Embodiment

Advantages of the present invention is expanded on further below in conjunction with accompanying drawing and specific embodiment.

Refering to Fig. 1, in of the invention, in order to produce the light-configuration mode of multiple emergent lights to single light source, filled in a Laser emission The light-emitting window of (not shown) is put, provided with a spectral module 100, the wherein spectral module 100 includes：

- condenser lens 110, the light-emitting window of laser beam emitting device is arranged on, laser caused by laser beam emitting device is gathered by this Focus lens 110 are focused, and to remove veiling glare, and produce parallel rays, at the same laser caused by laser beam emitting device pass through it is poly- After focus lens 110, the convergence light 111 of an outgoing is produced by condenser lens 110；

- the first speculum 120 and the second speculum 130, after being arranged on condenser lens 110, and it is arranged on convergence light 111 Light path on, so as to will convergence light 111 reflected.In the present embodiment, in order to produce two laser spots, the first speculum 120 or second speculum 130 not will all reflections of convergence light 111, and only the part for converging light 111 is reflected. Specifically, the first speculum 120 and the second speculum 130 are arranged on the laser of convergence itself neighboring of light 111 or two sides In light path, then after convergence light 111 is emitted to the position of the first speculum 120 and the second speculum 130, convergence light 111 Both sides laser or neighboring laser are peeled off and by external reflectance by the first speculum 120 and the second speculum 130 respectively, and first The part for the middle part light path of convergence light 111 that the speculum 130 of speculum 120 and second is not in by being still emitted along original optical path, The middle part of the convergence light 111 being emitted along original optical path is a central ray 141.Under this arrangement, converge light 111 by this One speculum 120 and the second speculum 130 divide for three parts, the first reflection light respectively reflected by the first speculum 120 121, the second reflection light 131 reflected by the second speculum 130, and not by the first speculum 120 and the second speculum 130 The central ray 141 of reflection, wherein the first speculum 120 and the first reflection light 121 and second of the second speculum 130 reflection The reflection direction of reflection light 131 is inconsistent so that the reflection light 131 of the first reflection light 121 and second projects object Two laser spots are formed after upper.The light of single light source is first created as producing the light of two laser spots by two single speculums Line, it is to be understood that under in such a configuration, just saved a light source；

- cylindrical mirror 140, it is arranged in the light path for the central ray 141 not reflected, central ray 141 is not passing through post During the mirror 140 of face, exist still in the form of it can produce the light of laser spots, after cylindrical mirror 140, scattered and formed by cylindrical mirror 140 One can produce the light of a laser rays on object.

Thus, the light of single light source is divided into by the spectral module 100 that there is the present invention to configure can produce two laser spots and one The form of laser rays, and because the source light of caused laser spots and laser rays comes from same light source, then caused laser spots and swash The frequency of light, light intensity etc. are basically identical, and inapplicable ask will not be caused due to being divided the change of form in practical operation Topic.

In one preferred embodiment, the first speculum 120 and the second speculum 130 and convergence light 111 are in 45 ° of angles, from And the light after the first speculum 120 and the reflection of the second speculum 130 is with convergence light 111 and in convergence light 111 The central ray 141 in portion is in 90 ° of angles, is just may be used on the photoelectric instrument for needing to produce mutually perpendicular laser electric wire, and First reflection light 121 and the second reflection light 131 will not be interacted, intersected, and avoid the generation of unnecessary hot spot.

In above-described embodiment, also alternatively the position of the first speculum 120 and the second speculum 130 is configured to：In Heart light 141 is set for axial symmetry, then the first reflection light 121 and the second reflection light 131 are right also relative to central ray 141 Claim so that the light extraction of two laser spots of spectral module 100 is mutually symmetrical with, the convenient photoelectric instrument with the spectral module 100 The position of light-emitting window is set.

Taken up space to save spectral module 100 or even photoelectric instrument, it is necessary to by the volume of spectral module 100 as far as possible Ground reduces, and therefore, can be configured to the distance of the first speculum 120 and the second speculum 130 to condenser lens 110 to be equal to cylinder The distance of the speculum 130 of the speculum of mirror 140 to the first 120 and second, also or above-mentioned first speculum 120 and second of diminution is anti- Penetrate in mirror 130 to the distance, the distance of the speculum 130 of the speculum of cylindrical mirror 140 to the first 120 and second of condenser lens 110 Any one or two.Those of skill in the art would appreciate that above-mentioned two will cause irreflexive situation to produce apart from too small, Excessive, can decay laser intensity, therefore, in actual use, should regard Operating condition adjustment.

In order to be further ensured that light intensity, the frequency of the first reflection light 121, the second reflection light 131 and central ray 141 Unanimously, the installation site of the first speculum 120 and the second speculum 130 can peel off 1/3rd of convergence light 111 respectively, make It is respectively the third light splitter for converging light 111 to obtain the first reflection light 121, the second reflection light 131 and central ray 141, So that laser spots caused by the first reflection light 121 and the second reflection light 131 is in the same size, central ray 141 passes through post The width of laser rays after face mirror 140 is consistent with the size of laser spots, to meet higher requirement.

It can also be appreciated that the first speculum 120 and the second speculum 130 are the light microscopic that is all-trans, it is anti-that first will be passed through The part for penetrating the convergence light 111 of the speculum 130 of mirror 120 and second is all reflected, and does not transmit, and clearly divides the first reflection Light 121, the second reflection light 131 and central ray 141.

Spectral module 100 in any of the above-described embodiment can be used into laser level, described above to produce The luminous intensity distribution form of the laser rays of two laser spots one, and due to being produced using only single light source, assembly cost and requirement of light regulation accordingly reduce, Optimize the overall structure of laser level.

It should be noted that embodiments of the invention have preferable implementation, and not the present invention is made any type of Limitation, any one skilled in the art change or are modified to possibly also with the technology contents of the disclosure above equivalent effective Embodiment, as long as without departing from the content of technical solution of the present invention, above example is made according to technical spirit of the invention Any modification or equivalent variations and modification, in the range of still falling within technical solution of the present invention.
