Description
Изобретение относитс к области элект ронной техники, а именно к изготовлению экранов ЦЭЛТ со щелевыми масками.The invention relates to the field of electronic engineering, in particular to the manufacture of CELT screens with slit masks.
Известно устройство дл фотоэкспони- ровани матричных экранов .5A device for photoexposure of matrix screens is known .5
Световод в известном устройстве имеет такую конструкцию излучающей головки, что при использовании масок щелевого типа не позвол ет получать сплошные люм№нофорные линии требуемой ширины без пе-Ю ремычек.The light guide in the known device has such a design of the radiating head that, when using slit-type masks, it does not allow to obtain continuous luminous lines of the required width without translucent straps.
Известно также устройство дл фотоэкспо8 (ировани экранов ЦЭЛТ с линейчатой структурой со щелевыми масками, включающее в себ источник света, отра- 5 жатель и световод клинообразной формы с выходным торцом Г 23.A device for photoexposing8 is also known (emitting CELT screens with a linear structure with slit masks, which includes a light source, a reflector and a wedge-shaped light guide with an output end G 23.
В известном устройстве у кварцевого Световода большие стороны выполнены в виде плоских поверхностей, а выходной тор1ец имеет пр моугольную форму. Исполь зование такого кварцевого световода дл экспонировани люминофорных покрытийIn the known device, a large side of a quartz fiber is made in the form of flat surfaces, and the output face has a rectangular shape. The use of such a quartz fiber to expose phosphor coatings
на экранах ЦЭЛТ со щелевыми масками не позвол ет получать сплошные люмкнофорные линии заданной ширины из-за огсутстви необходимого. Распределени оовещенности по всей поверхности экрана и в световом п тне.on CELT screens with slit masks, it is not possible to obtain continuous lumophore lines of a given width due to the presence of the necessary. Distribution of alert over the entire surface of the screen and in the light spot.
Кроме того, така конструкци световода требует применени сложных методов дополнительного выравнивани освещенности на поверхности экрана, ввиду большого коэффициент отношени освещенности в центральной зоне к кра м.In addition, such a fiber design requires the use of complex methods of additional alignment of the illumination on the screen surface, due to the large ratio of the illumination in the central zone to the edges.
Цель изобретени - получение сплошных люминофорных линий заданной ширины и получение равномерного распределител освещенности в световом п тне.The purpose of the invention is to obtain continuous phosphor lines of a given width and to obtain a uniform irradiance distributor in the light spot.
Поставленна цель достигаетс тем, что в устройстве дл фотоэкспонировани экранов ЦЭЛТ боковые поверхности световода вьтолнены в виде вогнутых плавно Сопр женных поверхностей, а также тем, боковые поверхности световода вл ютс результате пересечени , например.This goal is achieved by the fact that in the device for photoexposure of CELT screens, the side surfaces of the fiber are made in the form of concave smoothly Coupled surfaces, and also the side surfaces of the fiber are the result of intersection, for example.
