Abstract
The utility model discloses a continuous times-changing ocular lens provided with a reticle, and a continuous times-changing optical observation system. The continuous times-changing ocular lens provided with the reticle comprises a fixation lens set, a compensation lens set, a times-changing lens set and the reticle. The fixation lens set at least comprises a fixation lens; the compensation lens set at least comprises a compensation lens; the times-changing lens set is arranged between the fixation lens set and the times-changing lens set; and at the same time, the reticle is disposed between the compensation lens set and the times-changing lens set and can move between the compensation lens set and the times-changing lens set so as to enable the reticle to always remain at the combination focal plane of the fixation lens set and the times-changing lens set.
Description
Technical field
The utility model relates to a kind of continuous zoom eyepiece and continuous zoom optics that is provided with graticule and looks around system.
Background technology
The continuous zoom optical system of existing graticule range finding, all that graticule is placed on the front focal plane or back focal plane that lens turn to zooming system, typical system is with lens, to turn to the sighting telescope system of the continuous zoom of zoom, and have to use for some, do not turn to Zoom lens group and use the eyepiece of continuous zoom to realize the heavy caliber of continuous zoom, the telescopic system of large multiplying power, as the bird appreciation mirror of continuous zoom, with the astronomical telescope of continuous zoom eyepiece, because image planes are virtual image faces and cannot place graticule and find range.
Summary of the invention
The utility model, for for the deficiencies in the prior art, provides a kind of when energy continuous zoom is observed, also can realize a kind of continuous zoom eyepiece and continuous zoom optics that is provided with graticule of the graticule range finding of target object is looked around to system.It specifically comprises as follows: a kind of continuous zoom eyepiece that is provided with graticule, and it comprises,
One fixed lens group, described fixed lens group at least comprises a fixed lens;
One offset lens group, described offset lens group at least comprises an offset lens;
One Zoom lens group, described Zoom lens is mounted between described fixed lens group and described Zoom lens group; Meanwhile,
One graticule, described graticule is between described offset lens group and described Zoom lens group, and described graticule can move between described offset lens group and described Zoom lens group, and described graticule is positioned on the combination focal plane of described fixed lens group and described Zoom lens group all the time.
On the basis of technique scheme, described graticule is connected with cam mechanism, and described cam mechanism is controlled described graticule and moved between described offset lens group and described Zoom lens group.
On the basis of technique scheme, described graticule is provided with one or more groups mil scale.
On the basis of technique scheme, described offset lens group connects offset lens cam, and described offset lens cam is controlled described offset lens group and moved.
The present invention also provides a kind of continuous zoom optics to look around system, and it comprises,
One objective lens, described objective lens is provided with at least one object lens;
The continuous zoom eyepiece that is provided with graticule described in one;
One prism group, described prism group described objective lens and described in be provided with between the continuous zoom eyepiece of graticule, meanwhile,
The described continuous zoom optics system of looking around has a plurality of multiplying powers, and described graticule is provided with many group mil scales, and described many group mil scales and described a plurality of multiplying power Corresponding matching.
Compared with prior art, tool has the following advantages in the present invention:
Between offset lens group and described Zoom lens group, graticule is set, and graticule can move between offset lens group and described Zoom lens group, graticule is positioned on the combination focal plane of described fixed lens group and described Zoom lens group all the time, realized when energy continuous zoom is observed, also can realize the graticule range finding to target object.
Accompanying drawing explanation
Fig. 1 is a kind of continuous zoom eyepiece schematic diagram that is provided with graticule of the utility model;
Fig. 2 is continuous zoom eyepiece the first view that the utility model is provided with graticule;
Fig. 3 is continuous zoom eyepiece the second view that the utility model is provided with graticule.
Embodiment
With reference to Fig. 1, a kind of continuous zoom eyepiece that is provided with graticule of this utility model, it comprises a fixed lens group 1, fixed lens group 1 at least comprises a fixed lens; One offset lens group 2, offset lens group 2 at least comprises an offset lens.Zoom lens group 3, Zoom lens group 4 is located between fixed lens group 1 and Zoom lens group 3; Between offset lens group 2 and Zoom lens group 4, be provided with graticule 5, graticule 5 is connected with cam mechanism (not shown), and cam mechanism is controlled graticule 5 and moved between offset lens group 2 and Zoom lens group 4.Graticule 5 is positioned on the combination focal plane of fixed lens group 2 and Zoom lens group 3 all the time.Graticule 5 is provided with one or more groups mil scale, for realizing the graticule range finding to target object.Offset lens group 2 also connects offset lens cam (not shown), and offset lens cam is controlled described offset lens group 2 and moved.Offset lens group 2 links together with Zoom lens group 3 by offset lens cam, and eyepiece image planes in the process that changes continuously focal length are not subjected to displacement all the time.
Please refer to Fig. 2 and Fig. 3, the state that it illustrates respectively continuous zoom eyepiece that the utility model is provided with graticule while adjusting.When adjusting eyepiece, offset lens group 2, Zoom lens group 3 and all corresponding movements of graticule 5, graticule 5 is positioned on the combination focal plane of fixed lens group 1 and Zoom lens group 3 all the time, by graticule 5, can be realized the graticule of target object is found range.
A kind of continuous zoom optics of the present utility model is looked around system, and the continuous zoom eyepiece that it has objective lens 6 and is provided with graticule, is provided with prism group 7 therebetween.The continuous zoom optics system of looking around has a plurality of multiplying powers, and graticule 5 is provided with many group mil scales, organizes mil scale and described a plurality of multiplying power Corresponding matching more.To realize the graticule range finding to target object under each different multiplying power.
