Definitions

  • the invention relates to a telescopic sight according to the preamble of claim 1.
  • Rifle scopes are used in hunting and in the military for targeting targets at great distances by means of weapons.
  • the lens arrangement has at least one objective and one eyepiece.
  • the objective is a collecting optical system for real optical imaging of the target object and the eyepiece is a lens system through which one eye looks into the lens arrangement.
  • An intermediate image designed by the objective in an objective-side image plane is magnified in an eyepiece-side image plane.
  • the magnification however, the viewing angle is very limited and objects at a shorter distance can be poorly sighted or viewed.
  • the prior art provides a variable magnification, the so-called zoom.
  • the targeted object in the lens-side image plane is reversed and upside down and must therefore be corrected.
  • a reversal system is used within the riflescope.
  • This allows an axial independent or defined displacement of two optical elements.
  • the optical elements include lenses, Kittlinsen and Reticle.
  • an intermediate image generated in the lens-side image plane is erected and enlarged in the eyepiece-side image plane where it is viewed.
  • each individual lens produces different aberrations in the optical imaging of the object into a virtual or real intermediate image, including spherical aberration, defocus, coma, field curvature, distortion, longitudinal and transverse color aberrations in various orders.
  • the lenses are combined and arranged in the objective of a riflescope in such a way that the errors over the beam path from the object to the image compensate each other as well as possible.
  • flint and crown glass lattices are used to correct the chromatic aberrations.
  • optical means Despite the use of optical means remains in the first image plane always a certain amount of aberrations, especially in combinatorial binoculars or riflescopes, especially at a more than fourfold magnification, in the eyepiece image plane at a high magnification are increasingly visible. Transverse aberrations are magnified linearly and longitudinal errors are magnified quadratically.
  • the prior art provides to reduce the image errors by clever design of the lens system so that a consistently good image quality over the entire magnification range is guaranteed.
  • a combatzoomiges rifle scope is for example in EP 1 746 451 B1 described.
  • This describes a telescopic sight, with a central tube, which is arranged between a lens and an eyepiece.
  • the center tube contains a reversing system, in which an adjustable magnification optics is integrated.
  • This consists of two relatively movable optical elements.
  • the reversing system is arranged between an objective-side image plane and an eyepiece-side image plane. By moving the optical elements, an intermediate image designed by the objective in the lens-side image plane is enlarged and erected with a variable magnification in the eyepiece-side image plane.
  • the maximum magnification is at least fourfold.
  • an optical beam deflection device is integrated into the reversing system.
  • This consists of an additional lens arrangement which is arranged on the eyepiece facing side of the reversing system and has a negative refractive power between -20 dpt (diopters) and - 40 dpt. This expands the magnification range. This ensures a subjective field of view of the telescopic sight of at least 22 °, at least for light with a wavelength of about 550 nm at all magnifications.
  • the reversing system on the object side spaced from the lens-side image plane has a field lens, by means of which a beam coming from the lens of an object point lying on the field of view can be guided through the narrow channel of the reversing system.
  • This field lens also has the task of moving the magnification range of the riflescope and is not used primarily for image aberration correction.
  • the object of the invention is therefore to reduce the aberrations over the entire magnification range, especially in the edge region and even at low magnifications, the solution should cause a low mechanical complexity and low cost.
  • the riflescope should remain easy and comfortable to handle and have a long service life.
  • a telescopic sight with a arranged between a lens and an eyepiece reversing system having an objective-side field lens and eyepiece at least two relatively displaceable optical elements, with a lying between the lens and the field lens and the field lens spaced lens side image plane and between the eyepiece and the eyepiece-side image plane underlying the inversion system, wherein an intermediate image designed by the lens in the lens-side image plane is displayed in the eyepiece image plane by the displacement of the optical elements and with at least four times the maximum magnification
  • the invention provides that between the lens side image plane and the field lens a correction field lens is arranged.
  • Such a correction field lens is not movable, which increases the complexity of the scope only slightly.
  • image errors are less pronounced in the inverse system. This considerably increases the image quality.
  • the correction field lens is insensitive to vibrations as well as thermal changes that result from the use under different operating conditions. This results in a long life of the riflescope.
  • the actuating forces for the movable optical elements are not increased, which would require a more stable and thus heavier design.
  • the few additional components required increase the weight of the riflescope only insignificantly.
  • the scope remains light, comfortable and easy to handle.
