But, the laser module with beam-splitting structure of above-mentioned prior art, it designs complicated, and the parameters relationship between this wave mirror 2a, this spectroscope 3a and this catoptron 4a is wayward.In addition, the energy of this laser beam 6a makes that through the too much loss of part this laser beam 6a brightness is not good.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of laser module with beam-splitting structure, its design simplification, part reduces, assembling easily, and can reduce the luminous energy loss, dwindle this laser module volume, and the parameters relationship between each part is controlled easily, and then the reduction manufacturing cost, improve the quality of products.

In order to realize above-mentioned purpose, the utility model provides a kind of laser module with beam-splitting structure, comprising: a module base; One spectroscope, it is arranged at this module base; One light emitting module, it is arranged at this module base below, and this light emitting module is an angle corresponding to this spectroscope, and the laser beam that this light emitting module sent directly is projeced into this spectroscope; And a wave mirror, it is arranged at this module base, and this wave mirror is an angle corresponding to this spectroscope correspondence.

The utlity model has following useful effect: the utility model is mainly borrowed the position that changes light emitting module, to omit the use of catoptron, make its design simplification, part reduces, and assembling is easy, and can reduce the luminous energy loss, dwindle this laser module volume, and because of part reduces the parameters relationship between each part is controlled easily, and then reduced manufacturing cost, improve the quality of products.

For enabling further to understand feature of the present utility model and technology contents, consult following relevant for detailed description of the present utility model and accompanying drawing, yet appended graphic only for reference with the explanation usefulness, be not to be used for the utility model is limited.
