Description

Technical Field

[0001] This utility model relates to the field of microscopes, specifically a short-path digital microscope designed to optimize the human-computer interaction process. Background Technology

[0002] In existing technologies, digital biological microscopes typically use LED light sources. The emitted light is converged by a condenser lens and focused within the condenser lens, ultimately landing on the object platform. The light passes through the object being observed, is refracted by the objective lens, enters the binoculars, and is then reproduced by the microscope's binocular lenses to form an image for the user to observe. The user adjusts the focusing knob to control the height of the object platform, ensuring that the object and the condenser lens are focused at the objective lens's focal point.

[0003] The power of LED light sources in existing digital biological microscopes is around 2-3W, which is relatively high.

[0004] Furthermore, the existing biological microscopes require significant space at the bottom for both the condenser and focusing lens, resulting in a tall overall microscope and a high eyepoint. Therefore, placing external display components, such as screens, on the sides is inconvenient for operators, as it cumbersome for prolonged observation with the head tilted to the side. Placing them at the top requires the operator to tilt their head back, causing neck discomfort and inaccurate viewing angles. Similarly, because the condenser and focusing lens are located at the bottom, the focusing wheel must be positioned at the rear, which is inconvenient. Both the condenser and focusing lens are optical components, requiring optical assemblies that are difficult to manufacture and adjust, leading to higher costs. Due to the long optical path and numerous optical glass elements, light loss is significant, resulting in high energy consumption to achieve the desired brightness. The structure also lacks sufficient space for integrating multimedia or computer components.

[0005] The patent application CN210923497U, which is close to a recent application, has a complex structure, requiring the use of a conical lens, a compound eye lens, and two optical glass components. It lacks a variable aperture structure, making it unable to control depth of field and sharpness. Based on its schematic diagram, its illumination effect is inadequate, failing to meet the needs of general microscopes, let alone be used in specialized applications. Utility Model Content

The visual structure is located at the upper end of the crossarm, the camera assembly is located inside the crossarm, the upper and lower ends of the microscope body are connected to the rear end of the crossarm and the rear end of the focusing base, respectively, the objective lens structure is located at the lower front end of the crossarm, the light source structure is located at the upper end of the focusing base, and the top is connected to the platform assembly. The light source structure includes a condenser lens, a variable aperture, a conical lens, an LED lamp, and a housing. The housing includes an upper housing, a lower housing, and a bottom cover. The condenser lens is fixed to the upper end of the upper housing by a condenser lens holder. The variable aperture is inserted between the lower end of the upper housing and the upper end of the lower housing. The conical lens is placed below the variable aperture. The LED lamp is placed at the lower end of the conical lens with its bottom end located at the upper end of the bottom cover. The variable aperture is equipped with an aperture lever that extends out of the housing.

[0008] Furthermore, the ratio of the distance from the LED lamp to the upper surface of the conical lens, the distance from the upper surface of the conical lens to the upper surface of the variable aperture, the distance from the variable aperture to the upper surface of the condenser glass, and the distance from the condenser glass to the upper surface of the stage is 26:(5~7):(65~69):1.

[0009] Furthermore, the front end of the crossarm is equipped with a binocular interface for connecting the microscope binocular head. The objective lens structure includes an objective lens turret and objective lenses that are connected to each other. The objective lenses can be selected from one or more of the following: 4x, 10x, 20x, 40x, and 100x objective lenses. The light-transmitting parts of the LED lamp, conical lens, variable aperture, and condenser glass are all circular and must be coaxial with the objective lenses.

[0010] Furthermore, the focusing base is equipped with focusing handwheels on both sides of the front, and a focusing assembly is installed inside. The bottom of the condenser lens is equipped with an up-and-down moving bracket.

[0011] Furthermore, the microscope is also equipped with a phase contrast structure, which includes an objective lens ring stop and a condenser lens ring stop. The objective lens ring stop is located in the middle of the objective lens, and the condenser lens ring stop is inserted into a socket in the middle of the upper shell. Both the objective lens ring stop and the condenser lens ring stop are concentric with the optical path of the microscope.

[0012] Furthermore, the LED light uses LED27 and is fixed to the bottom cover via an LED plum blossom substrate.

[0013] Furthermore, the conical lens has a cone-shaped structure with a concave center and an output angle range of 5~60°.

[0014] Furthermore, the visible structure is a display screen, which is connected to the horizontal arm via a pivot at the bottom and can be folded. Different folding angles are locked in place by setting limit bolts. The microscope body also contains a computer component, which is used to realize the observation, processing and other multimedia needs of the images presented by the microscope.

