Lumenizing ... An Important Four-Millionths Of An Inch Long before the war, Kodak began ^^surf ace coating^' the inner glass-air surfaces of its finer lenses with a microscopically thin transparent layer of magnesium fluoride about four-millionths of an inch thick. For all their superthinness, these coatings are a real help in photogra postal officials despair of their return. Such films find their way into a department of the Eastman Kodak Company, inRochester, where experts, with an ingenuity and tenacity rivalling that of the F.B.I., do their best to track down their man — the unknown movie maker. Some of their successes would make lively reading, but they prefer us to urge legible mailing instructions, and to remind you that present return-meuHng procedure calls for the insertion of the original film carton in a return "window" carton, with your own penmanship — and nothing else — appearing in that "window" for the guidance of the postman. If any of your film is ever missing, please write to the processing station to which it was sent, describing the type of film, whether 8mm. or 16mm., the approximate date it was sent in, and give some idea of its subject matter. (And eJso, incidentally, include your name and address.) ★ ★ ★ Today's full-scale movie making has resulted in a flood of Cine-KodeJcs and Kodascopes at dealers' and Kodak repair shops for touching up, inspection, or repairs — some needed, some imagined. Unless your equipment actually needs repedrs to put it in running condition, please do not forward it to a Kodak repair shop at this time. Use it now . . . send it along later this fall or winter. * ★ * All told, Cine-Kodak Film— Kodachrome, black-and-white, rolls, magazines, in various lengths — is suppUed for Cine-Kodaks in twentythree different cartons, SEALED AND DATED. Be certain you ask for and receive the type, size, and length of film your camera accepts. Otherwise, once the seed is broken, an awkward problem is posed for both dealers and Kodak, whose warranties are based upon supplying tested film in dated and sealed cartons. ' phy — aiding in killing reflections at the lens surface, reducing flare and avoiding ^^ghost" images, increasing light transmission, producing cleaner, crisper tone values in both highlights and shadows, resulting in better contrast in black-and-white movies and superior color purity with Kodachrome. ^ More recently, Kodak developed a magnesium fluoride coating so tough, and so well bonded to the glass of the lens, that it became practical to surfacetreat all glass-air surfaces — the exposed outer lens surfaces as well as the inner. Normal cleaning and polishing will not damage the coating — indeed, it's nearly as hard as the average optical glass and practically integral with the lens itself. Developed for and tested by war use, lenses so treated delivered the utmost quality of performance under rugged field conditions in all climates, and at sea. Kodak has given the label, ^^Lumenized,'' to all lenses so treated. Cine-Kodaks now being delivered are fitted with Lumenized lenses. Most Cine-Kodak accessory lenses are also Lumenized. Chances are that today any Cin^Kodak lens you buy will have received Lumenizing treatment — but please do not ask us to coat present lenses in your picture-making kit., .production schedules make it impossible. And remember that while Lumenizing does a real job of photographic trouble shooting, coating alone isn't a solution for defective optical systems. The care and skill that are part of the design and manufacture of every Cine-Kodak lens are as important as ever. EASTMAN KODAK COMPANY ROCHESTER 4, N.Y. Hf^
