Description

Technical Field

[0001] This application relates to the field of microscopy technology, and more particularly to a microscope. Background Technology

[0002] During the use of a microscope, the size of the stage required often varies depending on the object being observed. When the stage needs to be changed, the lens and stage positions often need to be adjusted manually, which is time-consuming, labor-intensive, and often requires multiple calibrations. Utility Model Content

[0003] This application provides a microscope to solve the problem that manually adjusting the lens and stage positions is difficult to do accurately and is time-consuming and labor-intensive when changing the stage.

[0004] In a first aspect, this application provides a microscope, including a base, a lens holder, and a lens, wherein at least two stage mounting holes are fixedly provided on the base, and the at least two stage mounting holes are at different distances from the lens holder, for mounting stages of different specifications so that the stages are perpendicular to the optical axis of the lens.

[0005] In this embodiment, at least two stage mounting holes are fixedly provided on the microscope base, and the distance between the different stage mounting holes and the lens support is different, which facilitates the quick installation of stages of different specifications. In addition, since the position of the stage mounting holes is fixed, the stage can be directly installed by aligning the matching stage mounting holes according to the stage specifications, so that the lens optical axis is perpendicular to the stage, without the need for multiple calibrations, thereby improving the efficiency of microscope use and saving overall time.

[0006] Optionally, the stage includes at least one motorized stage, with mounting holes for snapping the motorized stage onto the base. Based on this, the microscope provided in this embodiment is compatible with motorized stages. The high-precision planar displacement control of the motorized stage provides high observation accuracy. Furthermore, the snap-fit ​​method for fixing the motorized stage allows for its replacement, enabling the selection of a stage specification suitable for the observation target according to requirements.

[0007] Optionally, the at least two platform mounting holes include a first platform mounting hole and a second platform mounting hole; the first platform mounting hole includes: a first reference surface vertically nested on the base, a second reference surface vertically engaged with the first reference surface, and a base first interface located in the middle of the second reference surface; the second platform mounting hole includes: a third reference surface vertically nested on the base, a fourth reference surface vertically engaged with the third reference surface, and a base second interface located in the middle of the fourth reference surface.

[0008] Based on this, the mounting holes on the platform can mate with the platform mounting section on the platform to achieve a snap-fit ​​fixation of the platform on the base. The first interface and the second interface of the base can be electrically connected to the platform interface of the electric platform to provide power for the electric platform's drive. This allows the electric platform to be used immediately after snapping into the base, without the need for additional wiring and power supply to the electric platform, thus facilitating its use.

[0009] Optionally, the electric stage includes a stage mounting part, which includes: a stage interface that matches the first interface or the second interface of the base; a first reference surface of the stage that fits the shape of the first reference surface or the second reference surface; a second reference surface of the stage that is perpendicularly connected to the first reference surface of the stage; and a third reference surface of the stage where the stage interface is located, wherein the third reference surface of the stage is parallel to the second reference surface of the stage.

[0010] Based on this, the stage mounting hole can mate with the stage mounting part on the stage to achieve a snap-fit ​​fixation of the stage on the base. Taking the stage mounting part located in the first stage mounting hole as an example, the first reference surface of the stage fits the shape of the first reference surface, allowing the stage mounting part to extend vertically into the base. Furthermore, the second reference surface of the stage is perpendicularly engaged with the first reference surface, so that after the stage mounting part extends vertically into the base, the second reference surface of the stage can fit against the second reference surface of the base, providing vertical upward support for the stage, ensuring stable installation, and ensuring that the upper surface of the stage is perpendicular to the lens optical axis. This ensures that when the upper surface of the stage is moved, the microscope observation area on the upper surface of the stage is always at the focal point of the lens, avoiding frequent focusing during stage movement and making the microscope more convenient to use. Furthermore, the third reference plane of the platform where the platform interface is located is set parallel to the second reference plane of the platform. When the platform interface is connected to the first interface of the base, the third reference plane of the platform is also parallel to the second reference plane of the base. This can avoid interference between the platform interface and the second reference plane of the base during connection, thereby ensuring the reliability of the connection between the platform interface and the first interface of the base.

[0011] Optionally, the top of the first reference surface of the first platform mounting hole has at least one platform positioning hole, and the top of the third reference surface of the second platform mounting hole has at least one platform positioning hole; a platform positioning pin is formed on the first reference surface of the platform; the platform mounting part is used to install the electric platform into the first platform mounting hole or the second platform mounting hole, and to engage the platform positioning pin in the platform positioning hole so that the electric platform is fully constrained and fixed to the base at a specified height, and the platform interface is assembled and engaged with the first interface or the second interface of the base by stepped screws.