  • the particular advantages of the correction lens at the position according to the invention result from the correction of various aberrations that are less pronounced on the eyepiece-side image plane occur. Particularly advantageous is the position between the lens-side image plane and the field lens. Through this, the image aberration changes depending on the position of the movable optical elements and thus the magnification. It is now possible to design the image aberration correction over the entire zoom range in such a way that a brilliant, sharp and well-illuminated image is displayed on the eyepiece-side image plane. A third movable optical element in the inverse system is not required.
  • a beam path is influenced in such a way that inter alia the spherical aberration and the coma are reduced at all magnifications, but in particular at the small magnification, in the eyepiece-side image plane, but also astigmatism and field curvature are reduced.
  • the correction field lens serves to correct the aberrations already coming out of the objective, but also to compensate for the aberrations arising in the reversal system, so that the best possible image is produced in the eyepiece-side image plane.
  • the correction field lens is arranged between the lens-side image plane and the field lens, since this allows the errors from the lens to be corrected.
  • the following table shows the influence of the inventive correction field lens on 3rd order aberrations, according to an optical design program according to MIL-HDBK-141 (Military Standardization Handbook: Optical Design): Image defect intensity from optical design program according to MIL-HDBK-141 WITHOUT CORRECTION FIELD LENS WITH CORRECTION FIELD LENS Picture Error Type Small magnification Medium magnification Big magnification Small magnification Medium magnification Big magnification Spherical aberration 0.821086 0.150681 0.235905 0.448830 0.106225 0.187797 coma -0.199421 -0.100022 0.100028 -0.051632 -0.100011 0.100030 Tangential astigmatism 0.307891 -0.011196 0.067351 0.066316 -0.051988 0.033315 Sagittal astaxism 0.239279 0.023984 0.037844 0.136409 0.004444 0.023182 Curvature of field 0.204973 0.0415
  • the correction field lens is arranged on the side of the lens-side image plane facing away from the objective.
  • the lens can be designed with a plan side facing the lens and can be arranged directly at the lens-side image plane. This allows cementing with a reticle or reticle. As a result, the transmission is not significantly reduced, and the otherwise high sensitivity of the two mutually facing glass surfaces of reticle and correction field lens against the visibility of scratches is significantly reduced in the cemented surface.
  • the correction field lens is collecting or scattering. This may be convex, concave or flat. Particularly advantageous is a spherical and / or planar surface, since such a correction field lens costs significantly less than aspherical lenses.
  • a development provides that a reticle is arranged on the correction field lens, preferably in the lens-side image plane.
  • the correction field lens is cemented to the reticle. This reduces the complexity of the optical arrangement and the necessary fastening means. Thermal influences and vibrations have no increased effect on the optical arrangement. Thus, the weight of the riflescope remains low and it results in a good comfortable handling. In principle, however, it would also be possible to arrange the reticle in the eyepiece image plane, as it is found especially in the American market.
  • a beam splitter is arranged between the eyepiece-side image plane and the eyepiece. This can be used to reflect another target in the riflescope.
  • a variant of the invention provides that the objective consists of an objective lens and an objective achromat arranged between the objective lens and the objective-side image plane.
  • a further lens achromat can be provided, which is arranged on the same side of the objective lens or the opposite side of this.
  • the eyepiece consists of an eyepiece lens and an eyepiece achromat arranged between the eyepiece lens and the eyepiece-side image plane.
  • the second optical element is arranged closer to the eyepiece than the first optical element, and that in the inversion system a beam deflecting device with negative refractive power is arranged between the second optical element and the eyepiece-side image plane.
  • the magnification range is widened. This is particularly advantageous in combinatorial processes.
  • the correction field lens is particularly advantageous for improving the image quality if the maximum magnification of the intermediate image on the eyepiece-side image plane is at least fivefold, but preferably at least sixfold and particularly preferably at least eightfold. Especially with large magnification ranges, a sharp and brilliant image over the entire image area, in particular up to the edge of the image, is thus achieved even at the low magnifications.

Without such an adjustment, the point of impact could deviate from the target because of the trajectory of the projectile, which is affected by, among other things, gravity and wind energy.
  • the reversing system 30 has an objective-side field lens 50 and eyepiece-side two relatively movable optical elements 31, 32, wherein the second optical element 32 is disposed closer to the eyepiece 20 than the first optical element 31.
