Abstract
The invention discloses a sighting telescope optical system for a gun, comprising an objective lens group, a transferring lens group and an eye lens group which are sequentially arranged from an object side to an image side. The transferring lens group is composed of a first positive lens group, a second positive lens group, a third positive lens group and a fourth positive lens group, wherein, the first positive lens group is arranged fixedly, the second positive lens group and the third positive lens group are arranged movably and the fourth positive lens group is arranged fixedly; and the first positive lens group, the second positive lens group, the third positive lens group and the fourth positive lens group are arranged sequentially from the object side to the image side. The sighting telescope optical system has simple structural design and processing, can obtain larger zoom ratio and relatively larger sighting telescope field of view, and reduce the field angle of the outgoing beam of a transferring system, thus correspondingly decreasing the lens aperture of an eye lens system at the rear end of a zoom system.
Description
Technical field
The present invention relates to sighting telescope optical system, particularly a kind of sighting telescope optical system for gun.
Background technology
At present, the dual-use gun sight that uses both at home and abroad, the optical system that it adopts; Also all being that objective lens, image rotation lenses group and eyepiece group are formed, is that two traditional positive lens groups move and realize becoming traditional classical mode doubly but its image rotation lenses group adopts, wherein moves near first set of lenses of thing side to be used to compensate the image planes drift; Moving realization near second set of lenses as side becomes doubly; This change times relay system can satisfy the optical property instructions for use of whole gun sight, and still, this traditional change times relay system also has a lot of defectives; Generally becoming multiple proportions can not be above 5 times; Otherwise will sacrifice the optical property of others, perhaps increase system complexity, realize bringing more manufacturability difficulties to system.
For a change this present situation; U.S. REDFIELD company has developed 5 times of gun sight series that become multiple proportions, adopts higher manufacturing process, and it becomes a times relay system and adopts three groups of three-flutes to become times mode; Just-just adopt-negative three groups of lens types establishment relay systems; When the location status of set of lenses when low power becomes high power, three set of lenses move by running orbit separately simultaneously, but adopt the complex structure of the gun sight of this relay system; The visual field optical property is not high, and the design that has restricted this relay system gun sight is promoted and made.
Summary of the invention
Technical problem to be solved by this invention is: a kind of sighting telescope optical system for gun is provided; Its structural design and processing is simple; Not only can obtain bigger change multiple proportions; Obtain relatively large gun sight visual field, and can reduce relay system outgoing beam subtended angle, thus the corresponding eyepiece system eyeglass bore that reduces the zooming system rear end.
For solving the problems of the technologies described above; Technical scheme of the present invention is: sighting telescope optical system for gun; To the picture side direction, comprise the objective lens, image rotation lenses group and the eyepiece group that are arranged in order setting along the thing side, said image rotation lenses group comprises first positive lens groups that fixedly installs; Mobile second positive lens groups that is provided with and the 3rd positive lens groups and the 4th positive lens groups that fixedly installs; To the picture side direction, said first positive lens groups, said second positive lens groups, said the 3rd positive lens groups and said the 4th positive lens groups are arranged in order along the thing side.
As a kind of optimized technical scheme, said first positive lens groups comprises the first plano-convex single-positive-lens of a slice convex surface towards said eyepiece group; Said second positive lens groups comprises a slice first gummed positive lens; Said the 3rd positive lens groups comprises a slice second gummed positive lens, and the convex surface of said first gummed positive lens and the said second gummed positive lens is relative; Said the 4th positive lens groups comprises the second plano-convex single-positive-lens of a slice convex surface towards said objective lens.
As a kind of optimized technical scheme, said objective lens is made up of a slice the 3rd gummed positive lens and a slice the 3rd plano-convex single-positive-lens, and said eyepiece group is made up of a slice the 4th gummed positive lens and a slice biconvex single-positive-lens.
After having adopted technique scheme, the invention has the beneficial effects as follows:
1. among the present invention, the image rotation lenses group comprises first positive lens groups that fixedly installs, mobile second positive lens groups that is provided with and the 3rd positive lens groups and the 4th positive lens groups that fixedly installs; To the picture side direction, said first positive lens groups, second positive lens groups, the 3rd positive lens groups and the 4th positive lens groups are arranged in order along the thing side.What therefore, the image rotation lenses group adopted is the portable times relay system that becomes of " just-just-just-just " four set of lenses and middle two set of lenses.The advantage of this optical system is not only to obtain bigger change multiple proportions: can have 5x-6x and become multiple proportions even hypermutation multiple proportions more, obtain relatively large gun sight visual field; And can reduce relay system outgoing beam subtended angle, thereby the corresponding eyepiece system eyeglass bore that reduces the zooming system rear end; In addition, because two set of lenses move in the middle of having only, this relay system only needs two and becomes times curved groove, and structural design and processing is simple.
2. among the present invention, first positive lens groups that constitutes the image rotation lenses group comprises the first plano-convex single-positive-lens of a slice convex surface towards said eyepiece group; Second positive lens groups comprises that a slice is used to compensate the first gummed positive lens of image planes drift; The 3rd positive lens groups comprises that a slice is used to become the second gummed positive lens of doubly effect; The 4th positive lens groups comprises the second plano-convex single-positive-lens of a slice convex surface towards said objective lens.Wherein, the convex surface of said first gummed positive lens and the said second gummed positive lens is relative.Therefore whole image rotation lenses group adopts four groups of symmetrical expression optical textures; Advantage is: symmetrical configuration, the light trend in relay system also is symmetrical, and objective lens and eyepiece group also are symmetrical about the image rotation lenses group; Light also is symmetrical in whole optical system; Thereby eliminate some aberrations, be particularly conducive to the structural design of small-bore gun aiming device, whole symmetry is both artistic and practical.