[0012] Based on this, by setting platform positioning holes in the platform mounting holes, the platform can be quickly positioned, reducing the time required for manual adjustment of the platform interface and base interface when changing platforms, thus enabling rapid platform assembly. Furthermore, after the platform positioning pin is engaged with the platform positioning hole, the platform can be fully constrained and fixed to the base at a specified height, ensuring the stability of the platform installation. In addition, the platform interface and the first or second interface of the base are assembled and engaged using stepped screws, allowing for a certain amount of movement of the platform interface and preventing over-constraint, thereby ensuring that the platform interface can connect to the first or second interface of the base.

[0013] Optionally, the top chamfer of the platform positioning hole is flared to guide the platform positioning pin's angle when it is engaged or disengaged. This flared chamfer eliminates the need for precise alignment of the platform positioning pin with the positioning hole during installation; the chamfer facilitates easy insertion of the pin, thus improving installation efficiency.

[0014] Optionally, the microscope is an electron microscope, which also includes a motherboard, and a first or second base interface is electrically connected to the motherboard. The mounting orientation of the first and second base interfaces is designed to prevent incorrect mounting.

[0015] Based on this, either the first or second interface of the base is electrically connected to the motherboard, allowing power to be supplied to the motorized stage mounted on it. This enables the motorized stage to be simply snapped into place on the base for immediate use, eliminating the need for additional wiring and power supply to the stage, thus simplifying its operation. Furthermore, the microscope is compatible with various sizes of motorized stages. Since different motorized stages have different operating parameters, the correct mounting orientation of the first and second interfaces of the base ensures that different sizes of motorized stages are correctly installed in their corresponding mounting holes, thereby guaranteeing proper operation of the motorized stage.

[0016] Optionally, after the motherboard determines that there is a motorized stage electrically connected to the base first interface or base second interface through the stage interface, it identifies the specifications of the motorized stage, obtains the corresponding stage travel according to the identified specifications, runs the stage according to the stage travel, and records the coordinates of the center of the field of view of the lens; after the motherboard determines that there is no motorized stage electrically connected to any of the stage mounting holes, it starts the manual stage mode.

[0017] Based on this, the microscope provided in this application is compatible with both manual and electric drive stages. Furthermore, for electric stages, it can automatically identify different electric stage specifications and drive the stage according to the corresponding stage stroke based on the identified electric stage specifications, thereby ensuring that electric stages of different specifications can be automatically identified and driven normally, achieving compatibility with multiple stages.

[0018] Optionally, the motorized stage is available in two sizes: a small stage (40*40mm) and a large stage (200*100mm). Based on this, the appropriate stage size can be selected according to the requirements of the observation target. Specifically, for observation targets requiring high precision, the 40*40mm small stage is selected. This small stage has a shorter travel distance than the large stage, resulting in higher motion accuracy. Using the small stage can meet the requirements for high-precision observation. For observation targets requiring lower precision, the 200*100mm large stage can be used. This large stage has a longer travel distance than the small stage, allowing for rapid adjustment of the microscope's observation area, thus meeting the requirements for rapid detection.

[0019] Optionally, the positions of the platform positioning holes of the first platform mounting hole 111 and the second platform mounting hole 112 are designed to prevent mistaken positioning.

[0020] If the motherboard determines that there is an electric motor connection in any of the stage mounting holes, it identifies the specifications of the electric motor, obtains the corresponding stage travel according to the identified specifications, runs the electric motor according to the stage travel, and records the coordinates of the center of the field of view of the lens.

[0021] If the motherboard determines that there is no motorized platform connection in any of the platform mounting holes, then the manual platform mode will be activated.

[0022] Based on this, the microscope base provided in this application is fixedly provided with at least two stage mounting holes, which facilitates the quick installation of stages of different specifications and is compatible with both manual and electric drive stages. For electric stages, the microscope provided in this application can automatically identify different electric stage specifications and drive the stage according to the corresponding stage stroke based on the identified specifications, thereby ensuring that electric stages of different specifications can be automatically identified and driven normally, achieving compatibility with multiple stages.

Detailed Implementation

[0033] The present application will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present application. Any structural or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present application.

[0034] The purpose of this application is to solve the problem that manually adjusting the position of the lens 13 and the position of the stage is difficult to do accurately and is time-consuming and labor-intensive when changing the stage of a microscope.

