Abstract
The utility model relates to a galileian telescope which can change magnification. The utility model is formed by combining eye lenses with two or more than two different focal lengths and the same objective lens. The utility model is used for people to watch sports games and literary programs when low range and large viewing fields are adopted; the utility model is used for people to watch specific scenes and fine details in performance when high multiplying power is adopted. Thus, the telescope has effects of two telescopes.
Description
The utility model is a kind of telescope, belongs to the Galileo telescope that can change enlargement factor.
The Galileo telescope has simple in structure, and imaging is the advantage of erect image, but along with the raising field angle of enlargement factor sharply reduces.When enlargement factor was 8 times, field angle had only about 3 °, the visual field reduce to observe sports tournament, theatrical items are very unfavorable, thereby the Galileo telescope generally is in low power on the market, enlargement factor has only about 3 times.
The purpose of this utility model just is to improve the telescopical enlargement factor of Galileo, increases its field angle simultaneously, so that the wealthy scope of application of opening it.
In order to realize the purpose of foregoing invention, the technical solution unlike the prior art that the utility model provides is: become times object lens that the Galileo telescope is made by optical plastic, optical glass, eyepiece, and eyepiece conversion equipment, focus control and form by the lens barrel that metal materials such as engineering plastics, aluminium alloy are made.The eyepiece that two or more different focal are wherein arranged cooperates with object lens respectively, obtains the Galileo telescope of different amplification.
By focus control, lens barrel is outwards stretched out, when being equipped with high power ocular, obtain powerful Galileo telescope.When the inside contraction of lens barrel is equipped with low power ocular, obtain the Galileo telescope of low range.The eyepiece conversion equipment adopts guide type, mirror bowl formula and other forms etc.This change times Galileo telescope can be the monotubular formula, also can be double-cylinder type.
Accompanying drawing 1 is a schematic diagram of the present utility model
Accompanying drawing 2 is simple knot compositions of the present utility model
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Object lens among the figure (1) place lens barrel the place ahead objective tube (4), and eyepiece (2), (3) place lens barrel rear eyepiece stalk (5), and lens barrel can stretch, and match with object lens (1) by conversion equipment (6) in eyepiece (2), (3).
Become times Galileo telescope, watch sports tournament, theatrical performance with the big visual field of low range.Watch close-up shot with the high magnification visual field, the details in the performance.Such tool telescope has been got the telescopical effect of two tools.
Claims (2)
1, a kind of change times Galileo telescope of being made up of object lens, objective tube, eyepiece, eyepiece stalk, focus control, eyepiece conversion equipment is characterized in that: the eyepiece that two or more different focal are arranged.
2, change according to claim 1 times Galileo telescope, it is characterized in that: the eyepiece of different focal matches with object lens respectively by the eyepiece conversion equipment.
