Abstract
The utility model provides a fixed combined light source for a spectrometer, and the problem to be resolved is that the service life of the hollow cathode lamp of the prior light source for instruments becomes shorter. The fixed combined light source has the following characteristics: a hollow cathode lamp and a tungsten lamp are fixed on a lamp holder, and a planar mirror is then arranged opposite to the hollow cathode lamp and the tungsten lamp; a planar mirror which is driven by a motor to rotate is arranged at the center of a mirror holder, so that the light emitted by the hollow cathode lamp or the tungsten lamp can be reflected to a concave mirror and is then reflected by the concave mirror to a half-transparent half-reflecting mirror; a deuterium lamp is arranged in the light source, the emitted light is reflected by the planar mirrors to the concave mirror and then reflected by the concave mirror to the half-transparent half-reflecting mirror, and the beam-combined light is emitted out through color filters or holes without the color filters on a color filter holder. The utility model has the following advantages: since the hollow cathode lamp and the tungsten lamp are fixed on the lamp holder, the service lives of the hollow cathode lamp and the tungsten lamp can be prolonged; and the arrangement of the tungsten lamp broadens the use range of the instrument.
Description
Technical field
The utility model relates to a kind of light source in the multiple optic analytical instruments such as being applied to Atomic Absorption Spectrometer, atomic fluorescence spectrometer, specifically be a kind of fixed, broadband, can change the light supply apparatus of lamp position automatically.
Background technology
The technology of the analytical instrument of China is flourish at present.But, existing light source for instrument exist automatic degree low, install that the hollow cathode lamp number is few, wavelength available scope weak point, unreasonable structure, some problems such as cause that hollow cathode lamp longevity shortens.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of this utility model provide a kind of fixed, broadband, can change the fixed type combined light source of spectrograph of lamp position automatically, it can be applied in the multiple spectral instruments such as atomic absorption spectrophotometer (AAS) and atomic fluorescence spectrophotometer.
The purpose of this utility model is achieved in that hollow cathode lamp 4 and tungsten lamp 13 is fixed on the lamp bracket 12, on the opposite of hollow cathode lamp 4 and tungsten lamp 13 level crossing 2 is set again, this level crossing tilts to be installed on the mirror holder 14, the light that this inclination can make hollow cathode lamp 4 or tungsten lamp 13 send is mapped to the mirror holder center through level crossing 2; At the mirror holder center level crossing 3 of using motor 1 driven in rotation is set, the light of selecting hollow cathode lamp 4 or tungsten lamp 13 to send by rotation is mapped to concave mirror 11, reflexes to semi-transparent semi-reflecting lens 10 by concave mirror 11 again; Deuterium lamp 9 is set again in light source simultaneously, the light that deuterium lamp 9 emits reflexes to concave mirror 6 through level crossing 5, reflex to semi-transparent semi-reflecting lens 10 by concave mirror 6 again, like this by the light of hollow cathode lamp 4 or tungsten lamp 13 and the light of deuterium lamp 9, in semi-transparent semi-reflecting lens 10 place's energy in half and close bundle.Close light behind the bundle again through the color filter 7 on the color filter frame 8 or do not have the colour filter film perforation and penetrate, to reach the needs of different checks.
Compared with prior art, the beneficial effects of the utility model are: hollow cathode lamp 4 and tungsten lamp 13 are for being fixed on the lamp bracket 12, and this design can improve the life-span of hollow cathode lamp 4 and tungsten lamp 13.Tungsten lamp 13 the usable range that has increased instrument is set.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.

Fig. 2 is the integrated synoptic diagram that are installed to lamp box of each parts of the utility model.
Embodiment
Referring to Fig. 1, hollow cathode lamp 4 and tungsten lamp 13 are fixed on the lamp bracket 12, on the opposite of hollow cathode lamp 4 and tungsten lamp 13 level crossing 2 are set again, this level crossing tilts to be installed on the mirror holder 14, the light that this inclination can make hollow cathode lamp 4 or tungsten lamp 13 send is mapped to the mirror holder center through level crossing 2; At the mirror holder center level crossing 3 of using motor 1 driven in rotation is set, the light of selecting hollow cathode lamp 4 or tungsten lamp 13 to send by rotation is mapped to concave mirror 11, reflexes to semi-transparent semi-reflecting lens 10 by concave mirror 11 again; Deuterium lamp 9 is set again in light source simultaneously, the light that deuterium lamp 9 emits reflexes to concave mirror 6 through level crossing 5, reflex to semi-transparent semi-reflecting lens 10 by concave mirror 6 again, like this by the light of hollow cathode lamp 4 or tungsten lamp 13 and the light of deuterium lamp 9, in semi-transparent semi-reflecting lens 10 place's energy in half and close bundle.Close light behind the bundle again through the color filter 7 on the color filter frame 8 or do not have the colour filter film perforation and penetrate, to reach the needs of different checks.Be installed to (referring to Fig. 2) in the lamp box 15 with each parts of 1-14 are integrated at last.
