Description

The light splitting bundle device of laser plumbing instrument

Technical field

The utility model is related to a kind of laser plumbing instrument, more particularly to a kind of light splitting bundle device of laser plumbing instrument.

Background technology

Laser plumbing instrument of the prior art be with laser as light source, in one or more directions produce laser rays or Laser spots, are widely used in the fields such as instrument of surveying and mapping, and generally, can launch 3 laser plumbing instrument of light beam needs to match somebody with somebody For a lasing light emitter and with three prisms or three LASER Light Sources of different directions of reflecting surface, although so realizing three Individual laser projection point, but because the reflecting surface of light source and light source is more, easily there is veiling glare, influence the bright of laser projection point Degree, can also substantially reduce the identification of laser plumbing instrument.

Utility model content

In order to solve the above technical problems, the purpose of this utility model is to provide a kind of simple structure and identification laser high The light splitting bundle device of cultellation instrument.

The light splitting bundle device of the laser plumbing instrument that the utility model is provided, including laser and the projection in the laser The light splitting bundle device that light direction is provided with, the light splitting bundle device is Amici prism, and the Amici prism is provided with an incidence Face and a corresponding exit facet, the plane of incidence are transmission plane, and the both sides of the plane of incidence are symmetrically distributed with two reflectings surface, Angle between two reflectings surface is 90 °.

Further, the light splitting bundle device is the isosceles trapezoid prism that a pair of base angles are 45 °, the isosceles trapezoid prism Upper bottom surface be the plane of incidence, the plane of incidence is the first transmission plane, and the bottom surface of the isosceles trapezoid prism is exit facet, described Exit facet is the second transmission plane.

Further, two inclined-planes of the isosceles trapezoid prism are coated with reflectance coating.

Further, also including the bluff piece being glued on the isosceles trapezoid prism bottom surface, the area of the bluff piece More than the area of the isosceles trapezoid prism bottom surface.

Further, the reflected beams that the incident beam that the laser sends is sent by the reflecting surface with by institute Angle formed by stating the outgoing beam that exit facet sends is 90 °.

Further, the reflected beams that the incident beam that the laser sends is sent by the reflecting surface with by institute The incident beam for stating the plane of incidence is vertical.

Further, it is coated with anti-reflection film on the transmission plane.

By such scheme, the utility model at least has advantages below：The laser plumbing instrument that the utility model is provided Laser is divided into three light beams by light splitting bundle device by light splitting bundle device, and simple structure reduces the volume of cultellation instrument, and distinguishes Knowledge and magnanimity are high.

Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below Describe in detail bright as after.

Brief description of the drawings

Fig. 1 is the structural representation of the light splitting bundle device of the laser plumbing instrument that the utility model is provided；

Fig. 2 is the structural representation of the Amici prism in the light splitting bundle device of the laser plumbing instrument that the utility model is provided.

Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is used to illustrate the utility model, but is not limited to scope of the present utility model.

Referring to Fig. 1 and Fig. 2, including laser 1 and the light splitting bundle device that is provided with the projection light direction of laser 1, point Beam device is Amici prism 2, and Amici prism is provided with a plane of incidence 3 and a corresponding exit facet 4, and the plane of incidence 3 is Face is penetrated, the both sides of the plane of incidence 3 are symmetrically distributed with two reflectings surface 5, and the angle between two reflectings surface 5 is 90 °.

The principle of the light splitting bundle device of the laser plumbing instrument that the utility model is provided is as follows：

In the market most are laser levels, extensive with range of application, and laser plumbing instrument is also gradually Received by market, on the projecting direction of laser 1 plus an Amici prism 2, two reflectings surface 5 are symmetrical and each other Angle is 90 °, laser 1 produce incident beam L1 through on Amici prism 2 two reflectings surface 5 reflection be divided into symmetrically and The reflected beams L2 and L3 vertical with incident beam, transmission is divided into outgoing beam L4, and the three-beam on three directions is divided into altogether, It is respectively L2, L3, L4, L2, L3, L4 can generate laser spots, the divided beams apparatus structure letter of the laser plumbing instrument of this structure Single, identification is high.

In order to meet two reflectings surface 5 on Amici prism 2 it is symmetrical the characteristics of, light splitting bundle device is for a pair of base angles 45 ° of isosceles trapezoid prism, the upper bottom surface of isosceles trapezoid prism is the plane of incidence 3, and the plane of incidence 3 is the first transmission plane, isosceles trapezoid The bottom surface of prism is exit facet 4, and exit facet is the second transmission plane；So, two inclined-planes of isosceles trapezoid prism can be as Two symmetrical reflectings surface 5 carry out reflex, and also ensure incident beam L1 and the reflected beams L2 and incident beam L1 and the reflected beams L3 each other formed angle equal to 90 °.

In order to increase by two reflected intensitys of reflecting surface 5, two inclined-planes of isosceles trapezoid prism are coated with reflectance coating.

In order to carry out appropriate protection, the also bluff piece including being glued on isosceles trapezoid prism bottom surface to Amici prism 2 6, the area of the area more than isosceles trapezoid prism bottom surface of bluff piece 6.

In order to ensure that the adjacent beams that laser plumbing instrument sends in three directions are mutually perpendicular to, what laser 1 sent enters Irradiating light beam L1 sends the reflected beams L2 and L3, L2 and L3 with the outgoing beam L4 institutes sent through exit facet 4 by two reflectings surface 5 Into angle be 90 °, L2 and L3 is vertical with the incident beam L1 by the plane of incidence 3.

In order to increase the transmittance of the plane of incidence 3 on Amici prism 2, anti-reflection film is coated with transmission plane.

The above is only preferred embodiment of the present utility model, be not limited to the utility model, it is noted that for For those skilled in the art, on the premise of the utility model know-why is not departed from, if can also make Dry to improve and modification, these are improved and modification also should be regarded as protection domain of the present utility model.
