Embodiment
Below in conjunction with accompanying drawing the utility model is specifically described, as Fig. 1 is the structural representation of incorporated light photoelectric direct reading spectrometer described in the utility model, as shown in the figure, a kind of incorporated light photoelectric direct reading spectrometer, comprise thermostatic machine case 1, excitation chamber 2 and light-splitting chamber 3 lay respectively at the left and right sides of cabinet internal partition 4, and the cabinet dividing plate is provided with condenser 5, the single-chip microcomputer 6 that is positioned at thermostatic machine case is electrically connected with light-splitting chamber by measurement and control unit 7, and single-chip microcomputer is electrically connected with thermostatic machine case host computer 19 outward.Wherein, described excitation chamber is by placing exciting platform 8, face the LASER Light Source 9 that excites sample on the platform and guaranteeing that to exciting platform to charge into argon gas non-oxidizing purification for argon device 10 3 parts of sample constitute of sample; Be provided with entrance slit 20 and concave grating 11 in the described light-splitting chamber, condenser, entrance slit and concave grating place on the input path, all be provided with exit slit 12 on many spectral line light paths by the concave grating reflection, it is on the deep-slotted chip breaker 21 at center with the spill grating that entrance slit and exit slit all are installed in light-splitting chamber interior, and each exit slit back all faces toward a photomultiplier 13; The place ahead of described concave grating is fixed with tired lamp 14; Evacuator 15 also is installed in the described light-splitting chamber; Described photomultiplier is electrically connected with measurement and control unit respectively; Described measurement and control unit is connected and composed successively by signal amplification circuit 16, filtering circuit 17 and A/D converter 18.
In the technical program, optical system is installed in the light-splitting chamber, optical system is made up of condenser, entrance slit, concave grating, tired lamp, exit slit and photomultiplier.Light-splitting chamber places in the cabinet of local constant temperature, to guarantee the stable of optical system.
On the condenser fitting machine separator for container, it separates light-splitting chamber and arc-spark stand.The mixed light that sends after sample is excited mainly is to strengthen the slit illumination effect by condenser optically focused (having the effect of sealing light-splitting chamber concurrently) irradiation entrance slit.
Be object-image relation between entrance slit and the spectral line.The quality of entrance slit and the quality of spectral line have direct relation, and its width is 20 ± 3 μ m.Entrance slit can move reciprocatingly along the tangential direction of Rowland circle under computer control, realizes the scanning of spectral line to the exit slit relative position.Concave grating is the cardiac component of beam splitting system, and main effect is beam split and imaging.Its bearing accuracy is very important, has done accurate adjustment before instrument dispatches from the factory, and has adopted reliable connected mode, even there is very big vibration also can not change its position.Therefore device operator need not be carried out any adjustment to grating, and bans the use of any article and touch the grating ruling face.Attention: even displacement has taken place grating, the operator oneself does not adjust yet, and can only be reorientated with instrumentation by experienced personnel by manufacturer.
There is a miniature lamp in concave grating the place ahead, and it is powered specially by measurement and control unit.Light at off position at ordinary times always, be used for photomultiplier is carried out cathode fatigue, therefore be commonly called as tired lamp.Lighting or extinguishing of tired lamp controlled by measurement and control unit.
Exit slit is installed on the Rowland circle track, and its width has three kinds of 35 μ m, 55 μ m and 75 μ m, and its position was transportable before determining.It and selected analysis spectral line have been aimed at before instrument dispatches from the factory, and be securely fixed on the Rowland circle track, do not needed the user to adjust generally speaking.
Corresponding each exit slit all is equipped with a photomultiplier, and it converts light signal to the corresponding current signal of intensity with it under the effect of high direct voltage.
In order to ensure safety, sample connects negative pole and idiostatic with the earth in excitation chamber, and electrode connects positive pole.One condenser is housed between spark platform and light-splitting chamber, becomes the boundary of light-splitting chamber and arc-spark stand, both strengthened illumination, stop air, argon gas to be leaked to light-splitting chamber again entrance slit.
Argon gas is the protection gas of excitation process, and it washes away the air of spark chamber (discharging gap), so that sample surfaces is not oxidized, can avoid the absorption of oxygen to shortwave radiation simultaneously.Even work as instrument in waiting status, the argon cleaning spark chamber of 1L/min flow also should be arranged.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art to some part wherein some changes that may make all embodied principle of the present utility model, belong within the protection domain of the present utility model.
