Sighting telescope for shooting based on Keplerian telescope and wave front aberration principle

Abstract

The present invention discloses a sighting telescope for shooting, which is based on a kepler telescope and wavefront aberration principle, which belongs to the optics technical field. The sighting telescope comprises an objective lens group, a positive image lens group, a reticule, a phase plate and an eyepiece group, wherein the objective lens group and the eyepiece group are confocal and form the kepler telescope; the reticule and the phase plate are arranged between the objective lens group and the eyepiece group; the reticule is arranged on the common focus of the objective lens group and the eyepiece group; the phase plate is arranged on the right side of the reticule to be confocal with the objective lens group and the eyepiece group so as to form the ocular circle conjugation of the kepler telescope. The positive image lens group is arranged between the objective lens group and the reticule. The sighting telescope achieves the basic aiming function; meanwhile the sighting telescope is capable of perfectly correcting various aberrations of the sighting telescope system of a shooter, so that the shooter is capable of obtaining eyesight exceeding normal eyesight range withoutextra auxiliary tools.

Description

technical field [0001] The invention relates to a device in the field of optical technology, in particular to a shooting scope based on the Kepler telescope and the principle of wavefront aberration. Background technique [0002] The vast majority of optical sights use the Kepler telescopic system, which consists of an objective lens group (composed of convex lenses), a erect lens group (composed of two convex lenses as the central lens), a reticle, and an eyepiece group (composed of convex lenses) made up of. The image formed by the objective lens group is an inverted image after the erect lens. Then it is transformed into a positive image in the human eye through the eyepiece. Using the Kepler telescopic system can see the details of objects more clearly, and increase the ability of long-distance human eyes to observe long-distance targets. And there is a real image in this telephoto system, so it is easy to set the reticle. [0003] However, the improvement direction ...

AI Technical Summary

Problems solved by technology

Its shortcoming is that the structure does not add a positive image lens group, and the final image is an inverted image, and it does not take into account the aberration of the shooter's human eye and the aberration of the sight system itself, so it cannot be better. Guarantee the coordination accuracy between the shooter's eyes and the scope
