Abstract
The utility model discloses a kind of high accuracy optical path adjusting mechanism, light enters optics through camera lens, and camera lens is fixed on objective carrier, optics mounting seat is fixed through focus adjustment screw, simultaneously as the effect of spring, make the distance between optics mounting seat and camera lens fixing.Then adjust adjusting screw, make regulating part be close to camera lens mounting seat, final regulating part constrains optics mounting seat jointly, when being allowed to movable and driving optics, can only be along the center of camera lens mounting seat, that is, the center of camera lens moves forward and backward.Because the pitch of focus adjustment screw is very little, when rotating a low-angle, the movable distance of optics is very little, and spring plays stable effect, thus accurate adjustment optics.
Description
Technical field
This utility model is related to optical technical field and in particular to a kind of high accuracy optical path adjusting mechanism.
Background technology
In the widely used spectrometric instrument in the fields such as optics, biology, chemistry, medical treatment, it is required for wherein optics device
Part carries out high accuracy and adjusts, so that optics reaches optimal optical property.And the optics governor motion of routine is entering
When row is adjusted, the regulation in a direction influences whether the precision of other degree of freedom, and after carrying out direction regulation, it is right to need
Other degree of freedom re-start regulation again, so that adjustment part volume is excessive, and due to the single degree of freedom cannot be adjusted,
It is mutually coupled seriously so as to be restricted in many applications.
In prior art, the single dimension regulation to optics coordinates 4 springs jointly to make frequently with 4 adjusting screws
With changing moving forward and backward of optics by the rotation of adjusting screw.As shown in Figure 1-2, current optical path adjusting mechanism
In, main inclusion line target 101, collimate camera lens 102, grating 103, grating mounting seat 104, imaging lens 105, imaging lens are pacified
Dress seat 106, rotates adjustable plate 107, up-down adjustment plate 108, focus adjustment plate 109, CCD110, CCD pedestal 111, collimates camera lens
Mounting seat 112, the right adjusting screw of up-down adjustment plate 113, the left adjusting screw of up-down adjustment plate 114, focus adjustment spring 115, burnt
Away from adjustable plate adjusting screw 116, up-down adjustment plate fixing screws 117.During use, turn focus adjustment plate adjusting screw 116, by
In the effect of focus adjustment spring 115, the longitudinal separation of only this screw changes, the longitudinal separation of other three screws
Not changing, thus reaching the purpose adjusting a dimension, according to final image quality, adjusting four focus adjustment respectively
Plate adjusting screw 116, obtains the optimal optical signal of final line target.
The structure of this governor motion carry out Anterior-Posterior adjust when, because being fixed with of adjusting screw is very big
Gap, lead to Anterior-Posterior to also result in optics up and down during adjusting or move left and right, also can lead to optics
Device rotates motion, so that regulating effect is had a greatly reduced quality, and can only again other degree of freedom be readjusted, so that adjusting

The screw claiming.
The using method of above-mentioned high accuracy optical path adjusting mechanism, comprises the steps：
S1, when needing to carry out optical path adjusting, is first screwed down adjusting screw so that the tune threadeded with adjusting screw
Section part is gradually adjacent to the projection of described camera lens installation through-hole and is embedded in the part in described cavity with screwing of adjusting screw
Outer surface, in the presence of the mutual power of regulating part, adjusting screw and camera lens mounting seat, described optics mounting seat exists
The movement of upper and lower, left and right four direction is rather limited；
S2 turns described focus adjustment screw forward or backward, and spring is compressed and forms stable elastic force, supports light
Learn device mounting seat to follow the movable of focus adjustment screw and move forward and backward, thus driving optics to move forward or backward
Dynamic, realize optical path adjusting.
The using method of above-mentioned high accuracy optical path adjusting mechanism, comprises the steps：
S1 screws adjusting screw, the female thread threadeded with adjusting screw adjust annulus with adjusting screw screw by
Gradually it is adjacent to the outer surface of the protuberance of camera lens mounting seat, then female thread adjusts annulus, adjusting screw and optics mounting seat shape
Become the position relationship of tightened relative, thus limiting the movement of described optics mounting seat upper and lower, left and right four direction；
When S2 adjusts optics before and after needing when focusing before and after needing, turn described focus adjustment screw, adjust
Section focus adjustment screw screws in forward or screws out backward, thus driving regulation optics mounting seat to be moved forward or rearward,
Adjust optics eventually to be moved forward or rearward.
The beneficial effects of the utility model are：
1st, pass through setting and have female regulating part and the adjusting screw matching, from four direction up and down to light
Learn device mounting seat to be constrained, when needing to carry out before and after's accurate translation to optics, turn focus adjustment spiral shell
Nail, due to the effect of spring, optics mounting seat accurately will be moved forward and backward with focus adjustment screw, thus driving light
Learning accurately moving forward and backward of device, without there is skew up and down, upper and lower or left and right rotation also will not occur.
2nd, because moving forward and backward of optics to be realized by the rotation of focus adjustment screw, and the pitch of focus adjustment screw
Very little, in such manner, it is possible to by the very little angle of focus adjustment screw rotation realize optics displacement very little away from
From such that it is able to high-precision be adjusted to optics.
