Abstract
The utility model provides a total reflection cylindrical conical prism, comprising a cylindrical lens seat and a cylindrical lens body fixed on a top surface of the cylindrical lens seat. A top surface of the cylindrical lens body is provided with a reversed and hollow cone portion, forming a conical lens portion. The top of a conical surface of the conical lens portion is a plane so that the conical lens portion becomes an inverted hollow circular truncated cone. The total reflection cylindrical conical prism generates 360 DEG horizontal light beams through the conical lens portion on the top, and through chipping off the top end portion of the conical lens portion, the top of the conical lens portion becomes a plane so that the conical lens portion changes into the circular truncated cone. Since the conical lens portion and the cylindrical lens seat are coaxial, incident light to the top surface of the circular truncated cone emits along an axial direction and a light spot is generated. The bottom surface of the total reflection cylindrical conical prism is plated with an antireflection film, so luminous energy loss is very low and the antireflection film is beneficial for saving energy.
Description
Technical field
The utility model belongs to the laser optics applied technical field, is specifically related to a kind of total reflection cylinder cone prism.
Background technology
Existing post mirror is because its structure is mostly cylindricality, by glass, made, generally can only be for generation of point-like laser or linear laser, can not produce the laser rays of 360 degree, can produce the optical element of the laser rays of 360 degree, conical surface mirror (claiming again cone prism) commonly, generally there is metal to make, also useful optical plastic is made, cone prism as disclosed as Chinese patent 200920252021.7, it is made of plastics exactly, by being plated in the reflective membrane on its inside surface, to produce from the laser reflection of its end face direction incident 360 degree horizontal line light beams, the defect that this cone prism exists is one, it is made of plastics, the exposed easily dirty and damage of its surface in air of this optical element, produce dirty point, the disadvantage such as pit and cut, the optical element surface can continue to use after putting on the skin totally, and the plastic part surface is not easy wiped clean and easily scratch, need to renew part after scratch, workload is large and increased cost, two, conical surface plating reflective membrane, operation increases, and cost improves.
Summary of the invention
The purpose of utility model is to provide a kind of total reflection cylinder cone prism, it not only can be produced and decorate laser, and can produce the horizontal light beam of 360 degree.
For this reason, the total reflection cylinder cone prism that the utility model provides, comprise cylindrical microscope base and the cylindrical mirror body that is fixed on this cylindrical microscope base end face, the tapered portion that the end face of cylindrical mirror body is provided with an inversion and hollow forms a conical surface mirror section, thereby the conical surface top of this conical surface mirror section is a plane, makes this conical surface mirror section become an inverted hollow round table.
Above-mentioned cylindrical mirror body, conical surface mirror section are coaxial with cylindrical microscope base.
The bottom surface of above-mentioned cylindrical microscope base is coated with antireflecting film.
Above-mentioned cylindrical mirror body, conical surface mirror section and cylindrical microscope base are all to be made by glass.
The total reflection cylinder cone prism that the utility model provides, conical surface mirror section by its top produces 360 degree horizontal light beams, and the top ends by this conical surface mirror section of pruning makes it become a plane to make conical surface mirror section be deformed into round platform, due to conical surface mirror, section is coaxial with cylindrical microscope base, thereby makes the light of the end face that impinges perpendicularly on this round platform export vertically, produces luminous point, and this cylindrical microscope base bottom surface coated with antireflection film, therefore, light loss is very little, is beneficial to energy-conservation.
Below with reference to accompanying drawing, the utility model is described in further details.
The accompanying drawing explanation
Fig. 1 is total reflection cylinder cone prism schematic perspective view.
Fig. 2 is total reflection cylinder cone prism diagrammatic cross-section.
In figure: 1, cylindrical microscope base; 2, cylindrical mirror body; 3, conical surface mirror section; 4, conical surface top.
Embodiment
As shown in Figure 1, 2, the total reflection cylinder cone prism that the present embodiment provides, comprise cylindrical microscope base 1 and the cylindrical mirror body 2 that is fixed on this cylindrical microscope base 1 end face, the tapered portion that the end face of cylindrical mirror body 2 is provided with an inversion and hollow forms a conical surface mirror section 3, thereby the conical surface top 4 of this conical surface mirror section 3 is a plane, makes this conical surface mirror section 3 become an inverted hollow round table.And be not difficult to find out, cylindrical mirror body 2, conical surface mirror section 3 coaxially arrange with cylindrical microscope base 1, so, produce 360 degree horizontal light beams by conical surface mirror section 3, and the top ends by this conical surface mirror section 3 of pruning makes it become a plane to make conical surface mirror section 3 be deformed into round platform, because conical surface mirror section 3 is coaxial with cylindrical microscope base 1, thereby make the light of the end face that impinges perpendicularly on this round platform export vertically, produce luminous point, and this cylindrical microscope base 1 bottom surface coated with antireflection film, therefore, light loss is very little, is beneficial to energy-conservation.Like this, just produce the 360 degree horizontal light beams that can show the circular light beam center of circle, there is a light beam and Line beam dual property.
The cylindrical mirror body 2 related in the present embodiment, conical surface mirror section 3 are all to be made by glass with cylindrical microscope base 1.
In the course of the work, incident ray is when total reflection cylinder cone prism reflecting surface for the total reflection cylinder cone prism that the present embodiment provides, and light all reflection does not have refracted ray to occur.
More than exemplifying is only to illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, within the every and same or analogous design of the utility model all belongs to protection domain of the present utility model.
