Preferably, described camera lens axial limiting sleeve pipe is provided with three screw elements, and described tight shot is provided with three limited posts, by the assembly relation of three screw elements and three limited posts, when realizing that dial rotates, changes the axial height position of camera lens.
Preferably, the utility model also comprises a protection glass, and described protection glass is bolted in the top of tight shot.
As further improvement, the utility model also comprises: a LED takes illuminating lamp, and described LED takes the top that illuminating lamp is connected in camera lens axial limiting sleeve pipe; One transparent rack, described transparent rack and camera lens locating shaft are spirally connected to limit casing.
The portable manual adjustable type that the utility model is set forth focuses electron microscope, and compared with prior art, its beneficial effect is:
1, the mode of using camera lens axial limiting sleeve pipe to add interior worm screw dial superposing control realizes the Position Control between object, tight shot and the imageing sensor is reached the function of microcosmic amplification imaging; Take into account the switching that realizes macroscopical shooting, microshot and microcosmic bust shot simultaneously;
2, with cheap relatively cost, simple and practical structure, independent realize reliably focus electron microscope series products function expansion, integrated professional, ease for operation, portability, practicality are in one.
3, the utility model electron microscope can use as the common digital camera that focuses, and can use as electron microscope again.Can directly observe the scene that microscope will be taken immediately by display screen, scene can be taken into photo simultaneously, video recording etc. is recorded in the storage card as data storage.
Description of drawings
Accompanying drawing 1 focuses the STRUCTURE DECOMPOSITION schematic diagram of electron microscope for the utility model portable manual adjustable type;
Accompanying drawing 2 is the assembling view of Fig. 1.
Embodiment
Below, in conjunction with the accompanying drawings and embodiment, portable manual adjustable type of the present utility model is focused electron microscope be described further, so that clearerly understand the utility model technological thought required for protection.
As shown in Figure 1 and Figure 2, the portable manual adjustable type focuses electron microscope, comprising: tight shot 1, interior worm screw dial 2, camera lens axial limiting sleeve pipe 3, protection glass 4, LED take illuminating lamp 5, transparent rack 6, pedestal 7, transducer 8.Transducer 8 is fixedly welded on the pedestal 7, camera lens axial limiting sleeve pipe 3 by screw on pedestal 7, interior worm screw dial 2 is enclosed within outside the camera lens axial limiting sleeve pipe 3, camera lens axial limiting sleeve pipe 3 is provided with three screw elements, tight shot is provided with three limited posts, by the assembly relation of three screw elements and three limited posts, when worm screw dial 2 rotates in realizing, change the axial height position of camera lens.Protection glass is bolted in the top of tight shot, be connected in the top of camera lens axial limiting sleeve pipe, realize fixedlying connected of transparent rack 6 and camera lens axial limiting sleeve pipe 3 thereby the internal thread by transparent rack 6 and camera lens locating shaft are spirally connected to the coupling of the screw thread at limit casing 3 tops; LED takes illuminating lamp 5 and is provided with a plurality of projections, the screw thread that is connected with transparent rack 6 on the camera lens axial limiting sleeve pipe 3 is provided with number of slugs identical, the draw-in groove of position relationship consistency, LED shooting illuminating lamp 5 is connected on the camera lens axial limiting sleeve pipe 3 by the corresponding relation of projection and draw-in groove.
Operation principle: tight shot 1 is by three screw elements of camera lens axial limiting sleeve pipe and the assembly relation of three limited posts on the tight shot 1, when worm screw dial 2 rotates in realizing, change the axial height position of camera lens, at the top of camera lens axial limiting sleeve pipe 2, fixed L ED take illuminating lamp 5 and transparent rack 6 control objects and transducer apart from x.Subject supports by transparent rack 6, fixed object and transducer 8 apart from x, promptly x is a definite value.Re-use worm geared principle, thus the distance that 3 pairs of spacing conditions control tight shots 1 of worm screw dial 2 and camera lens axial limiting sleeve pipe change to realize between control object distance u(object and the camera lens at the axial location between object and the transducer 8 in rotating) and the distance between v(camera lens and the transducer apart).The object distance direction is a positive direction.When object distance and at a distance of between satisfy optical male lens dioptric imaging principle: 1/u+1/v=1/f(f is the focal length of camera lens), during the x=u that satisfies condition simultaneously+v:
When u=2f is the focal length that object distance equals 2 times, and when satisfying the condition of 1/u+1/v=1/f and x=u+v, promptly be the microshot pattern, product function is consistent with the microshot principle that focuses digital camera;
Work as 2f〉u〉f is object distance between the focal length of 1 times of focal length and 2 times, and when satisfying the condition of 1/u+1/v=1/f and x=u+v, promptly be microcosmic bust shot pattern;
Simultaneously, the set design attitude of adjusting to the camera lens specifications when tight shot satisfies u during at a distance of v=f again〉the 2f object distance is during greater than 2 times focal length, promptly is macroscopical screening-mode, with to focus digital camera consistent.
Thereby realized the switching of macroscopical shooting, microshot and microcosmic bust shot.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection range of the utility model claim all according to technical scheme described above and design.
