Abstract
The invention provides a laser and visible light light-splitting erecting prism group comprising a rigging prism and a composite prism, wherein the composite prism is glued by at least two prisms and forms a visible light path together with the rigging prism, the glue surface of the composite prism is provided with a spectro-film, a laser is arranged at the position opposite to the reflection surface of the composite prism, and a laser axis and the composite prism visible light path form mirror images relative to the glue surface of the composite prism. Therefore, the prism group has both image erecting function and light-splitting function, and can respectively extract visible light information and laser information and respectively process all the information; and optical products, such as telescopes, cameras, and the like, which apply the prism group with image erecting function and light-splitting function, can utilize visible light to do observation or camera shooting, utilize laser to measure distances, and the like, thereby expanding the function of the products and being more convenient for users to use.
Description
Technical field
The present invention relates to a kind of prism group, especially a kind of erecting prism group that can allow laser and visible light carry out beam split belongs to the optical instrument technical field.
Background technology
Be applied in erecting prism in visualization or the image pickup optical system at present usually by roof prism, the isosceles prism is formed.The effect that it plays in light path is: after the imaging of the place ahead optical system such as object lens is turned around, pass to the optical system such as the object lens at rear, therefore only possess the function of erect image.In the practical application of erecting prism group, people wish that also the erecting prism group is when possessing the erect image function, also possesses the beam split function, make optical instrument such as the optical articles such as telescope, video camera of using this prism group with erect image function and beam split function, can extract respectively visible light information and laser intelligence and handle respectively after, utilize visible light to observe or make a video recording, utilize laser ranging.But existing erecting prism group does not possess such function, thereby gives product such as telescope, the video camera etc. that use the erecting prism group, brings function singleness, uses problems such as inconvenience.Therefore, be necessary prior art is improved.
Summary of the invention
Have only the erect image function and then bring insufficiency for optical articles such as its telescope of use or video camera for solving existing erecting prism group, use problems such as inconvenience, the invention provides a kind of laser and visible light light-splitting erecting prism group, to extract visible light information and laser intelligence respectively.
The present invention finishes by following technical proposal: a kind of laser and visible light light-splitting erecting prism group, comprise roof prism, it is characterized in that also comprising the composite prism that composes by two prisms at least that together constitutes the visible light light path with roof prism, and on the cemented surface of composite prism, establish spectro-film, and laser instrument being set with composite prism reflecting surface opposite position, laser axis and composite prism visible light optical axis become mirror image with respect to the cemented surface between composite prism.Thereby make visible light light path and the laser optical path cemented surface between composite prism become mirror image, to finish the beam split of visible light and laser.
Described composite prism reflecting surface and exit facet constitute 50～65 ° angle.
Spectro-film on the described composite prism cemented surface and composite prism exit facet constitute 25～32.5 ° angle.
Described spectro-film adopts laser instrument peak wavelength reflectivity greater than 98%, to visible light transmissivity greater than 85% conventional spectro-film.
Described laser instrument is conventional generating laser, perhaps is laser pickoff.
The present invention compared with prior art has following advantage and effect: adopt such scheme, can make the prism group when possessing the erect image function, also possesses the beam split function, so that can extract visible light information and laser intelligence respectively, and respectively each information is handled, thereby make optical instrument such as the optical articles such as telescope, video camera of using this prism group with erect image function and beam split function, can utilize visible light to observe or make a video recording, utilize laser to find range etc., expanded the function of these products, more user-friendly.
Description of drawings
Fig. 1 is the present invention's structural representation.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Laser provided by the invention and visible light light-splitting erecting prism group, comprise roof prism 1, also comprise the composite prism that composes by two prisms 2 and 5 that together constitutes visible light light path B with roof prism 1, and on cemented surface, establish spectro-film 4, and with composite prism in 2 reflecting surface opposite position generating laser 3 is set, the axis of generating laser 3 (light path) A and composite prism visible light optical axis B become mirror image with respect to the cemented surface between composite prism (being spectro-film 4).Wherein, the exit facet of the reflecting surface of the prism in the composite prism 2 and prism 5 constitutes 60 ° angle a; The spectro-film 4 on the cemented surface that composite prism is 2,5 and the exit facet of the prism 5 in the composite prism constitute 30 ° angle b; Spectro-film 4 adopts laser instrument peak wavelength reflectivity greater than 98%, to visible light transmissivity greater than 85% conventional spectro-film.
Principle of work of the present invention is as shown in Figure 1: the imaging beam of coming in from the left side is imaged on the order location 6 on right side through the erecting prism group that is made of roof prism 1, composite prism 2 and 5, thereby works in the visible light section.After the prism 2 of the light that generating laser 3 sends from composite prism incided spectro-film 4, the light of telling was launched to the left through prism 2, prism 1.
When 3 are laser pickoff, the laser beam of coming in from the left side, through prism 1, prism 2, spectro-film 4 arrives laser pickoff 3.
