High-temperature solar blind ultraviolet photoelectric tube and manufacturing method thereof

Abstract

The invention discloses a high-temperature solar blind ultraviolet photoelectric tube and a manufacturing method thereof. The photoelectric tube comprises a core column, a molybdenum group purple glass permeable shell, a metal straight rod and a molybdenum electrode, wherein the molybdenum group purple glass permeable shell is encapsulated on the core column; the metal straight rod is arranged in the core column; and the molybdenum electrode is connected to the metal straight rod. When the high-temperature solar blind ultraviolet photoelectric tube exhausts air, the molybdenum group purple glass permeable shell is baked at high temperature for a long time and the molybdenum electrode is treated by an electron bombardment method. The photoelectric tube has the advantages of high sensitivity, high reliability, long service life, high response speed, high temperature resistance, no response to visible light and infrared light, light weight and the like.

Description

technical field [0001] The invention relates to the field of photoelectric tubes, in particular to solar-blind ultraviolet photoelectric tubes capable of working at a high temperature of 250°C, in particular to a high-temperature solar-blind ultraviolet photoelectric tube and a manufacturing method thereof. Background technique [0002] Modern warfare is a high-tech warfare, and it is particularly important to strive for air supremacy and long-range strikes. A large number of various fighter groups and missiles with excellent performance are the main tools for air strikes, and the normal and stable operation of aero-engines plays a very important and key role. At present, fighter jets in developed countries in the United States and Europe have adopted photoelectric detection systems to monitor the working conditions of aeroengines, and sun-blind ultraviolet photoelectric tubes are indispensable key components in this detection system. At present, the general working tempera...
