Abstract
The utility model relates to a miniature telescope, which is used for watching sporting contests, stage programs, tour, etc. The utility model comprises an objective lens, reflecting lenses and an eyepiece; the rear of the objective lens (1) is provided with the reflecting lens (2) and the front of the eyepiece (4) is provided with the reflecting lens (3); the reflecting lenses are separately connected with the objective lens and the eyepiece into about 45 DEG. The utility model has the advantages of simple structure, light weight and small size; the thickness of the utility model can be within 2 centimeters; the utility model having a comfortable feeling effect can improve the practicality of the telescope in life.
Description
The utility model relates to a kind of miniature spectacle telescope that is used to watch sports tournament, stage program and tourism etc.
Existing telescope, its optical system has only object lens, eyepiece to form, object lens are convex lens, eyepiece is concavees lens, come from the outside the light of object through converging behind the object lens, upright by forming behind the eyepiece, as to amplify virtual image, the length of lens barrel equals objective focal length and deducts eyepiece focal length, so the telescope volume is bigger, especially is difficult on the length shorten, even set up spectacle frame, because telescopical centroidal distance people's the bridge of the nose is far away, the arm of force is long, therefore can not be worn over for a long time on the eyes, for application, very big limitation is arranged.
Task of the present utility model is will shorten length, reduce volume, realizes the miniature spectacle telescope of real practicality.
Task of the present utility model is that following structure is finished: telescope is by object lens (1), catoptron I (2), catoptron II (3), eyepiece (4), mirror leg (5), lens barrel (6), adjustment structure (7) and mirror case (8) are formed, be provided with catoptron I (2) in the back of object lens (1), be provided with catoptron II (3) in the front of eyepiece (4), top one side of catoptron I (2) and mirror case (8) forward position horizontal sides angle be 35 spend to 55 the degree between (the best be 43 spend to 47 the degree between), the vertical edge angle of its forward position and mirror case (8) is spent to (the best is spent between 20 degree 15) between 35 degree 10, following one side of catoptron II (3) and mirror case (8) forward position horizontal sides angle be 35 spend to 55 the degree between (the best be 43 spend to 47 the degree between), the vertical edge angle of its forward position and mirror case (8) is spent to (the best is spent between 20 degree 15) between 35 degree 10, make direction of light by vertically transferring to laterally like this, increase light path, reach the way of reduced volume.
Be elaborated below in conjunction with accompanying drawing:
Accompanying drawing 1 is the telescopical stereographic map of the miniature spectacle of the utility model.
Accompanying drawing 2 is internal views that the utility model removes the mirror case front surface.
The utility model Miniature glasses type telescope is made up of object lens (1), speculum I (2), speculum II (3), eyepiece (4), mirror leg (5), lens barrel (6), governor motion (7) and mirror case (8).
Object lens (1) are convex lens, and it is fixed on the lens barrel (6), and lens barrel (6) can move forward and backward by governor motion (7); Eyepiece (4) is concavees lens, is fixed on the mirror case (8), and two eyepiece center distance are the human eye spacing; To (the best is that 43 degree are to 47 degree) between 55 degree, spend to (the best is that 15 degree are to 20 degree) between 35 degree 10 by the vertical edge angle of its forward position and mirror case (8) at 35 degree for the angle of top one side of speculum I (2) and mirror case (8) forward position horizontal sides; The angle of following one side of speculum II (3) and mirror case (8) forward position horizontal sides (is spent to 47 degree the bests with 43) between 35 degree are spent to 55, and the vertical edge angle of its forward position and mirror case (8) is (the best is between 15 degree are spent to 20) between 10 degree are spent to 35.
Wherein object lens (1) and speculum I (2) all are positioned at the first half of mirror case (8), and eyepiece (4) and speculum II (3) all are positioned at the Lower Half of mirror case (8). Speculum I (2) is in object lens (1) back, and speculum II (3) is in eyepiece (4) front. Mirror leg (5) links to each other with mirror case (8) by hinge.
Ambient light arrives catoptron I (2) back reflection by object lens (1) and goes up (light arrival the right of left side object lens to catoptron II (3), the right object lens light arrives the left side), reflex to eyepiece (4) again, like this, make the physical length of optical path length equal the distance that binocular case thickness adds two catoptron I, II center.Therefore light path increases manyfold, and telescope length is shortened greatly, forms real miniature telescope.
Introduce a kind of embodiment of the present utility model below.
Mirror case (8) thickness 2cm, two catoptron I, II center distance 7cm, object lens (1) focal length 10cm, eyepiece (4) focal length 1cm, top one side of catoptron I (2) is 45 degree with the angle of mirror case (8) forward position horizontal sides, the vertical edge angle of its forward position and mirror case (8) is 17 degree, following one side of catoptron II (3) is 45 degree with mirror case (8) forward position horizontal sides angle, the vertical edge angle of its forward position and mirror case (8) is 17 degree, set up mirror leg (5), can become and amplify 10 times miniature spectacle telescope.
This telescope length is extremely short, 2cm only, and enlargement ratio can reach 10 times, and simple in structure, be worn over the sense of not having discomfort on the eyes for a long time, many aspects that can apply to live improve the telescope practicality greatly.
Claims (2)
1, a kind of by object lens (1), eyepiece (4), mirror leg (5), lens barrel (6), the miniature spectacle telescope that governor motion (7) and mirror case (8) are formed, it is characterized in that, be provided with catoptron I (2) in the back of object lens (1), be provided with catoptron II (3) in the front of eyepiece (4), top one side of described catoptron I (2) and mirror case (8) forward position horizontal sides angle be 35 spend to 55 the degree between, the vertical edge angle of its forward position and mirror case (8) is spent between 35 degree 10, following one side of described catoptron II (3) and mirror case (8) forward position horizontal sides angle are 35 to spend between 55 degree, the vertical edge angle of its forward position and mirror case (8) 10 spend spend to 35 between.