[0035] Based on the above objectives, in a first aspect, this application provides a microscope. The microscope includes: a base 11, a lens support 12, and a lens 13, wherein at least two stage mounting holes are fixedly provided on the base 11, and the at least two stage mounting holes are at different distances from the lens support 12, for mounting stages of different specifications, so that the stage is perpendicular to the optical axis of the lens 13.

[0036] like Figure 1As shown, it illustrates a schematic diagram of a microscope provided in one embodiment of this application. Figure 1 The document defines the orientation relationships of the microscope in terms of up / down, front / back, and left / right. To facilitate the explanation of the microscope provided in the embodiments of this application, it is assumed that the microscope is placed on a horizontal plane. In this case, the up / down direction of the microscope is perpendicular to the horizontal plane, and the up / down, left / right, and front / back directions of the microscope are mutually perpendicular to each other.

[0037] like Figure 1 As shown, the microscope's lens holder 12 is connected to the base 11. The lens holder 12 includes a lens adjustment mechanism for mounting a lens 13. The optical axis of the lens 13 is perpendicular to the horizontal plane, and the lens adjustment mechanism can adjust the height of the lens 13 vertically. Figure 1 and Figure 2 The lens adjustment mechanism includes a lens moving guide groove and a lens guide pin 121. The lens guide pin 121 is disposed in the lens moving guide groove, which is arranged in the left and right direction, so that the lens can be adjusted in the left and right direction to adjust the lens optical axis and align the lens optical axis with the 0 position of the stage.

[0038] like Figure 1 As shown, two stage mounting holes are provided on the base 11. The two stage mounting holes are configured such that after the stage is installed on the base 11 through the stage mounting holes, the upper surface of the stage is perpendicular to the optical axis of the lens 13. This eliminates the need for multiple calibrations after the stage is installed, thereby improving the efficiency of the microscope and saving overall time.

[0039] like Figure 1 As shown, in this embodiment, the two stage mounting holes are arranged along the left-right direction of the microscope, which facilitates the rapid installation of stages of different specifications. In another optional implementation, the two stage mounting holes can be arranged along a first direction, which forms a certain angle with the left-right direction of the microscope. The angle between the first direction and the left-right direction of the microscope is less than 90°. In this way, the distance between the different stage mounting holes and the lens support 12 can also be different, facilitating the rapid installation of stages of different specifications.

[0040] In another alternative implementation, the number of stage mounting holes can be three or more, allowing the microscope to be compatible with a wider range of stage sizes.

[0041] As an optional implementation, the stage includes at least one motorized stage 14, with stage mounting holes that snap-fit ​​the motorized stage 14 onto the base 11. Specifically, the stage mounting holes on the base 11 match the stage mounting portion 141 at the bottom of the motorized stage 14, allowing the motorized stage 14 to be positioned on the base 11, achieving compatibility between the microscope and the motorized stage 14. Compared to a manually controlled stage, the motorized stage 14 provides higher horizontal plane displacement control accuracy, enabling precise positioning of the target observation area, facilitating microscope observation, and improving observation efficiency. Furthermore, the snap-fit ​​fixing of the motorized stage 14 allows for its replacement, enabling the selection of a stage specification suitable for the observation target according to requirements.

[0042] As an optional implementation, the at least two platform mounting holes include a first platform mounting hole 111 and a second platform mounting hole 112; the first platform mounting hole 111 includes: a first reference surface 101 vertically nested on the base 11, a second reference surface 102 vertically engaged with the first reference surface 101, and a base first interface 1111 located in the middle of the second reference surface 102; the second platform mounting hole 112 includes: a third reference surface 103 vertically nested on the base 11, a fourth reference surface 104 vertically engaged with the third reference surface 103, and a base second interface 1121 located in the middle of the fourth reference surface 104.

[0043] Specifically, such as Figure 3 The diagram shows a schematic of the first stage mounting hole 111 and the second stage mounting hole 112. For the first stage mounting hole 111, the first reference surface 101 is cylindrical, with its axis perpendicular to the horizontal plane, allowing it to be vertically nested on the base 11. The second reference surface 102 is located on top of the first reference surface 101 and is perpendicularly engaged with it. Based on this, the stage mounting hole can cooperate with the stage mounting portion 141 on the stage (the specific cooperation method will be described later) to achieve a snap-fit ​​fixation of the stage on the base 11. This also facilitates the installation of the stage on the base 11, ensuring that the upper surface of the stage is perpendicular to the optical axis of the lens 13. This eliminates the need for multiple refocusing adjustments during stage translation, improving the efficiency of the microscope.

