Description

Multifunctional microscopic imaging equipment

Technical Field

The utility model belongs to the microscopic imaging field, concretely relates to multi-functional microscopic imaging equipment.

Background

With the development of optical imaging technology, more and more instruments and devices and consumer products are added with imaging devices, the diversity and importance of functions of the imaging devices are higher and higher, and various imaging modules are layered on the market, but in the field of microscopic imaging, no mature modular product is available at present.

Regarding imaging module in the aspect, present ordinary macro module is mostly the manual focusing module of installing wide angle macro camera lens, and it is for remedying the not enough defect of illumination, often simply arranges illuminating lamp pearl around the camera lens and throws light on to its formation of image field of vision in, like the chinese utility model patent publication that application number is CN200720057106.0 to and the chinese utility model patent publication that application number is CN201320093315.6, the major defect of this scheme is:

1) due to the limitation of the wide-angle macro lens, the size of the wide-angle macro lens is large, so that the module cannot automatically focus, manual focusing operation is inconvenient in actual use, clear images cannot be directly shot, the wide-angle macro lens cannot realize ultra-micro imaging and micro imaging, and the requirements of magnification and resolution cannot be met.

2) The illumination light source is lamp pearl direct irradiation, removes the in-process at the object space, and very big change can take place for the even degree of actual illuminating effect, especially under the super microspur imaging environment that the object plane is very close, and the illumination can be seriously not enough, and this kind of illumination mode has stronger and comparatively concentrated reflection when observing high anti-surface, influences the imaging quality.

Change illumination light source outgoing angle, add the guide part for light, and methods such as control LED luminous angle can all make the illumination problem improve, for example, Chinese utility model patent that application number is CN201720470643.1 discloses a case that improves to the illumination of macro imaging module through the structure of similar optic fibre, the specific luminous angle of its lamp pearl has also made the requirement, the advantage of this scheme is that the limited problem of macro imaging module light filling has been solved, but its part is more, the structure is too complicated, the installation degree of difficulty is higher, be unfavorable for the miniaturization and the integration of module, and cost-push.

The chinese utility model with application number CN201920098694.5 discloses a scheme for improving a macro imaging module by a light guide structure, which has the advantages of making the illumination of the macro imaging module uniform and controlling the overall volume, however, the optical lens with symmetrical structure integrated with the auto-focusing module involved in this solution has no finished product at present, secondly, the manufacturing difficulty and the cost are higher, and simultaneously, the volume and the weight of the lens group are larger than those of the lens group driven by a voice coil motor, so the design difficulty of the focusing structure is increased, the overall size of the camera module is possibly large, which is not beneficial to the miniaturization of the whole module, moreover, the integrally packaged symmetrical structure lens only can be used for a single application scene, different symmetrical combinations can not be used according to different application scenes, which is not beneficial to the serialization of the module, and the adaptability of the module under multiple application scenes is reduced. In addition, the imaging module in the scheme can only perform reflection illumination on the surface of an object through the light guide structure of the imaging module, and is not matched with corresponding parts to realize transmission illumination under the condition of observing a slide specimen and the like, so that the application value of the imaging module in the biomedical field to which the imaging module is directed is reduced.

Regarding the aspect of microscopic equipment integrating a microscopic imaging module, most of the current portable digital microscopes adopt a mode of manually focusing through a mechanical moving structure by combining a microscope lens and a photosensitive chip and transmitting image signals to a mobile phone or a computer through a usb data line, for example, a digital microscope disclosed in the chinese utility model patent publication with the application number CN201721373383.2 adopts a mechanical structure to move an integrated eyepiece assembly up and down so as to achieve the purpose of manual focusing; for example, the chinese utility model patent publication with the application number cn201920345625.x, the zoom camera with the zoom function adopts a mechanical structure to move the position of the photosensitive chip up and down, thereby realizing manual focusing. Simultaneously, above two kinds of microscope products all adopt around the camera lens simple annular to arrange exposed led lamp pearl and throw light on, and the main shortcoming of this type of scheme is:

1) because the adopted lens has larger volume and the shell needs to reserve enough space for the mechanical movement range, the size of the product along the optical axis direction of the optical system is larger, the whole body can only be designed into a cylindrical shape or a similar shape, and the possibility that various external shapes correspond to various application scene requirements is reduced

2) Because the mechanical focusing structure needs manual adjustment, the use and operation of the product are complex, and clear images of observed objects cannot be obtained in a very short time.

3) Because the LED lamp beads are used for directly illuminating the observed object, the illumination uniformity is not ideal, and strong glare is easy to appear when the high-reflectivity surface is illuminated and observed, so that the imaging quality is influenced.

4) The experience of using the application scene for observing the biological slide is not friendly, the structure for positioning and fixing the biological slide is not provided, and the standardized surface is not fixed on the back surface of the slide to be used as the imaging background

Regarding the illumination device used for observing the slide specimen by the small-sized microscopic imaging equipment, when observing the observation object commonly used for biological detection such as the slide specimen in a microscopic way, the slide specimen generally needs to be illuminated in a transmission way, for example, the illumination light source positioned at the bottom of the slide specimen in the traditional microscope, and when observing the specimen sample with high transparency or without dyeing, the dark field illumination light source is used in the traditional microscope, and the light sources of the two traditional microscopes are complex in structure, large in volume and need independent illumination light sources. In the microscope product of portable observable slide sample on the market at present, its light source of illumination is mostly for setting up at slide sample rear, even light board or the lamp pearl of camera lens opposite side promptly, like the portable microscope that chinese utility model patent publication that application number is CN201721678198.4, this microscope is used for cooperating the mobile device camera to carry out the microscopic observation to slide sample. The lighting source is a lamp panel arranged at the back of the slide and opposite to the lens, the light source needs a battery to supply power to the light source, and only the transmitted lighting light can be provided to observe the slide specimen in a bright field. Meanwhile, the lighting source structure has the functions of positioning and fastening the slide specimen, the slide specimen needs to be tightly pressed by a manual adjusting knob, the moving range of the slide specimen in the limiting structure is limited, and if the distance between the position of the specimen sample in the slide and the symmetrical center of the width direction of the slide is too large or the range of the sample is larger, an observation blind area can appear. Also, as disclosed in the chinese utility model with application number CN201610935569.6, the light source of the multiband LED anti-transillumination stage also needs to be powered by an additional battery, and the overall size is large.

The miniaturized ultramicro-distance imaging module and the imaging equipment using the miniaturized ultramicro-distance imaging module have great application prospect and value in the fields of biomedical treatment, intelligent identification, consumer electronics with professional application and the like, and products capable of comprehensively solving the problems are lacking at present.
