Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of mini microscope that is used for the digital micrograph image capture device, concrete technical scheme is as follows:
A kind of mini microscope that is used for the digital micrograph image capture device comprises lens barrel, object lens and eyepiece, and object lens and eyepiece are located at the lens barrel rear and front end respectively, and the optical axis coincidence of the two.The emergent pupil of the rear end of described lens barrel, its position is at the eyepiece rear side.The position of this emergent pupil needs fully outer moving, emergent pupil can be complementary with the entrance pupil aperture and the position of digital image collection equipment such as digital camera, mobile phone or single anti-digital camera, make observed micro-image can be full of the film viewing screen of these equipment or can be full of 90% of film viewing screen at least, to guarantee that the observer can observe comfily.
Also comprise the graduation mirror, the graduation mirror is located in the lens barrel, between object lens and eyepiece; The graduation mirror is a planar lens, is provided with scale on the graduation mirror, is convenient to the size that the user measures measured micro-object each several part.The arrangement of graduation mirror will be eliminated parallax fully.
Also comprise plexiglass tent, plexiglass tent is connected the lens barrel front end, cover on object lens before.The shape of plexiglass tent can have difference, and its end face plays the positioning action of observation.With its end face is locating surface, and the whole microscope that tilts slightly also can reach focusing action, to obtain micro-image the most clearly.
Described lens barrel is provided with the object lens focusing structure.Specifically, described object lens focusing structure is a focusing ring; Described object lens are located on the focusing ring, and lens barrel is connected with focusing ring.
Described object lens and lens barrel structurally removably connect.As long as be replaced by the object lens of different focal for the object lens of the mini microscope of different model, then the mini microscope exhibition of can further drawing together easily be the microscope of different multiplying, enlarges microscopical usable range, and its length overall does not increase too much.
The length of described lens barrel is 70～80 millimeters.
Compared with prior art, digital camera, mobile phone or single anti-digital camera etc. can combine with the utility model, the digital camera microscope, mobile phone microscope or the single anti-digital camera microscope that become different model and purposes go to observe or take micro-object, can unload again after using up.The application of these instruments comprises: police criminal detection, the mine locating of geology ore assay, agricultural crops gardening rice plants disease and pest are chosen seeds, wool spinning cotton spinning silk spinning embroidery textile material is relatively selected with selection, museum's archaeology verification retrieval, bioconversion medium, information acquisition, dermatology, material science and jewelry and identify etc.
The characteristics of this mini microscope also have:
(1) for the microscope of different model, only need change the object lens of different focal, multiplying power can reach tens times, and 100 times, even more than 200 times, yet its total length but has only 75 millimeter.
(2) this mini microscope is a separate component, as long as mix different interfaces, just can conveniently be expanded into the different digital camera microscope of function, mobile phone microscope and single anti-digital camera microscope etc.
Description of drawings
Fig. 1 is a basic structure principle schematic of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:
A kind of mini microscope that is used for the digital micrograph image capture device, comprise lens barrel, object lens and eyepiece, object lens and eyepiece are located at the lens barrel rear and front end respectively, and the optical axis coincidence of the two, it is characterized in that described lens barrel rear end gets emergent pupil, its position is at the eyepiece rear side, and emergent pupil needs fully outer moving; The length of described lens barrel is 70～80 millimeters.
Also comprise the graduation mirror, the graduation mirror is located in the lens barrel, between object lens and eyepiece; The graduation mirror is a planar lens, is provided with scale on the graduation mirror.
Also comprise the machine cloche, plexiglass tent is connected the lens barrel front end, cover on object lens before.Plexiglass tent and lens barrel are to removably connect.
For the mini microscope of different model, can be provided with the object lens focusing structure on the described lens barrel.Described object lens focusing structure is a focusing ring; Described object lens are located on the focusing ring, and lens barrel is connected with focusing ring.
Described object lens and lens barrel are to removably connect.For the mini microscope of different model, as long as change the object lens of different focal, then mini microscope can extend further to the microscope of different multiplying easily, and its length overall does not increase too many.
Principle of work of the present utility model (with reference to figure 1)
Among Fig. 1, the 1st, object lens; The 2nd, the graduation mirror, the graduation mirror has accurate scale on the surface; The 3rd, eyepiece; The 4th, plexiglass tent; The 5th, emergent pupil.
