Description

TECHNICAL FIELD

[0001] The utility model relates to microscopic observation device technical field especially, a kind of light-transmissible workbench for microscopic observation. BACKGROUND

[0002] In the field of microscopic observation, workbench as the key component of bearing and accurately moving the sample to be observed, its design is crucial to improve observation efficiency and accuracy. Traditional microscopic observation workbench is usually designed with X, Y direction movement function, so as to facilitate researchers to observe and analyze the sample in detail. However, these workbenches are often only suitable for observation tasks under specific lighting conditions.

[0003] Patent No. ZL201720844733.2, entitled "X, Y direction moving workbench for microscopic observation sample", is a patent once applied by the applicant, aiming at improving the flexibility and accuracy of microscopic observation. The workbench can control the movement of X and Y directions by rotating two knobs of the moving workbench, and is equipped with scales for precise positioning. These features enable it to perform outstandingly under oblique illumination observation conditions. As a common microscopic observation lighting method, oblique illumination can enhance the presentation of sample surface texture and details by oblique light, and is widely used in specific research fields.

[0004] However, the design of this patent workbench also has certain limitations. Specifically, it is only suitable for objects that can be clearly imaged by oblique illumination. For another class of samples that need to be clearly observed by transmitted light illumination, such as biological sections and thin film materials, this workbench cannot meet the requirements. Transmitted light illumination refers to the way of illuminating by light passing through the sample, which requires the workbench to have a channel for light to penetrate the sample, and the workbench itself cannot block or interfere with the propagation of light. However, the workbench with patent No. ZL201720844733.2 is not designed for this requirement, so its application is limited when facing observation tasks that require transmitted light illumination. UTILITY MODEL CONTENT

[0005] The utility model aims to provide a light-transmissible workbench for microscopic observation, which can solve the problem that existing technology cannot be used to observe samples that need to be clearly observed by transmitted light illumination.

[0006] In order to solve the above problems, the utility model adopts the technical scheme: this light -transmitting work table for microscopic observation, including the object table panel, sliding plate and bottom plate, three from top to bottom are installed in proper order, the object table panel middle part has the window, the window is placed with the transparent object of the window shape matching, the bottom plate middle part has a through -hole for light -transmitting, the sliding plate middle part has a through long slot on the through -hole along Y direction, the width R of the long slot is equal to the inner diameter r of the through -hole.

[0007] More specific technical solutions in the above technical solutions can also be: the two sides on the sliding plate top surface are respectively equipped with upper guide rail seat, and the object table panel is installed in the upper guide rail seat; the two ends on the sliding plate bottom surface are respectively equipped with lower guide rail seat, and the two ends of the bottom plate are installed in the lower guide rail seat.

[0008] Further, an X-direction scale mark segment is arranged on the side of one of the upper guide rail seats adjacent to the object table panel, and a short scale mark segment is arranged on the side of the object table panel adjacent to the upper guide rail seat provided with the X-direction scale mark segment.

[0009] Further, a Y-direction scale mark segment is arranged on one side of the sliding plate along the Y direction, a Y-direction through slot parallel to the Y-direction scale mark segment is arranged on the inner side of the Y-direction scale mark segment of the sliding plate, the length of the Y-direction through slot is equal to the length of the Y-direction scale mark segment, a scale block is slidably arranged in the Y-direction through slot, and the bottom of the scale block is connected to the bottom plate.

[0010] Further, a pair of pressing plate clamps is installed on the opposite sides of the object table panel close to the edges of the window, and the movable ends of the pair of pressing plate clamps extend to the top surface of the long slot.

[0011] Further, the transparent object is one of glass, transparent acrylic plate or transparent silica gel plate.

[0012] Further, the left and right movement of the object table panel in the X direction is controlled by an X-direction knob installed on the upper guide rail seat, and the forward and backward movement of the sliding plate in the Y direction is controlled by a Y-direction knob installed on the upper guide rail seat.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. Enhanced light transmittance: due to the window in the middle of the object carrier panel, which is covered by a transparent object, and the through hole in the middle of the bottom plate due to the light transmission, and the long slot on the sliding plate, by setting the window, through hole and long slot of specific position and size, the channel for light to penetrate the sample is realized, which can significantly improve the light transmittance of the workbench surface, so that the observation object under the microscope can obtain more sufficient and more uniform natural light or artificial lighting, thereby improving the observation clarity and detail resolution.

[0015] 2. Improve the accuracy and readability of the scale: on the basis of maintaining the original scale mark segment, the design of the window and the through hole can cleverly avoid the scale mark, ensuring that the scale is clear and visible under any lighting conditions without obstruction, which is crucial for microscopic operations that require accurate measurement and positioning, such as cell culture, micro-nano processing and other fields.

[0016] 3. Enhance multi-functionality and compatibility: the newly added window, through hole and long slot design makes the workbench able to adapt to more types of microscope accessories and experimental devices, such as transmission light illumination system, fluorescence excitation / detection module, etc., thereby widening the application scenarios of the workbench, making it not only limited to traditional microscopic observation, but also meeting the advanced research needs of fluorescence imaging, dynamic monitoring of living cells, etc.

[0017] 4. Simplify maintenance and upgrade: this design facilitates users to clean, maintain or upgrade components such as replacing light source modules, adjusting optical path, etc. without disassembling the entire workbench, reducing maintenance costs and improving the long-term reliability and service life of the equipment.
