grinding with loose abrasive, machining with bonded grain, single-point diamond turning and copying techniques - are discussed. Testing techniques which play an important part in production can only be touched on in passing.
