Abstract
The utility model discloses an addition type optical zoom device for digital codes. The utility model is brought into force to engage with a microscope. The utility model is composed of an optical zoom unit and an image picking unit, wherein the optical zoom unit is an optical apparatus with a zoom group. One end of the optical unit is immovably connected on three cylinders of the microscope or the rear end of an eyeglass in the axial direction, and the other end is connected with the image pickup unit. To the microscope without a ZOOM device, the optical unit becomes a digital image picking device with continuous zoom. While to the microscope which is already equipped with a zoom structure, the optical unit provides a very good method for expanding the zoom range of the microscope, thereby without giving up the conventional microscope, and the digital image picking device with continuous zoom can be acquired, in which case the cost is saved, and the facility of the appurtenances which has maximal expansibility brings much convenience and adaptability for observation.
Description
Technical field
The utility model has related to a kind of for microscopical number optical zoom apparatus.
Background technology
But traditional microscope only has some the fixedly object lens of multiple or several multiples of gear shift, can not resemble to finish stepless multiple the continuous zoom mechanism and change.Change if want to obtain stepless multiple, need to abandon original microscope, again buy the new more expensive type that carries out stepless optical multiplier variation, increase cost that like this can be bigger.
The utility model content
The purpose of this utility model has just provided a kind of microscope optical zoom for additional numerical code that can carry out continuously optical zoom, easy to operate, simple in structure, low cost of manufacture.
In order to realize above-mentioned purpose, the utility model has been taked following solution:
Optical zoom for additional numerical code, implement for cooperating microscope, formed by optical zoom apparatus and image collecting device, optical zoom apparatus is the Optical devices with the zoom group, one end is fixedly connected on three of the microscope image pick-ups vertically, or the rear end of eyepiece, the other end is connected with image collecting device.
Above-mentioned optics becomes doubly, and device also can be arranged in the eyepiece stalk.
Above-mentioned optical zoom apparatus comprises fixing group and zoom group, sets up the focus control that is fixedly connected with optical zoom apparatus in image planes side.
Above-mentioned image collecting device can be camera, video camera, USB, 1394 card or figure acquisition and processing cards in order to the seizure and the record of image.
This device does not change the microscope that has now had, and has increased the function of new continuous zoom on original microscopical basis, realizes the microscopical multiplication factor expansion of logarithmic code.For the microscope that does not have the ZOOM device, just become the digital camera of continuous zoom; And for the microscope that zoom mechanism has been arranged, then the scope for its expansion zoom provides good method.The utility model is cost-saved, and this means of annex bring very big convenience and dirigibility to observation, has very high cost performance and good extendability.
Description of drawings
Fig. 1 is a structural drawing of the present utility model;
Fig. 2 is that optics of the present utility model becomes times principle schematic;
Fig. 3 is additional zoom optical schematic diagram of the present utility model;
Fig. 4 is simple and easy additional zoom optical schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, optical zoom for additional numerical code comprises a cover image collecting device 1 and a cover optical zoom apparatus 2.Image collecting device 1 is in order to the seizure of image and record, can be camera, video camera, USB, 1394 card or figure acquisition and processing cards.As shown in Figure 2, optics becomes that doubly to install 2 version generally be to comprise compensation group 21, the fixing group 22 in front and back and become doubly to organize 23 device.Zoom group 23 generally is to adopt negative lens group, and 21 of compensation groups may be positive lens groups or negative lens group.Also can not adopt fixing group 22, perhaps only adopt a fixing group 22, can select according to different application extension.Dispose respectively different continuous optical zoom devices 2 according to different microscopes, senior microscope adopts the optical zoom apparatus of mechanical compensation, zoom accurate stable; Middle-grade microscope adopts the zoom device of optical compensation, reaches good cost performance; Low-grade microscope adopts Manual optical device zoom, finely tunes the method for burnt compensation again, realizes the function of continuous zoom.
Get a microscope 3, the optics change is doubly installed 2 be inserted in microscope image pick-up three socket joint mouths 4 places, fix by 3 spacing dovetail grooves by lock-screw, promptly process and adjust in 3 two fixedly dovetail grooves, then as the position of lock-screw, the long spiro nail of marking closely screw or band handle such as use can for another point.The connected mode of the two is not only for above-mentioned oat tail groove structure, but all necessary characteristics that embody annex mode Fast Installation.Image collecting device 1 couples together by standard interface subsidiary on the optical zoom apparatus 2.
Optical zoom for additional numerical code of the present utility model also can adopt other embodiments.A kind of is to connect in eyepiece 5 rear ends, can adopt an anterior sleeve with the suitable optical zoom apparatus 2 of eyepiece 5 outside dimensions to entangle eyepiece 5 shells, and lock to connect with lock-screw; Another kind can take off eyepiece 5, and directly at the optical zoom apparatus 2 of eyepiece stalk 6 interior insertions, utilization closely cooperates with eyepiece stalk 6 inwalls, can realize that optical zoom apparatus 2 is connected with the firm of microscope 3, makes microscope 3 realize the continuous amplification of optical multipliers.
Wherein, as shown in Figure 2, optical zoom apparatus 2 comprises compensation group 21, fixing group 22, zoom group 23.Microscopie unit 3 as thing, becomes the image gathered and doubly installs 2 by optics, enter image collecting device 1 after treatment, finishes whole process.
As shown in Figure 3, in this light path, the image of gathering with microscopie unit 3 is a thing, doubly installed 2 o'clock by the optics change, constantly regulate to become and doubly organizes 5, carry out slight focusing, promptly change optics and become and doubly to install the image that 2 position just can obtain variation (amplify and dwindle), make change doubly become possibility.As: zoom group 23 to microscope 3 directions move from fixing group 22 more away from, it is more big that image collecting device 1 obtains picture, makes it become real optics and enlarge, and makes the microscope 3 that does not have the ZOOM device, just becomes the digital camera of continuous zoom.
As shown in Figure 4, in light path, optics becomes and doubly to install 2 and comprise change and doubly organize 23 and fixing group 22, and just not compensation group 21 is present in the device.When thing passes through optical zoom apparatus 2, device must compensate in focusing, can set up in image planes side and be fixedly connected with focus control (not providing among the figure) with optical zoom apparatus 2, in order to the location, in order to when appending to optical zoom apparatus 2 above the digit microscope 3, can produce and visual synchronous focal plane.Just change the position of optical zoom apparatus 2, slightly mobile to image capturing system, the way by the burnt compensation of this fine setting can obtain clearly image planes.Therefore, even the optics amplification has been carried out in the imaging of thing, make imaging parfocalization, clear again.