[0015] Furthermore, a pentagonal prism is mounted on the front end of the crossarm via a pentagonal prism mount, which is connected to a binocular interface via bolts. The camera assembly includes a camera and a camera adapter lens. The camera adapter lens is mounted on the front side of the camera and is connected to the pentagonal prism mount via a camera adapter lens mount. An extension tube is also provided at the rear end of the camera adapter lens mount.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: 1. The short-path digital microscope disclosed in this utility model, which optimizes the human-computer interaction process, has made significant optimizations to the light source structure, greatly shortening the optical path and reducing the number of optical glass, thereby reducing energy loss. This results in a significant increase in the brightness of the LED lamp at the same power. Thus, the technical solution of this utility model can achieve the brightness that existing biological microscopes can achieve at higher power while ensuring the observation effect.

[0017] 2. Due to the optimization of the overall structural components, the number of components in this utility model is relatively reduced, which greatly saves the cost of materials, processing, and assembly, and has strong application prospects.

[0018] 3. This utility model does not use a focusing lens, thus reducing the overall height of the microscope and the observation point. Therefore, a display screen is set at the top of the microscope, and the eye position is still at the operator's eye level, without having to tilt the head up. The position of the display screen has excellent human-computer interaction, thereby optimizing the human-computer interaction process.

[0019] 4. The structure of this utility model of a short-optical-path digital microscope designed to optimize the human-computer interaction process reduces the complexity of the light source structure, thus enabling the integration of computer, multimedia, and electronic display functions. It can be applied to intelligent control, and the display screen can be laid down and fixed for convenient transportation and storage.

[0020] 5. This utility model also incorporates a phase contrast structure, which enables the microscope to better observe transparent objects, allowing observation without staining the object and preserving its activity. Attached Figure Description

The visual structure is located at the upper end of the horizontal arm 10, the camera assembly 9 is located inside the horizontal arm 10, the upper and lower ends of the microscope body 12 are respectively connected to the rear end of the horizontal arm 10 and the rear end of the focusing base 16, the objective lens structure is located at the lower front end of the horizontal arm 10, and the light source structure 15 is located at the upper end of the focusing base 16, with the top connected to the platform assembly 14.

[0026] like Figure 2 As shown in (a), the light source structure 15 includes a condenser lens 21, a variable aperture 24, a conical lens 26, an LED lamp 27, and a housing. The housing includes an upper housing 23, a lower housing 20, and a bottom cover 29. The condenser lens 21 is fixed to the upper end of the upper housing 23 by a condenser lens 21 mount. The variable aperture 24 is inserted between the lower end of the upper housing 23 and the upper end of the lower housing 20. The conical lens 26 is placed below the variable aperture 24. The LED lamp 27 is placed below the conical lens 26, with its bottom end located above the bottom cover 29. The variable aperture 24 is equipped with an aperture lever 25, which extends out of the housing. The aperture lever 25 is used to adjust the variable aperture 24 to adapt to different observation needs.

[0027] In this embodiment, the ratio of the distance from the LED lamp 27 to the upper surface of the conical lens 26, the distance from the upper surface of the conical lens 26 to the upper surface of the variable aperture 24, the distance from the variable aperture 24 to the upper surface of the condenser glass 21, and the distance from the condenser glass 21 to the upper surface of the stage is 26:(5~7):(65~69):1.

[0028] In this embodiment, the front end of the crossarm 10 is provided with a binocular interface 3, which is used to connect the binocular head of the microscope. The objective lens structure includes an objective lens converter 111 and an objective lens 112 connected to each other.

[0030] In this embodiment, the short-optical-path digital microscope designed to optimize the human-computer interaction process is also equipped with a phase contrast structure, which includes an objective lens annular aperture 31 and a condenser lens annular aperture 32. The objective lens annular aperture 31 is located in the middle of the objective lens 112, and the condenser lens annular aperture 32 is inserted into a socket provided in the middle of the upper shell 23. Both the objective lens annular aperture 31 and the condenser lens annular aperture 32 are concentric with the optical path of the microscope.

[0031] In this embodiment, LED 27 is used as the LED lamp 27 and is fixed to the bottom cover 29 by LED plum blossom substrate 28. Conical lens 26 focuses the light emitted by LED 27, and then collimates and converges it by condenser glass 21. Due to the greatly shortened optical path and the reduction of glass components, the brightness loss is greatly reduced.

[0032] like Figure 2 As shown in (b) of the figure, in this embodiment, the conical lens 26 can be made of optical acrylic material, has a conical structure, is concave in the middle, and has a preferred light emission angle of 15°. In specific applications, the light emission angle ranges from 5° to 60°.

