Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] see figure 1 , which is a schematic diagram of the composition and structure of the solar-blind gas-filled ultraviolet detector 100 provided by the embodiment of the present invention. The solar-blind gas-filled ultraviolet detector 100 includes a molybdenum-group transparent purple glass envelope 10 and a stem 20 housed in the molybdenum-group transparent purple glass bulb 10 .

[0042] The shape of the molybdenum-group transparent purple glass bulb 10 is similar to that of a common test tube. One end is a crown-shaped closed end 12 and the other end is a circular open end 14 . The molybd...

Abstract

The invention relates to a sun-blind gas-filled ultraviolet detector, which includes a core column and a molybdenum-group transparent purple glass shell for accommodating the core column and sealing with the core column as a whole. The core column includes an anode, a cathode, and a row The air pipe and the anode support rod lead-out wire and the cathode support rod lead-out wire in the stem column are installed. One end of the lead-out line of the anode support rod extends into the molybdenum-group transparent purple glass envelope and is connected with the anode; one end of the lead-out wire of the cathode support rod extends into the molybdenum-group transparent purple glass envelope and is connected with the photocathode. The photocathode is in a hemispherical shape, and one end of the lead-out wire of the anode rod protruding into the molybdenum group transparent glass envelope is bent into a curved shape to make the anode. The sun-blind gas-filled ultraviolet detector has better sensitivity because its hemispherical photocathode has a larger contact area. The invention also relates to a manufacturing method of the sun-blind gas-filled ultraviolet detector.

Description

technical field [0001] The invention relates to a detector and a manufacturing method thereof, in particular to a sun-blind gas-filled ultraviolet detector and a manufacturing method thereof. Background technique [0002] Flame radiation is gas radiation with discrete spectrum and solid radiation with continuous spectrum. Its wavelength is in the range of 0.1-10 μm or wider. In order to avoid the interference of other signals, ultraviolet rays with a wavelength of <300nm are often used, or unique in flames. The CO2 radiation spectrum with a wavelength around 4.4 μm is used as the detection signal. The gas-filled ultraviolet detector only responds to ultraviolet rays in a narrow range of 185nm to 260nm, but is insensitive to light in other spectral ranges. It can be used to detect ultraviolet rays in flames. The sunlight reaching the ground below the atmosphere and the non-purple-transparent material used as the electric light source of the glass bulb emit light with a wa...
