Abstract
The utility model relates to a Paul telescope with super large sight, which comprises an objective lens (1), a Paul reversed image system and an eye lens system, wherein, the eye lens system comprises a field lens (6) and an eye lens (7), and the Paul reversed image system comprises plane reflective mirrors (2), (3), (4) and (5); the objective lens (1) is arranged between the plane reflective mirrors (2) and (4). The utility model has the advantages of shorter lens cone, better quality, convenient carrying, simple structure, lower cost, shorter optical route, larger angle of view and better imaging quality.
Description
The utility model relates to a kind of Borrow's formula telescope.
At present, Borrow's formula telescope, its Borrow's formula inverted image system places between object lens and the eyepiece system, and lens barrel is longer, and structure is comparatively complicated, and the distance of light is longer; Field angle is less in addition, imaging second-rate.
The purpose of this utility model provides Borrow's formula telescope, and it simplifies its structure by the length of the distance shortening lens barrel of shortening light, and manufacturing cost is reduced, and field angle is bigger, and image quality is better.
The utility model is realized by following technical scheme: it comprises object lens, Borrow's inverted image system and eyepiece system, and wherein eyepiece system comprises field lens and eyepiece, and Borrow's inverted image system comprises 4 plane mirrors, and object lens place between two plane mirrors.
Above-mentioned described eyepiece system contains two or more than two field lens at least.
Above-mentioned described object lens and eyepiece are non-spherical lenses.
Above-mentioned described 4 plane mirrors and object lens all are embedded into the body frame the inside.
The utility model compared with prior art has following advantage: lens barrel is shorter, and lighter weight is easy to carry, simple in structure, and cost is lower, and the distance of light is shorter, and field angle is bigger, and image quality is better.
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is an index path of the present utility model;
Fig. 2 is the wiring layout of embodiment of the present utility model;
Fig. 3 is the A-A cut-open view of Fig. 2.
As shown in Figure 1, the utility model comprises object lens (1), Borrow's inverted image system and eyepiece system, wherein eyepiece system comprises field lens (6) and eyepiece (7), Borrow's inverted image system comprises plane mirror (2), plane mirror (3), plane mirror (4) and plane mirror (5), and object lens (1) place between plane mirror (2) and the plane mirror (4); As shown in Figure 1, light enters plane mirror (4) through object lens (1) after reflecting through plane mirror (2), plane mirror (4) reflexes to plane mirror (3) with incident ray, and plane mirror (3) reflexes to light plane mirror (5) again, enters eyepiece system then.
Above-mentioned described eyepiece system contains two or more than two field lens (6) at least, and object lens (1) and eyepiece (7) can be non-spherical lens plane mirror (5).
Embodiment: as Fig. 2, shown in Figure 3, plane mirror (2), plane mirror (3), plane mirror (4) and plane mirror (5) and object lens (1) all are embedded into body frame (8) the inside, make structure of the present utility model simpler; Plane mirror (3), plane mirror (4) are perpendicular to body frame plane (9); Plane mirror (3) forms an angle of 90 degrees with plane mirror (4); Plane mirror (2), plane mirror (5) become miter angle with body frame plane (9), constitute miter angle with optical axis simultaneously, and object lens (1) place between plane mirror (2) and the plane mirror (4).
Claims (4)
1, ultra-large vision field Borrow formula telescope, comprise object lens (1), Borrow's inverted image system and eyepiece system, wherein eyepiece system comprises field lens (6) and eyepiece (7), Borrow's inverted image system comprises plane mirror (2), plane mirror (3), plane mirror (4) and plane mirror (5), it is characterized in that object lens (1) place between plane mirror (2) and the plane mirror (4).
2, ultra-large vision field Borrow formula telescope according to claim 1 is characterized in that eyepiece system contains two or more than two field lens (6) at least.
3, ultra-large vision field Borrow formula telescope according to claim 1 is characterized in that object lens (1) and eyepiece (7) are non-spherical lenses.
4, ultra-large vision field Borrow formula telescope according to claim 1 is characterized in that plane mirror (2), plane mirror (3), plane mirror (4) and plane mirror (5) and object lens (1) all are embedded into body frame (8) the inside.
