Abstract
The utility model relates to a spectrum lamp comprising a spectrum lamp body filled with rare gas, wherein the spectrum lamp body comprises two parallel electrode tubes, a light-emitting tube is communicated between the two electrode tubes, and electrodes are respectively arranged in the two electrode tubes. The spectrum lamp can be widely applied to optical instruments such as refractometers, interferometers and the like.
Description
Technical field
The utility model relates to the technical field of lamp, especially a kind of spectroscopic lamp that is filled with helium.
Background technology
In places such as school or physics Institute, the researcher usually need go to study certain physical characteristics by optical instruments such as refractometer, interferometers.
The utility model content
The technical problems to be solved in the utility model is: the utility model provides a kind of and is widely used in the optical instruments such as refractometer, interferometer, as the spectroscopic lamp of monochromatic source use.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of spectroscopic lamp, have the spectroscopic lamp body that is filled with rare gas, and described spectroscopic lamp body comprises two parallel electrodes pipes, is communicated with luminous tube between two electrode tubes; Be provided with respectively in two electrode tubes an electrode is installed.
Further, rare gas is helium or neon or argon gas or krypton gas or xenon or radon gas.
Further, inside diameter D capillaceous is 1～2mm.
Further, the electrode that is separately positioned in two electrode tubes is a nickel system electrode.
Further, luminous tube can be communicated with the place, centre position at two electrode tubes, also can be the apical position place.
Further, luminous tube 2 is linear or circular arc or S shape.
The beneficial effects of the utility model are that spectroscopic lamp of the present utility model is widely used in the optical instruments such as refractometer, interferometer, uses as monochromatic source, sends the characteristic spectral line of helium.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, electrode tube, 1-1, electrode, 2, luminous tube.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of spectroscopic lamp as shown in Figure 1 has the spectroscopic lamp body that is filled with rare gas, and described spectroscopic lamp body comprises two parallel electrodes pipes 1, is communicated with luminous tube 2 between two electrode tubes 1; Be provided with respectively in two electrode tubes 1 an electrode 1-1 is installed.
Wherein rare gas is helium or neon or argon gas or krypton gas or xenon or radon gas; The inside diameter D of luminous tube 2 is 1～2mm; The electrode 1-1 that is separately positioned in two electrode tubes 1 is a nickel system electrode; Luminous tube 2 can be communicated with the place, centre position at two electrode tubes 1, also can be the apical position place; Luminous tube 2 is linear or circular arc or S shape.
This lamp is a cold-cathode glow discharge valve, behind the build-up of luminance that adds high pressure, sends the characteristic spectral line of helium, spuious the intensity of spectral line in its vicinity be not more than its 10%.