[0033] In this embodiment, the visible structure is a display screen 1, which is connected to the horizontal arm 10 via a pivot 2 at the bottom and can be folded. Different folding angles are locked in place by limiting bolts. A computer component 13 is also housed inside the microscope body 12. The computer component 13 is used for observing and processing images presented by the microscope and for other multimedia needs. Integrating the computer component 13 into the microscope body 12 facilitates use and transport.

[0034] It should be noted that the motherboard used in the computer component 13 of this embodiment is an industrial control computer motherboard. In actual applications, a general-purpose ITX board can also be used. The display screen 1 used in this embodiment is a 15.6-inch screen. In actual applications, a 21-inch display screen can also be used, or a screen can be customized as needed.

[0035] In this embodiment, the front end of the cross arm 10 is equipped with a pentagonal prism 5 via a pentagonal prism mount 4. The camera assembly 9 includes a camera and a camera adapter 6. The camera adapter 6 is installed on the front side of the camera. The camera adapter 6 is connected to the pentagonal prism mount 4 via a camera adapter mount 7. An extension tube 8 is also provided at the rear end of the camera adapter mount 7.

[0036] More specifically, the computer component 13 is threadedly connected to the lens body 12. A threaded connector built into the lens body 12 is screwed into the extension tube 8. The camera adapter mount 7 is threadedly connected to the pentagonal prism mount 4. The pentagonal prism 5 is connected to the pentagonal prism mount 4 via screws and adhesive bonding. The pentagonal prism mount 4 is bolted to the cross arm 10. The binocular interface 3 is bolted to the pentagonal prism mount 4. The camera adapter mount 7 is threadedly connected to the pentagonal prism mount 4. The camera component 9 is screwed into the extension tube 8. The extension tube 8 is threaded into the camera adapter mount 7. The cross arm 10 is bolted to the lens body 12. The focusing base 16 is bolted to the lens body 12. The platform assembly 14 and the light source structure 15 are bolted together. The light source structure 15 is connected to the upper and lower moving bracket 17 via a dovetail joint. The upper and lower moving bracket 17 is bolted to the rack 18.

[0037] The focusing assembly 19 is connected to the focusing base 16 by bolts, and the rack 18 meshes with the focusing assembly 19.

[0038] When the focusing handwheel 191 is rotated, the rack 18 moves up and down, thereby causing the upper and lower moving brackets 17, the carrying platform assembly 14 and the light source structure 15 to move up and down, thus completing the focusing action.

[0039] The specific control method of the short-path digital microscope for optimizing the human-computer interaction process in this embodiment includes the following steps: Step S1: Place the observation sample slide above the platform assembly; Step S2: Select a suitable objective lens 112, and rotate the objective lens turret 111 to rotate the objective lens 112 to the working position; Step S3: Rotate the focusing handwheel 19 to control the lifting and lowering of the transport platform assembly 14 so that the observed sample is located at the focal point; Step S4: Adjust the variable aperture 24 to the position corresponding to the 112x magnification of the objective lens, and adjust the brightness to a suitable level; Step S5: Adjust the screen position according to the image displayed on the screen 1, and control the screen scaling as needed to observe, process and apply the image to other multimedia scenarios.

[0040] It should be noted that in step S4, the brightness adjustment can be achieved using existing technologies such as a physical brightness adjustment knob or other physical adjustment structures, or it can be achieved by setting the corresponding brightness adjustment function through the computer component 13.

[0041] Example of effect 1 The image was obtained by using the short-path digital microscope described in Example 1, which is designed to optimize the human-computer interaction process. Figure 4 As shown in (a) above, a comparative observation was also performed using a conventional biological microscope, and the images are as follows. Figure 4 As shown in (b) of the diagram.

[0042] The LED lamp parameters used in this invention's short-path digital microscope, designed to optimize the human-computer interaction process, are: 2.65V, 0.016A, 0.04W. The LED lamp parameters used in a conventional biological microscope are: 2.72V, 0.137A, 0.37W.

[0043] It is evident that the short-path digital microscope of this invention, designed to optimize the human-computer interaction process, can still produce clear images while maintaining the required brightness under low energy consumption conditions.

[0044] like Figure 5 As shown, the optical path design principle of the short-path digital microscope for optimizing the human-computer interaction process disclosed in this utility model is as follows: Light emitted from LED 27 passes through the conical lens 26, then is collimated and focused onto the object platform 14 by the condenser lens 21. Next, after passing through the object, the light is refracted by the objective lens 112, restored by the tube diameter 30, and then split and redirected by the pentagonal prism 5. One beam is corrected by the camera adapter lens 6 and falls onto the camera assembly 9, while the other beam leads to the binocular interface 3. This microscope, because it allows for the simultaneous installation of binocular lenses at the binocular interface 3, enables multi-mode observation.

[0045] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
