[0078]

[0079] In the table, surface numbers R1 to R25 are arranged in sequence from the object side to the image side.

[0080] The working principle of the sight's optical system includes the following: when the sight changes from high to low magnification, the first zoom lens group 303 moves axially along the optical axis, causing the combined focal length of the sight's optical system to change, and the image of the first zoom lens group 303 also moves accordingly. To maintain the image plane of the sight's optical system stationary, the second zoom lens group 304 is moved according to a specific pattern simultaneously with the movement of the first zoom lens group 303, so that the image point of the first zoom lens group 303 remains in its original position after passing through the second zoom lens group 304. The movement pattern of the second zoom lens group 304 is nonlinear and corresponds to the movement of the first zoom lens group 303 (in other embodiments of the present invention, the movement of the first and second zoom lens groups 303, 304 can be coordinated by a precision cam). Light passes through the image transfer lens group 3 to form an image on the second image plane, and then is emitted as parallel light through the eyepiece group 2 to form an image on the retina.

[0081] The parameters of the optical system of the scope of this embodiment meet the following requirements: the spherical aberration, axial chromatic aberration, and sine difference of the optical system are all less than λ / 4, meeting the imaging standard; the system distortion value is less than 3% within the full magnification and full field of view, and the field curvature value is within 2SD, meeting the tolerance of the telescope system aberration. For the structure and optical performance of the scope optical system at 1x and 8x, please refer to Figures 1 to 10 .

[0082] In the zoom curve, the displacement of the zoom group and the cam rotation angle are in an exponential function relationship, and the displacement of the compensation group and the displacement of the zoom group satisfy Newton's law.

[0083] Furthermore, the eyepiece group 2 is connected to the mirror tube 8 through a connecting ring; the eyepiece group 2 and the connecting ring are connected by threads, and a diopter adjustment handwheel is provided on the outside of the eyepiece group 2. By rotating the diopter adjustment handwheel, the eyepiece group is driven to move axially, and the diopter value is adjusted to compensate for the observer's vision.

The inner optical rod end of the zoom rotating screw 10 passes through the zoom opening groove of the lens tube 8 and is located in the waist-round groove of the zoom tube 510.

[0089] The principle of magnification is as follows: the magnification handwheel 7 and the inner end of the magnification handwheel 7 drive the magnification tube 510 to rotate, and then drive the two sliding screws 515 to move in the first magnification curve groove and the second magnification curve groove through the first magnification curve groove and the second magnification curve groove on the magnification tube 510.

[0117] This embodiment optically addresses the issues of large parallax and chromatic aberration at high magnification, as well as jerking of the zoom handle in existing high-magnification scopes. To address these issues, this embodiment utilizes a combination of high-refractive-index and high-dispersion materials, and simultaneously designs the field lens, front lens, and rear lens to smooth the light flow and reduce system sensitivity. The functional relationship between the zoom group and the zoom tube (cam) is set to an exponential function, reducing the pressure angle between the zoom group and the compensation group. This results in smoother rotation of the zoom handle during zooming and reduces parallax.
