Электронно-оптическа  система содержит катод 1, модул тор 2, ускор ющий электрод 3, первый анод 4, фокусирующий электрод 5, перемычку 6, второй,чашечный .анод 7. К модул тору 2 и аноду 7 приварены монтажные скобы. Остальные электроды имеют на периферии штампованные аыстуоы ,, при помощи которых детали монтируютс  на штабики. Соосность электродов обеспечк|ваетс  центральным стержнем, который центрирует все детали по их внутренним диаметрам, а плоскопараллельность - спей серами . Предложенное соотношение между диаметром центральных отверстий и paccTOi ни ми между электродами обеспечивает лучшие услови  фокусировки при достаточно высокой электропрочности. В случае пр менени  такой электронно-оптической сие- темет рш кинескопа типа 61ЛК1Б рассто ни  между низковольтными и высоковольтными электродами по штабикам составл ет около 6 мм, что вполне достаточно дл  анодного напр жени  17 - 20 кВ. Формула из. обретени  Электронно-оптическа  система дл  крупногабаритного черно-белого кинескопа с одиночной линзой, содержаща  катод, модул тор , ускор ющий электрод, электрически соединенные первый и второй чашечный аноды и. фокусирующий электрод, отличающа с  тем что, с целью повышени  технологичности и снижени  стоимости иэ готовленн , ускор ющий, фокусирующий электроды и первый анод выполнены в виде плоских Диафрагм с отверсти ми равного диаметра, при этом рассто ни  между ускор ющим электродом н первым анодом, а также между анодом и фокусаруюшнм электродом оавны диаметру отверстий, а рассто ние между фокусирук щкм электродом и вторым чашечным анодом составл ет 1/3 диаметра отверстий. Источники информации, прин тые во внимание при экспертизе: 1.Шерстнев Л. Г. Электронна  оптика и электронно-лучевые приборы , Энерги , 1971 с. 196-199. The electron-optical system contains a cathode 1, a modulator 2, an accelerating electrode 3, a first anode 4, a focusing electrode 5, a jumper 6, a second cup plate. 7. The mounting brackets are welded to the modulator 2 and anode 7. The rest of the electrodes are stamped with aystuoy on the periphery, with the help of which the parts are mounted on bars. The coaxiality of the electrodes is ensured by the central rod, which centers all the parts according to their internal diameters, and the plane-parallelism - by spiers. The proposed relationship between the diameter of the central holes and the pacctoi between the electrodes provides the best focusing conditions at a sufficiently high electrical strength. In the case of the use of such an electron-optical system of a PNL 61LK1B type kinescope, the distance between low-voltage and high-voltage electrodes at the cores is about 6 mm, which is quite enough for an anode voltage of 17-20 kV. Formula from. Electron-optical system for a large-sized black-and-white kinescope with a single lens, containing a cathode, a modulator, an accelerating electrode, electrically connected first and second pan anodes and. a focusing electrode, characterized in that, in order to increase manufacturability and reduce the cost, the ready, accelerating, focusing electrodes and the first anode are made in the form of flat diaphragms with holes of equal diameter, while the distance between the accelerating electrode and the first anode is also between the anode and the focal electrode is equal to the diameter of the holes, and the distance between the focusing electrode and the second cup anode is 1/3 of the diameter of the holes.
