Abstract
The utility model belongs to the field of optical, mechanical and electronic integration, and relates to a sighting telescope for a gun, in particular to an observing and sighting telescope capable of being used for a gun in daytime and at night. When the observing and sighting telescope is used at night, light arrives at an ocular lens 8 through an objective lens 1, an image intensifier 9 and a beam splitter 7, a reticule lens 3 is illuminated by a reticule lighting source 10, and a bright cross datum line is formed on the ocular lens 8. When the observing and sighting telescope is used in the daytime, a rotating reflector 2 blocks the image intensifier 9, the light enters the telescope from the objective lens 1 and similarly arrives at the ocular lens 8 through the rotating reflector 2, the reticule lens 3, a fixed reflector 4, a relay lens 5, a fixed reflector 6 and the beam splitter 7, and reticules on the reticule lens 3 similarly form a cross datum line on the ocular lens 8. The relay lens 5 is adjusted so that white light and dim light paths form images in a confocal manner, and the two cross datum lines in different colors are formed by sharing the reticule lens 3 so that an observing and sighting system capable of being used in the daytime and at night is realized.
Description
Technical field
Patent art belongs to the optical, mechanical and electronic integration field, relates to a kind of riflescope, particularly about a kind of riflescope of unification round the clock with microcosmic night vision function.
Technical background
Observe gun sight and be mainly used in military affairs, public security, arms department, can be used for observation, seizure and run-home.Now; Whether the fire accuracy of firearms and sighting equipment advanced closely related, and domestic up to now optical sight is the gun sight or lll sight in daytime of simple function, they can only be by day or night a single state use down; When day alternates with night; Can only change gun sight, this just needs to be equipped with two gun sights, brings great inconvenience to use; Next changes gun sight needs the regular hour, does not possess the ability of real-time response, and when changing gun sight, reset error can occur, influences pointing accuracy.So press for and have the gun sight of unifying function round the clock; Promptly requiring gun sight to have lll night vision simultaneously sees the system that takes aim at and sees the system that takes aim at daytime; The use that gun sight is observed in unification round the clock can further improve individual soldier's warfighting capabilities, makes individual soldier's weapon of fighting possess round-the-clock precision strike capability.At present; In the world as: most countries such as France, Japan, Russia, Britain, Holland can only be produced the observation gun sight of simple function; Some possess research and development and produce the country of gun sight image intensifier round the clock and can develop the observation gun sight of unification round the clock to have only the U.S., Israel etc.; Gun sight image intensifier market is all captured by it round the clock in the world, and third world countries' technical application is blocked.In China, this product or blank out.Patent art is that my company is on the patented technology of having declared " a kind of lll night vision riflescope " (application number is 201010256300.8) and " a kind of dual-purpose round the clock shooting pointing device " (application number is 201010257332.X) basis; Adjust the technology of light path confocal imaging round the clock through one; Technology and the technology of lll sight of gun sight are synthesized in one with daytime; Realize the observation aiming of unification round the clock, market potential is huge, has bright development prospect.
Summary of the invention
The purpose of patent art provides a kind of taking into account and sees the system that takes aim at daytime and see the system that takes aim at lll night vision, the observation gun sight of unifying round the clock.Referring to accompanying drawing 1 is the patent art optical system diagram, comprises object lens 1, rotates reflective mirror 2, graduation mirror 3, fixed counter-mirror 4, relay lens 5, fixed counter-mirror 6, spectroscope 7, eyepiece 8, image intensifier 9, graduation lighting source 10.Object lens 1, image intensifier 9, eyepiece 8 are on the same axis, under night low-light environment, rotate reflective mirror 2 and upwards rotate; Light is through object lens 1, image intensifier 9, spectroscope 7, arrival eyepiece 8; And graduation mirror 3 is through 10 irradiations of graduation lighting source, after silver-plated cross hairs is illuminated on it, through stationary mirror 4, relay lens 5, stationary mirror 6, graduation mirror 7; Form the cross datum line at eyepiece 8, be used for the aiming of target.When light is strong by day; Rotate reflective mirror 2 retainings in image intensifier 9 fronts, image intensifier 9 and graduation lighting source 10 are not worked, and light is got into by object lens 1; Rotate reflective mirror 2 turnover light paths; Through graduation mirror 3, fixed counter-mirror 4, relay lens 5, fixed counter-mirror 6, spectroscope 7, arrive eyepiece 8 equally, the cross hairs on the graduation mirror also forms the cross datum line at eyepiece 8 simultaneously.Said graduation mirror 3 is a slice plano-convex positive lens, and silver-plated cross hairs is arranged on its plane, and daytime is when using, because cross hairs is light tight, what in the visual field, see is black cross datum line; Adopt graduation lighting source 10 from the side to illuminate cross hairs when using night, and what in the visual field, see is bright cross datum line.Two kinds of patterns are switched down round the clock, and two kinds of different colours cross datum line positions that graduation mirror 3 forms are identical.
Patent art is through daytime and low-light double light path confocal imaging; And shared graduation mirror 3 forms two kinds of cross datum lines that the different colours position is identical; Realized the observation aiming of unification round the clock; And rotate speculum 2 and can switch at any time and see the system that takes aim at daytime and see the system that takes aim at lll night vision, simple operation, precision height.
Referring to accompanying drawing 2 are patent art relay lens 5 optical system diagrams, and said relay lens 5 adopts the double gauss structural shape of symmetry, and wherein I is object lens 1 image planes, and F is eyepiece 8 front focal planes, and d be that the adjustable distance between the G2 is organized in the preceding group of G1 and the back of symmetry.Relay lens 5 has the effect of inverted image and adjustment light path in daytime and low-light light path confocal imaging; Object lens 1 image planes I also is the front focal plane of preceding group of G1; The picture of object lens 1 is a directional light through the light of outgoing behind the G1; G1 outgoing directional light is the incident directional light of G2, through the size of regulating d make through the light of G2 outgoing just focal imaging at eyepiece 8 front focal plane F, because the picture of low-light light path object lens 1 also becomes at eyepiece 8 front focal plane F; Daytime light path and low-light light path confocal imaging, realized the purpose that it is unified round the clock.Because the cooperation of object lens 1 and eyepiece 8 is adopted is Kepler's pattern of looking in the distance; Imaging is stood upside down; The low-light light path is through image intensifier 9 inverted image once more, and daytime light path through relay lens 5 once more inverted image make final to be upright in eyepiece 8 imagings, to be suitable for people's emmetropia and to observe.
Referring to accompanying drawing 2 are patent art relay lens optical system diagrams; Before said group G 1 have by the tactic first lens L1 of object lens 1 one sides, second pass through through L2, the 3rd lens L3, wherein the second lens L2 and the 3rd lens L3 are the gummed assembly; The first lens L1 is concavo-convex negative eyeglass; The second lens L2 is the positive eyeglass of convex-concave, and the 3rd lens L3 is the positive eyeglass of biconvex, and group G2 is identical with preceding group of G1 eyeglass symmetry in the back.Preceding group G1 comprises that the focal length of three optical lenses and the radius of curvature of refractive index and five faces meet the following conditions respectively:
