    "abstract": "This paper deals not with the optics of the photographic lens, motion picture projector, or studio illuminator, but rather with those instruments such as microscopes, photometers, etc., the use of which has contributed greatly to the advance of the motion picture art of today. A simple explanation is given of the different types of instruments and the general optical principles involved, and some of their specific applications, which indicate the debt which industry owes to optical science.",