[0044] Furthermore, the base first interface 1111 is located at the bottom of the first platform mounting hole 111 and is surrounded by the first reference surface 101. For ease of explanation, the projection of the base first interface 1111 along the vertical direction onto the second reference surface 102 is defined as the first projection, and the projection of the first reference surface 101 along the vertical direction onto the second reference surface 102 is defined as the second projection. The first projection is located in the central region of the second projection. Compared to the method where the base first interface 1111 is eccentrically located at the bottom of the first platform mounting hole 111, the method provided in this application, which places the base first interface 1111 in the central region of the bottom of the first platform mounting hole 111, facilitates the electrical connection between the platform interface 1411 and the base first interface 1111, thereby improving the assembly efficiency of the platform.

[0045] The third reference surface 103, the fourth reference surface 104, and the second interface 1121 of the base are basically the same as those of the first platform mounting hole 111, and will not be described in detail here.

[0046] As an optional implementation, the electric stage 14 includes a stage mounting part 141, which includes: a stage interface 1411 that matches the base first interface 1111 or the base second interface 1121; a stage first reference surface 201 that fits the shape of the first reference surface 101 or the second reference surface 102; a stage second reference surface 202 that is perpendicularly engaged with the stage first reference surface 201; and a stage third reference surface 203 where the stage interface 1411 is located, wherein the stage third reference surface 203 is parallel to the stage second reference surface 202.

[0047] Specifically, such as Figure 4The diagram shows a schematic of a platform mounting portion 141 provided in one embodiment of this application. Taking the platform mounting portion 141 matching the first platform mounting hole 111 as an example, the first reference surface 201 of the platform is in the shape of a cylindrical outer wall, and the outer diameter of the cylinder is substantially equal to the inner diameter of the first reference surface 101, so that the shape of the first reference surface 101 fits the first reference surface 201 of the platform. An annular protrusion is formed on the top of the first reference surface 101, and the lower surface of the annular protrusion (referring to the state when the platform mounting portion 141 is combined with the platform mounting hole) serves as the second reference surface 202 of the platform, which is perpendicularly engaged with the first reference surface 201 of the platform. When the stage mounting part 141 mates with the first stage mounting hole 111, the first reference surface 201 of the stage mounting part 141 extends into the first stage mounting hole 111 and fits against the first reference surface 201. After the first reference surface 201 extends to a specified depth, the second reference surface 202 of the stage will abut against the second reference surface 102 of the base 11. Since the first reference surface 101 of the base 11 is vertically nested in the base 11, it can be ensured that after the stage is installed, the upper surface of the stage is perpendicular to the optical axis of the lens 13. This ensures that when the upper surface of the stage is translated, the microscope observation area on the upper surface of the stage is always at the focal point of the lens 13, avoiding frequent focusing when the stage is moved, and making the microscope more convenient to use.

[0048] The cross section at the end of the platform interface 1411 is defined as the third reference plane 203 of the platform where the platform interface 1411 is located. The third reference plane 203 of the platform is set parallel to the second reference plane 202 of the platform. In this way, when the platform interface 1411 is connected to the first interface 1111 of the base, the third reference plane 203 of the platform is also parallel to the second reference plane 102 of the base 11, thereby avoiding interference between the platform interface 1411 and the second reference plane 102 of the base 11 during the connection, thus ensuring the reliability of the connection between the platform interface 1411 and the first interface 1111 of the base.

[0049] As an optional implementation, the top of the first reference surface 101 of the first platform mounting hole 111 has at least one platform positioning hole 113, and the top of the third reference surface 103 of the second platform mounting hole 112 has at least one platform positioning hole 113; a platform positioning pin 1412 is formed on the first reference surface 201 of the platform; the platform mounting part 141 is used to install the electric platform 14 into the first platform mounting hole 111 or the second platform mounting hole 112, and to engage the platform positioning pin 1412 into the platform positioning hole 113, so that the electric platform 14 is fully constrained and fixed to the base 11 at a specified height.

