Microscope lens device with light guide function

Abstract

The invention relates to a microscope lens device with a light guide function, which is used for performing magnification observation on an object to be measured. The microscope lens device comprises a base, an observation unit, a plurality of light-emitting components and a light guide shade, wherein the observation unit is integrated onto the base and used for magnifying the observed image of the object to be measured; the light-emitting components are arranged on the base around the observation unit and used for providing an illuminating light source; the light guide shade is provided with a light guide part and a through hole, the light guide part is arranged on the base and can guide light, and the through hole is formed on the light guide part; the illuminating light source of the light-emitting components inclinedly illuminates the object to be measured through the body, thereby preventing light rays from being directly reflected back to the observation unit to form bright spots on the display screen; and shadow generated by the inclined illumination can also be utilized to further observe the three-dimensional structure of the object to be measured.

Description

technical field [0001] The invention relates to a microlens device, in particular to a microlens device with light guiding function. Background technique [0002] Due to the development and progress of science and technology, many imitated products and currencies can be manufactured very well, and it is becoming more and more difficult to identify them from the real ones. However, it is very difficult to identify the authenticity by means of visual observation with the naked eye. Therefore, when doing business, it is easy to cause loss of property due to the difficulty of identifying products and currencies with the naked eye, or even because of small features. The misjudgment of the naked eye recognition of the graphics will cause unnecessary disputes. [0003] For this reason, there are a number of microscopic devices on the market for consumers to use for finer identification, see figure 1 , figure 2 , is the microlens device disclosed in U.S. Patent No. 7,102,817B1, ...

AI Technical Summary

Problems solved by technology

[0004] The image sensor 121 is electrically connected to an external image device (such as a computer, not shown in the figure) for the user to observe the enlarged image of the object under test 100 captured by the image sensor 121, but It should be noted that since the above-mentioned microscope lens device itself does not have any light source to illuminate the object 100 to be measured, the image definition at high magnifications is not good, and it can achieve Microscopic magnification is therefore limited

[0005] Therefore, see image 3 , 4 , the inventor of the present case has developed a hand-held microscopic identifier 2, the microlens device 21 used in it has a light-emitting element 211 itself, and then illuminates it when observing the object to be measured 100, but, although the above-mentioned The microlens device 21 of the hand-held microscopic identifier 2 has its own light-emitting element 211, but it can only provide an illumination source perpendicular to the object under test 100. Therefore, when the object under test 100 has reflective materials (such as conductive solder joints on the circuit board), which will directly reflect the vertical light source back to the microscope lens device 21, and form bright spots on the display screen, thereby affecting the clarity of observation

Furthermore, since the microlens device 21 is observed from a top view, if the object under test 100 (or its surface) is in a three-dimensional shape, the direct light source cannot clearly cooperate to show its three-dimensional shape, thereby causing the user The exact three-dimensional structure of the object under test 100 cannot be clearly identified during observation

[0006] This shows that above-mentioned existing microscope lens device obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
