Abstract
The invention discloses a kind of reflex sights, including：Light source and imaging lens；Further include a reflecting prism, which includes a plane of incidence, an exit facet and at least one reflecting surface；The irradiation light that the light source is sent out enters the reflecting prism through the plane of incidence, and is projected from the exit facet under the reflex of the reflecting surface；The imaging lens are located in the light path of the irradiation light projected through the exit facet.Compared with prior art, the present invention irradiates reflecting prism by light source, is imaged by reflecting prism multiple reflection inside, then by imaging lens, forms traditional reflex sight.The imaging system has broken the imaging pattern of conventional reflective gun sight, and the propagation distance of light is increased by reflecting prism image rotation, solves conventional reflective gun sight since focal length is too short, is not easy to aim at problem of parallax experienced caused by focusing.The volume that gun sight can be greatly reduced from structure simultaneously, is convenient for carrying and assembles.
Description
Technical field
Patent of the present invention belongs to laser optics applied technical field, and in particular to a kind of reflex sight.
Background technology
Existing reflex sight（Red point takes aim at tool in also known as）, referring to 203132428 U of CN, light path composition is main
It is made of light source and enocscope, wherein light source uses laser light source.Between light source setting angle and light source and refracting telescope away from
Very accurate from requiring, processing and assembly are difficult.
Conventional reflective gun sight will accomplish that smaller just needs to shorten the focal length of enocscope, that is, further light source and refraction
The distance between mirror, short focus may result in aberration phenomenon, that is, aim at parallax.
Invention content
Patent of the present invention provides a kind of coke the technical problem to be solved is that in view of the deficiency of the prior art
Distance, the reflex sight for being easy to focusing.
In order to solve the above technical problems, patent of the present invention the technical solution adopted is that：
A kind of reflex sight, including：Light source and imaging lens；It is characterized in that：Further include a reflecting prism, the reflection rib
Mirror includes a plane of incidence, an exit facet and at least one reflecting surface；The irradiation light that the light source is sent out is through the plane of incidence
Into the reflecting prism, and projected from the exit facet under the reflex of the reflecting surface；The imaging lens are located at warp
In the light path for the irradiation light that the exit facet projects.
Aiming mark is provided in the prism, it is anti-for the first time through plane of incidence progress that the aiming mark is located at irradiation light
On the reflecting surface penetrated.The face is the maximum face of light-inletting quantity.
The imaging lens are refracting telescope.
The refracting telescope is plane mirror.
The reflecting prism has 4 reflectings surface.
The light source is LED light tube or laser light source.
Compared with prior art, the advantageous effect of patent of the present invention is：
Reflecting prism is irradiated by light source, the faces A of reflecting prism are coated with aiming mark, aim at mark under the conditions of optical illumination, lead to
Reflecting prism multiple reflection inside is crossed, reflects mark picture, then be imaged by imaging lens, forms traditional reflective take aim at
Quasi- mirror.The imaging system has broken the imaging pattern of conventional reflective gun sight, and light is increased by reflecting prism image rotation
Propagation distance solves conventional reflective gun sight since focal length is too short, is not easy to aim at problem of parallax experienced caused by focusing.It simultaneously can
The volume that gun sight is greatly reduced from structure is convenient for carrying and assembles.

Fig. 2 is the index path of patent reflecting prism of the present invention.
Wherein：1. reflecting prism；11. the plane of incidence；12. exit facet；13. the first reflecting surface；14. the second reflecting surface；15.
Third reflecting surface；16. the 4th reflecting surface；2. imaging lens；3. light source；4. human eye.
Specific implementation mode
Below in conjunction with the accompanying drawings, it elaborates to patent of the present invention：
As shown in Figure 1, patent reflex sight of the present invention, including reflecting prism 1, imaging lens 2 and light source 3.Wherein light source 3
For sending out irradiation light, LED light source or laser light source can be used.Image glass can be used for being imaged in imaging lens, refracting telescope,
The semi-transparent mirror or other of partly returning can realize the plane mirror of imaging function.
As shown in Fig. 2, reflecting prism 1 includes 11, exit facets 12 of a plane of incidence and at least one reflecting surface.Light source
3 irradiation lights sent out enter reflecting prism 1 through the plane of incidence 11, and are projected from exit facet 12 under the reflex of reflecting surface.At
It is located at as mirror 2 in the light path of the irradiation light projected through exit facet 12.
It is machined with figure on the surface of light source 1, figure is that point, circle, circle and point, small cross etc. can be used for aiming at mark
Pattern.Figure is projected by light source 3, is entered in prism 1 after the refraction of prism 1, and the multiple reflections in prism 1, later
Figure is reflected to imaging lens 2 through prism 1, then imaged mirror 2 is reflected and reflected away again.The setting in reflecting prism 1
There is aiming to identify, aiming mark carries out the faces A on the reflecting surface of first reflection namely in Fig. 1 positioned at irradiation light through the plane of incidence.
But change sighted direction can install additional after the plane mirror of specially treated can refraction image seen in the another side of glass
Examine imaging.
In the present embodiment, reflecting prism 1 has 4 reflectings surface, including the first reflecting surface 13, the second reflecting surface 14, the
Three reflectings surface 15 and the 4th reflecting surface 16.It aims at mark to be located on the first reflecting surface 13, the irradiation light that light source 3 is sent out is passed through successively
It is projected from exit facet 12 after first reflecting surface 13, the second reflecting surface 14, third reflecting surface 15 and the 4th reflecting surface 16.
The reflecting surface of reflecting prism 1 can also be more；The angle of reflecting surface is related with the angle of emergent ray, to meet light
The principle of reflection of line.
Imaging lens 2 are semi-transparent semi-reflecting refracting telescope.Refracting telescope can also use the flat glass of special coating film treatment, such as exist
Plane mirror surface plates two or more different membrane systems.
Gun sight of the present invention, will be aimed in the form of prism internal reflection mark be imaged onto external image glass realize observation and
The sighting system of aiming.Light source 3 irradiates reflecting prism 1, and light after the 1 single or multiple reflections in inside of reflecting prism by reflecting
Go out, be then imaged again by imaging lens 2, is observed for human eye 4.