[0050] Specifically, in combination Figure 3 and Figure 4Taking the first platform mounting hole 111 as an example (the structure of the second platform mounting hole 112 is similar to that of the first platform mounting hole 111, and will not be described in detail here), as follows... Figure 3 As shown, the top of the first reference surface 101 of the first stage mounting hole 111 has at least one stage positioning hole 113. Figure 4 As shown, a platform positioning pin 1412 is formed on the first reference surface 201 of the platform. Through the engagement of the platform positioning hole 113 of the base 11 with the platform positioning pin 1412, rapid positioning of the platform can be achieved, reducing the time required for manual adjustment of the interface alignment between the platform interface 1411 and the base 11 interface during platform installation, thus enabling rapid assembly of the platform. Furthermore, after the platform positioning pin 1412 is engaged with the platform positioning hole 113, the platform can be fully constrained and fixed to the base 11 at a specified height, ensuring the stability of the platform installation.

[0051] As an optional implementation, the mounting orientation of the base first interface 1111 and the base second interface 1121 is designed to prevent incorrect mounting.

[0052] Optionally, the positions of the platform positioning holes of the first platform mounting hole and the second platform mounting hole are designed to prevent mistaken identification.

[0053] Specifically, in combination Figure 3 and Figure 4 In this embodiment, the first interface 1111 of the base and the second interface 1121 of the base are in a T-shape, such as... Figure 3 As shown, the base first interface 1111 and the base second interface 1121 each include a first portion extending in the front-back direction and a second portion extending in the left-right direction, wherein the second portion intersects with the middle area of ​​the first portion. For the base first interface 1111, the second portion points towards the platform positioning hole 113, while for the base second interface 1121, the second portion faces away from the platform positioning hole 113. Due to the constraint of the platform positioning hole 113 and the platform positioning pin 1412, the platform can only be inserted into the platform positioning hole 113 in a fixed direction. For example, if the direction between the platform interface 1411 and the base first interface 1111 is opposite, the platform cannot be installed on the base first interface 1111; if the direction between the platform interface 1411 and the base second interface 1121 is opposite, the platform cannot be installed on the base second interface 1121, thus achieving the effect of foolproof design and avoiding incorrect assembly of the platform. In another alternative implementation, the second parts of the base first interface 1111 and the base second interface 1121 point to different directions, which can also serve as a foolproof setting.

[0054] As an optional implementation method, such as Figure 5As shown, the top chamfer of the platform positioning hole 113 is flared, which guides the platform positioning pin 1412 to adjust its platform angle when it is engaged or disengaged from the platform positioning hole 113. Therefore, the flared chamfer of the top of the platform positioning hole 113 allows the platform positioning pin 1412 to be easily aligned with the platform positioning hole 113 during platform installation, thus improving the platform installation efficiency.

[0055] As an optional implementation, the platform interface 1411 is assembled and snapped with the base first interface 1111 or the base second interface 1121 by step screws 1411a.

[0056] Specifically, in combination Figure 6 , Figure 7 and Figure 8 The platform interface 1411 includes a platform interface 1411 mounting part for mounting a stepped screw 1411a. The stepped screw 1411a passes through the platform interface 1411 mounting part and is threaded to the bottom of the platform. The thickness of the platform interface 1411 mounting part is less than the screw section of the stepped screw 1411a, thus allowing the platform interface 1411 to have a certain amount of movement. Since the platform and the base 11 are fully constrained and fixed, in this embodiment, the platform interface 1411 is mounted with a stepped screw 1411a, allowing the platform interface 1411 to have a certain amount of movement, avoiding over-constraint, thereby ensuring that the platform interface 1411 can be connected to the first interface 1111 or the second interface 1121 of the base. Figure 9 The diagram shown illustrates a schematic of the microscope base after the stage has been assembled.

[0057] As an optional implementation, the microscope provided in this embodiment is an electron microscope. The electron microscope also includes a motherboard, and the base first interface 1111 or the base second interface 1121 is electrically connected to the motherboard. Based on this, the base first interface 1111 or the base second interface 1121 is electrically connected to the motherboard, so that the electric stage 14 mounted on it can be powered through the base first interface 1111 or the base second interface 1121. This allows the electric stage 14 to be used simply by snapping it onto the base 11 without the need for additional wiring to power the electric stage 14, thus facilitating its use.

[0058] As an optional implementation, after the motherboard determines that there is an electric stage 14 electrically connected to the base first interface 1111 or the base second interface 1121 through the stage interface 1411, it identifies the specifications of the electric stage 14, obtains the corresponding stage travel according to the identified specifications, and runs the stage according to the stage travel; after the motherboard determines that there is no electric stage 14 electrically connected to any of the stage mounting holes, it starts the manual stage mode.

