Its operation principle: target is under the irradiation of infrared light, the infrared image of reflection is incident on the image converter tube photocathode face, excite photocathode, make photocathode produce corresponding with it electronic image, this electronic image compiles, disperses and quicken through image converter tube high pressure, static sub-lens system, bombardment image converter tube phosphor screen makes it to produce a corresponding visible optical image of the infrared image with incident, watches for human eye.
Its main performance index: infrared light sensitivity 5 μ A/lm, center resolution 60Lp/mm, edge resolution 16Lp/mm, distortion 14%, magnification ratio 0.95-1.05 (doubly), dark current 0.02 μ A, operating voltage 12KV.
This image converter tube volume is little, in light weight, easy to use.But do not find as yet up to the present at home and can oneself make that original structure was also once repeatedly attempted to adopt fully by the colleague unit that has, and made this image converter tube with home equipment and conventional manufacture method, all not success.Using all is to rely on external import, because price is very expensive, be not suitable for China's national situation.
Three, summary of the invention
The main technical problem to be solved in the present invention and purpose are: the basic structure with 8598 pipes is foundation, improving on the partial structurtes and in the making of several vitals, provides a kind of new small-size infrared image converter tube.
Main technical schemes of the present invention: 1, product structure aspect, the ping-pong ball in A, the steaming silver group is divided into uniformly at 3 and is connected on the lead-in wire.In B, the glass tube group, on glass tube circumference, establish two lead-in wires.The getter of C, getter group is a toroidal, is installed on the image converter tube axial location.Set up an electrode cap on D, the external electrode.2, manufacture method aspect, tube outer surface is made a glassy layer in big negative electrode.
After the improvement of the present invention by structure and manufacture method, made image converter tube satisfies instructions for use fully, tries out from army, public security and scientific research, fully can substituting import one, and part also exports some developing countries.Its basic mechanical design feature index: Φ 30 * 42 (maximum outside diameter * length), infrared light sensitivity 5 μ A/lm are above, center resolution 60Lp/mm, edge resolution 16Lp/mm, distortion 14%, 1 ± 0.05 times of magnification ratio, infrared luminance gain more than 3.8 times, dark current 0.02 μ A, operating voltage 12KV, and all leading indicators have reached or have been better than 8598 image converter tubes.

Five, embodiment
Describe in further detail below in conjunction with the embodiment of accompanying drawing the present inventor:
Substantially form by negative electrode slide 1, photocathode 2, cathode flange dish 3, negative electrode urceolus 4, little negative electrode inner core 5, big negative electrode inner core 6, interior electrode 7, steaming silver group 8, glass tube group 9, external electrode 10, getter group 11, anode urceolus 12, screen slide 13, screen ring flange 14, arm 16, electrode cap 17 with reference to Fig. 2, the present invention.
Its operation principle is the same.
1, the present invention is in the improvement of configuration aspects
Problems such as with reference to Fig. 3,4, steaming silver is organized the ping-pong ball in 8, is divided into uniformly at 3 and is connected on the lead-in wire, and it is inhomogeneous effectively to have solved making photocathode steaming silver, and cathode sensitivity is not high.Former 8598 pipes, ping-pong ball divides point-to-point transmission to be connected on the lead-in wire every 180 °.
With reference to Fig. 6, in the glass tube group 9, on glass tube circumference, establish two lead-in wires, be used to improve electric conductivity.Former 8598 pipes are established 3 lead-in wires on glass tube circumference.
With reference to Fig. 5,6, the getter in the getter group 11 is circular, is installed on the axial location of image converter tube, is used to reduce solder joint, corner angle, minimizing discharge.The getter of former 8598 pipes is an elongated cylindrical.
With reference to Fig. 2, set up an electrode cap 17 on the external electrode 10, be used to reduce the potential difference of solder joint, solve image converter tube high pressure weak discharge problem.
2, the improvement of the present invention on manufacture method
With reference to Fig. 2, on big negative electrode inner core 6 outer surfaces, make one deck glassy layer, mainly increase the dielectric strength between big negative electrode inner core 6 and interior electrode 7, the external electrode 10, solve the problem of discharge.Its process for making: (1), with Dm-305 optical glass grind into powder; (2), will screen the good an amount of nitrocellulose solution of glass dust adding stirs in the pasty state; (3), the frit for preparing is coated in big negative electrode inner core 6 surfaces; (4), coated big negative electrode inner core 6 is placed in the luxuriant good fortune stove, be warming up to 600 ℃ and carry out roasting, then reduce to 20 ℃; (5), the big negative electrode inner core 6 that roasting is good carries out vitreous and handles, and big negative electrode inner core is put into coreless induction furnace, heat to glass when melting, drop to 20 ℃; (6), clean.The big negative electrode inner core of former 8598 image converter tubes 6 surfaces are to scribble one deck chrome green, and are serious by the sample discharge that its method produces, and do not reach specification requirement.
With reference to Fig. 2,5, photocathode 2 is made up of silver, oxygen, caesium.When making photocathode 2, wherein steaming the caesium operation is external steaming method, and its concrete practice is: cesium chloride and calcium are contained in the caesium bubble of arm 16, as caesium source 15, with the roasting caesium bubble of fire, generation caesium steam enters pipe interior focusing electricity negative electrode and steams, after photocathode was finished, the caesium bubble prescinded together with arm.Other operation repeats no more here as conventional operation.Solved the restive problem of caesium amount like this, cathode sensitivity is also corresponding to be improved, and has also simplified the pipe inner structure simultaneously, is beneficial to and improves performance.Former 8598 image converter tubes are steaming methods in adopting, and caesium chromate is wrapped with the nickel metal skin, and it is interior as caesium source 15 to be fixed on pipe, and after photocathode was finished, shell was stayed in the pipe.The photocathode of according to said method making does not reach specification requirement.
