Embodiment two
In addition to zooming adjustment device 30 is in the outside applied force of lens, the optical surface of lens is made to occur may be used also outside elastic deformation
To be zoom lens to be arranged as hollow structure by adjusting, and utilize zooming adjustment device filled with transparent medium in its inner cavity
The volume size of the intracorporal transparent medium of 30 controller, 403 inside closing chamber 203 realizes, and the shape of transparent medium with
The variation of 203 shape of closing chamber and change always full of entire 203 body of closing chamber.
Fig. 5 is the basic structure schematic diagram of another zoom lens provided by the embodiments of the present application.As shown in figure 5, this is thoroughly
The first optical surface 201 and the second optical surface 202 of mirror surround hollow closing chamber 203, and filled with saturating in the closing chamber 203
Bright medium.Zooming adjustment device 30 include sequentially connected conduit 401, media storage chamber 402 and controller 403, conduit 401 also with
Closing chamber 203 is connected；Transparent medium in the media storage chamber 402 is filled with the closing for controlling by controller 403
Amount in chamber 203, so that the deformable optical surface generates elastic deformation.

Certainly, transparent medium can also be used with the transparent medium with the optical surface same color of lens according to practical application.Optics
The elastic size in face and the sticky size of transparent medium can select to determine according to actual needs, preferably clear medium and optical surface
Between have good adhesiveness.
It is controlled using controller 403 and the transparent medium in media storage chamber 402 is filled with the amount in closing chamber 203, in turn
Transparent medium pressure in adjustable closing chamber 203, for convex lens, when the pressure for increasing the transparent medium in closing chamber 203
Power makes transparent medium enter 203 body of closing chamber, and the intracorporal transparent medium of closing chamber 203 increases, and the optical surface of lens is by transparent
The pressure of medium increases, and the degree of convexity of base zoom lens increases, so that focal length becomes smaller；Conversely, when reducing in closing chamber 203
The pressure of transparent medium flows out to transparent medium in media storage chamber 402 from 203 body of closing chamber, and closing chamber 203 is intracorporal
Bright medium is reduced, and the pressure that the optical surface of lens is subject to reduces, and the degree of convexity of zoom lens reduces, so that focal length increases.It is right
In concavees lens, when the pressure for needing to increase the transparent medium in closing chamber 203, then enter transparent medium in 203 body of closing chamber,
The indent degree of zoom lens reduces, so that focal length becomes larger；Conversely, reducing the pressure of the transparent medium in closing chamber 203, make
Bright medium is flowed out from 203 body of closing chamber, and optical surface indent degree increases, so that focal length reduces.
Transparent medium in media storage chamber 402 is filled with the amount in closing chamber 203 by the control of controller 403, specifically can be with
Piston is set in media storage chamber 402, and controller 403 is realized by controlling the movement of piston, and the movement of piston can be with
It is realized by way of pushing and pulling or screwing, and can also be in the mobile direction setting scale of piston convenient for the control of piston motion amount
System.
Furthermore it is also possible to it is in conjunction with the embodiments a kind of, controller 403 is arranged in the lateral periphery of lens, is used for vertical
When applying drawing force on the optical axis direction of lens, when making the optical surface of lens that elastic deformation occur, transparent medium can pass through
Conduit 401 flows between 203 body of closing chamber and media storage chamber 402, and then the deformation range of optical surface can be made bigger, and
It adjusts and is easier to realize.For example, making optics of lens face curvature become smaller, transparent medium is passed through out of closing chamber 203 body when stretching lens
It crosses conduit 401 and flows into media storage chamber 402, conversely, increasing optics of lens face curvature when compression lens, transparent medium is from Jie
203 body of closing chamber is flowed by conduit 401 in matter storage chamber 402.
