Abstract

The present invention relates to a kind of optical eyepiece device capable of turning at arbitrary angle and its regulation method. It is mainly characterized by that between objective group and eyepiece group of optical instrument the prism, plane mirror and mechanized synchronous driving element are set. When the eyepiece group is regulated and turned, the optical element also can be driven to make the light injected from objective group pass through optical element, and be re refracted, reflected and more projected to the visual line of eyepiece group, so that when the objective group can be turned and moved to arbitrary angle, the visual line still can be aligned with same object, and the optical eyepiece device also can make visual line of light of optical instrument still retain between objective group and eyepiece group and not produce deflection.

Description

The optics eyepiece device and the method for adjustment thereof of angle rotatable

The present invention is relevant a kind of optics eyepiece device and method of adjustment thereof, be meant especially a kind of in conjunction with prism, face mirror and mechanical hook-up, make the eyepiece group can be free at stationary shaft to optics eyepiece device and the method for adjustment adjusting, rotate.

Existing optical instrument, as telescope, microscope and other relevant optical equipments, its eyepiece all adopts the design of fixed angle, be that to be projected to the eyepiece group be to be fixed angle can't move for optical axis or sight line, then there is the display of friendship to be installed in the eyepiece group in recent years, rotate synchronously by display and eyepiece, reaching can be in different angular observation object, but it has following shortcoming in use unavoidably:

1, the optical equipment of existing fixed sight line formula during use, as the angle that the light that changes objective end enters the eyepiece end, often need move whole tool instrument and do many adjustment, causes the inconvenience in the use.

2, installing the pattern of display in the eyepiece group additional, then is again with CRT or the video picture of LCD system, in the processing of circuit process, can produce, to increase noise earlier through electronic signal process, reduces resolution.

Purpose of the present invention aims to provide a kind of optics eyepiece device and method of adjustment thereof of angle rotatable; It is between objective lens and eyepiece group, setting is by the optical element of mechanical drive, control, when adjustment eyepiece group is rotated on a fixation axle center, the light beam that the order objective lens receives, projects, can effectively be projeced into the eyepiece group, make the eyepiece group rotate, be shifted, all do not influence the observation effect to object, this is a fundamental purpose of the present invention.

Optics eyepiece device and method of adjustment thereof according to this kind angle rotatable of the present invention, it is by optical element such as prism, level crossing etc., the light that objective lens is throwed is reflected, is reflected, the eyepiece group is gone in projection again, do not need via processing of circuit, avoid producing noise, guarantee image quality, this is an another object of the present invention.

The object of the present invention is achieved like this: the present invention is made up of objective lens, housing, optical elements sets, transmission device group and eyepiece group at least; Wherein optical elements sets comprises refracting telescope, a prism and a rotating level crossing of a fixing installing; The transmission device group is made up of the large and small different gear sets of two diameters synthetic a driving gear set and a follower gear by setting firmly a driving gear, on the rotor plate; Objective lens is installed in a side of housing, prism is installed in the rear of objective lens, the refracting telescope of fixing installing is arranged on the housing madial wall corresponding to prism, rotating level crossing, be mounted in the transmission device group on the follower gear, the traditional thread binding opposite side of being located at housing of eyepiece, and drive portion is engaged with rotor plate with fixed screw, driving gear set is hubbed on one and is fixedly arranged on the pivot of housing sidewall, and fix with fixed screw, partly meshing of driving gear and driving gear set, driving gear set smaller-diameter portion and follower gear engagement than major diameter.
