Embodiment Construction

[0014] refer to figure 1 , 2 , the present invention is improved on the basis of the infrared image-changing tube. Compared with the structure of the infrared image-changing tube, it is completely the same except the silver oxycesium photocathode 3, the electrode cap 8 and the cone electrode 9 of the electron optical system. In terms of processing technology, they are identical except for the material of the cathode glass slide 2 and the production of the photocathode.

[0015] refer to figure 1 , 2 , explain the main technical solutions of the present invention: the present invention comprises cathode disk 1, cathode outer cylinder 4, cathode inner cylinder 5, glass cylinder 6, shielding cylinder 7, anode outer cylinder 10, anode disk 11, anode glass slide 12, fluorescent screen 13. Exhaust branch pipe A. The difference is: the cathode glass slide is a purple-infrared-transparent cathode glass slide 15 (purchased in the market, brand TZW, which can pass through 180-1400nm...

Abstract

The invention discloses an ultraviolet infrared image converter tube which is arranged on a night vision device as a core part and used for ultraviolet infrared observation and detection. The main technical scheme of the ultraviolet infrared image converter tube is that a cathode glass slide of the ultraviolet infrared image converter tube is an ultraviolet infrared transmitting cathode glass slide; an electronic optical system is an integral cone electrode; and a cathode is a silica cesium-oxygen-sliver photocathode. As proved by tests, the ultraviolet infrared image converter tube thoroughly overcomes the problem that a conventional infrared image converter tube has a single function. The ultraviolet infrared image converter tube makes the functions of an infrared image converter tube and an ultraviolet image converter tube integrated and becomes a composite image converter tube. The night vision device assembled by using the ultraviolet infrared image converter tube can have the using demands satisfied in different environmental conditions.

Description

technical field [0001] The invention relates to a photoelectric image transformation tube, in particular to a purple-infrared image transformation tube integrating ultraviolet and infrared images. As a core component, it is assembled on night vision devices, detectors, and distinguishers, and is used for ultraviolet detection, infrared detection, fingerprint identification, night observation, scientific research and criminal case investigation, etc. Background technique [0002] Existing infrared image changers (see figure 1 ) generally consists of cathode plate 1, cathode glass slide 2, silver cesium oxide (Ag-O 2 -Cs) Photocathode 3, cathode outer cylinder 4, cathode inner cylinder 5, glass cylinder 6, shielding cylinder 7, electrode cap 8, cone electrode 9, anode outer cylinder 10, anode disk 11, anode glass slide 12, fluorescent screen 13 and Exhaust branch pipe A and other components. Its working principle: when the infrared (wavelength 760-1200nm) image is incident ...