[0059] Specifically, assuming the first interface 1111 of the base is closer to the lens bracket 12 than the second interface 1121 of the base, if the motherboard determines that a motorized stage 14 is electrically connected to the first interface 1111 of the base via stage interface 1411, considering the distance limitation between the base interface 1111 and the lens bracket 12, the motherboard drives the motorized stage with a smaller stroke to avoid interference between the motorized stage and the lens bracket 12. If the motherboard determines that a motorized stage 14 is electrically connected to the second interface 1121 of the base via stage interface 1411, since the second interface 1121 of the base is farther from the lens bracket 12, the motherboard can drive the motorized stage with a relatively larger stroke. For example, when driving the motorized stage, it can move simultaneously or separately on the X and Y axes in a horizontal position according to the host's instructions to reach the position specified by the host. Each time the motorized stage reaches a position, the coordinates of the lens's field of view center are recorded.

[0060] For example, when driving the motorized stage, the motorized stage can be translated in a zigzag or S-shaped pattern on the horizontal plane, so that the microscope can observe different observation areas of the stage.

[0061] If the motherboard determines that there is no electric connection to the motorized platform 14 in any of the platform mounting holes, it will activate the manual platform mode and move the platform manually.

[0062] Based on this, the microscope provided in this application is compatible with both manual and electric drive stages. Furthermore, for the electric stage 14, it can automatically identify different specifications of the electric stage 14 and drive the stage according to the corresponding stage stroke based on the identified specifications of the electric stage 14, thereby ensuring that electric stages 14 of different specifications can be automatically identified and driven normally, thus achieving compatibility with multiple stages.

[0063] As an optional implementation, the motorized stage 14 is available in two sizes: a small stage of 40*40mm and a large stage of 200*100mm. Based on this, the appropriate stage size can be selected according to the requirements of the observation target. Specifically, for observation targets requiring high precision, the 40*40mm small stage is selected. The small stage has a shorter travel distance than the large stage, resulting in higher motion precision. Using the small stage can meet the high-precision observation requirements. For observation targets requiring lower precision, the 200*100mm large stage can be used. The large stage has a longer travel distance than the small stage, allowing for rapid adjustment of the microscope's observation area, thus meeting the requirements for rapid detection.

[0064] The microscope in this embodiment can be an electron microscope system, which includes a motherboard, a base 11, and a motorized stage 14. The base 11 is provided with at least two stage mounting holes, and the motherboard determines whether the motorized stage 14 is electrically connected in at least two stage mounting holes.

[0065] If the motherboard determines that there is an electric motor stage 14 electrically connected in any stage mounting hole, it identifies the specifications of the electric motor stage 14, obtains the corresponding stage travel according to the identified specifications, and runs the electric motor stage 14 according to the stage travel.

[0066] If the motherboard determines that there is no electric connection to the motorized stage 14 in any of the stage mounting holes, then the manual stage mode will be activated.

[0067] Specifically, assuming that the first stage mounting hole 111 is closer to the lens bracket 12 than the second stage mounting hole 112, if the motherboard determines that there is an electric stage 14 electrically connected to the first stage mounting hole 111, considering the distance limitation between the base 11 interface and the lens bracket 12, the motherboard drives the electric stage with a smaller stroke to avoid interference between the electric stage and the lens bracket 12; if the motherboard determines that there is an electric stage 14 electrically connected to the second stage mounting hole 112, since the second stage mounting hole 112 is farther from the lens bracket 12, the motherboard can drive the electric stage with a relatively larger stroke.

[0068] For example, the motorized stage can move horizontally, simultaneously or separately along the X and Y axes, according to the instructions of the host, to reach the position specified by the host. Each time the motorized stage reaches a position, the coordinates of the lens's field of view center are recorded.

[0069] For example, when driving the motorized stage, the motorized stage can be translated in a zigzag or S-shaped pattern on the horizontal plane, so that the microscope can observe different observation areas of the stage.

[0070] Based on this, the microscope base 11 provided in this application is fixedly provided with at least two stage mounting holes, which facilitates the quick installation of stages of different specifications and is compatible with both manual and electric drive stages. Regarding the electric stage 14, the microscope provided in this application can automatically identify different specifications of the electric stage 14 and drive the stage according to the corresponding stage stroke based on the identified specifications, thereby ensuring that electric stages 14 of different specifications can be automatically identified and driven normally, achieving compatibility with multiple stages.
