Embodiment
Advantage of the present utility model is set forth further below in conjunction with accompanying drawing and specific embodiment.
Consult Fig. 1, in the utility model, in order to produce the light-configuration mode of multiple emergent light to single light source, at the light-emitting window of a laser beam emitting device (not shown), be provided with a spectral module 100, wherein this spectral module 100 comprises:
-condenser lens 110, be arranged on the light-emitting window of laser beam emitting device, the laser that laser beam emitting device produces is focused on by this condenser lens 110, to remove veiling glare, and produce parallel rays, after the laser that laser beam emitting device produces simultaneously passes through condenser lens 110, produced the convergence light 111 of an outgoing by condenser lens 110;
-the first catoptron 120 and the second catoptron 130, after being arranged on condenser lens 110, and is arranged in the light path of convergence light 111, thus convergence light 111 can be reflected.In the present embodiment, in order to produce two laser spots, convergence light 111 not all reflects by the first catoptron 120 or the second catoptron 130, and only the part converging light 111 is reflected.Particularly, first catoptron 120 and the second catoptron 130 are arranged on the laser optical path of convergence self neighboring of light 111 or dual-side, after then convergence light 111 shines the position of the first catoptron 120 and the second catoptron 130, converge the both sides laser of light 111 or neighboring laser to be peeled off by the first catoptron 120 and the second catoptron 130 respectively and by external reflection, and in the middle part of the convergence light 111 that the first catoptron 120 and the second catoptron 130 are not in the part of light path by still along original optical path outgoing, this middle part along the convergence light 111 of original optical path outgoing is a central ray 141.Under this arrangement, converge light 111 and be divided into three parts by this first catoptron 120 and the second catoptron 130, be respectively the first reflection ray 121 reflected by the first catoptron 120, the second reflection ray 131 reflected by the second catoptron 130, and all not by central ray 141 that the first catoptron 120 and the second catoptron 130 reflect, wherein the first reflection ray 121 of the first catoptron 120 and the reflection of the second catoptron 130 and the reflection direction of the second reflection ray 131 inconsistent, this first reflection ray 121 and the second reflection ray 131 are projected after on object and forms two laser spots.First the light of single light source is produced as the light that can produce two laser spots by two independent catoptrons, is understandable that, under in such a configuration, has just saved a light source;
-cylindrical mirror 140, be arranged on not by the light path of central ray 141 that reflects, central ray 141, when not by cylindrical mirror 140, still exists with the light form that can produce laser spots, after cylindrical mirror 140, form by cylindrical mirror 140 scattering the light that one can produce a laser rays on object.
Thus, the light of single light source is divided into the form that can produce two laser spots and a laser rays by the spectral module 100 with the utility model configuration, and come from same light source due to the laser spots that produces and the source light of laser rays, the laser spots then produced and the frequency of laser rays, light intensity etc. are basically identical, can not cause inapplicable problem in practical operation due to the change of light splitting form.
In one preferred embodiment, first catoptron 120 and the second catoptron 130 are 45 ° of angles with converging light 111, thus the light after the first catoptron 120 and the reflection of the second catoptron 130 is 90 ° of angles with converging light 111 and being positioned at the central ray 141 converged in the middle part of light 111, just can be used on the photoelectric instrument that needs to produce mutually perpendicular laser electric wire, and the first reflection ray 121 and the second reflection ray 131 can not interact, intersect, and avoid the generation of unnecessary hot spot.
In above-described embodiment, also alternatively the position of the first catoptron 120 and the second catoptron 130 is configured to: with central ray 141 for rotational symmetry is arranged, then the first reflection ray 121 and the second reflection ray 131 are also symmetrical relative to central ray 141, make the bright dipping of two laser spots of spectral module 100 symmetrical mutually, the position conveniently with the light-emitting window of the photoelectric instrument of this spectral module 100 is arranged.
In order to save spectral module 100 and even photoelectric instrument taken up space, the volume of spectral module 100 is needed to reduce as much as possible, therefore, the distance of the first catoptron 120 and the second catoptron 130 to condenser lens 110 can be configured to the distance equaling cylindrical mirror 140 to the first catoptron 120 and the second catoptron 130, also or any one or two that reduce in the distance of the distance of above-mentioned first catoptron 120 and the second catoptron 130 to condenser lens 110, cylindrical mirror 140 to the first catoptron 120 and the second catoptron 130.Those of skill in the art would appreciate that above-mentioned two will cause irreflexive situation to produce apart from too small, excessive then can Attenuated laser light intensity, therefore, in actual use, should Operating condition adjustment be looked.
In order to ensure the first reflection ray 121 further, the light intensity of the second reflection ray 131 and central ray 141, frequency is consistent, the installation site of the first catoptron 120 and the second catoptron 130 can be peeled off respectively and be converged 1/3rd of light 111, make the first reflection ray 121, second reflection ray 131 and central ray 141 are respectively the trisection light converging light 111, thus the laser spots of the first reflection ray 121 and the generation of the second reflection ray 131 is in the same size, the width of the laser rays of central ray 141 after cylindrical mirror 140 and the consistent size of laser spots, to meet higher request for utilization.
Be understandable that equally, first catoptron 120 and the second catoptron 130 are the light microscopic that is all-trans, the part of the convergence light 111 through the first catoptron 120 and the second catoptron 130 is all reflected, do not do transmission, clearly divide the first reflection ray 121, second reflection ray 131 and central ray 141.
Spectral module 100 in above-mentioned any embodiment all can use in laser level, to produce the luminous intensity distribution form of two laser spots one laser rays mentioned above, and owing to only using single light source to produce, assembly cost and the corresponding reduction of requirement of light regulation, optimize the one-piece construction of laser level.
Should be noted that, embodiment of the present utility model has preferably implementation, and not any type of restriction is done to the utility model, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement change or be modified to equivalent effective embodiment, in every case the content of technical solutions of the utility model is not departed from, the any amendment done above embodiment according to technical spirit of the present utility model or equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
