Description

Technical Field

[0001] The present invention relates to the technical field of optical microscopes, and in particular to an additional optical device suitable for being attached to an optical microscope and a microscope assembly comprising the microscope and the additional optical device. Background Art

[0002] An imaging beam path and an illumination beam path are usually formed in a microscope. The microscope can adjust the imaging path so that different areas or different objects can be clearly observed with variable resolution and variable distance. Usually, the resolution and / or distance of the microscope can only be changed within a specific range. The expansion and / or change of this specific range makes the application of the microscope more flexible and diverse.

[0003] The illumination beam path usually overlaps with the imaging beam path to optimally direct the light to the observation area. Some additional optical devices attached to the microscope have been developed in the prior art. However, these additional optical devices are usually constructed to act on a single beam path so as to act primarily on the imaging path and only secondarily on the illumination beam path. There are also some microscope designs that change the position and direction of the illumination and can even include several illumination devices. Therefore, when the resolution of the microscope is changed using additional optical devices, the illumination will also change, resulting in a decrease in the illumination quality of the observation area and even shadows in the observation area. Summary of the invention

[0004] The object of the present invention is to solve at least one of the above problems and defects in the prior art as well as other technical problems.

[0005] In one aspect, the present invention provides an additional optical device suitable for attachment to a microscope, the additional optical device comprising an imaging optical device and an illumination optical device, wherein the imaging optical device is suitable for being placed in an imaging path of the microscope, and the illumination optical device is suitable for being placed in an illumination path of the microscope, wherein the imaging path and the illumination path are separated, and wherein the illumination optical device is configured to match the imaging optical device so as to act on the illumination path to project light into the field of view of the microscope.

[0006] In this solution, the imaging path and the illumination path are separated, and the illumination optics of the additional optical device are matched with the imaging optics so that the illumination is adapted to the changed observation area, i.e., the adjusted field of view of the microscope, to ensure sufficient illumination of the changed observation area.

[0017] According to an exemplary solution, the additional optical device further includes a positioning member, which passes through the second wall, passes through the connecting portion and is fixed to the first wall, and is particularly screwed into a threaded hole formed on the first wall. The positioning member in this example fixes the connecting portion in a direction perpendicular to the insertion direction of the connecting portion, thereby ensuring the positioning accuracy of the connecting portion in the receiving seat.

[0018] According to an exemplary embodiment, the accommodating seat is also formed with a locking hole extending from its outer surface to its internal accommodating space and a locking component arranged through the locking hole, and a locking mating portion is arranged on the insertion end of the connecting part, and the locking component is suitable for cooperating with the locking mating portion to lock or release the connecting part.

[0020] According to an exemplary solution, a guide surface is further formed on the locking fitting portion, and the guide surface guides the stopper to engage with the stop surface during the process of inserting the connecting portion into the accommodating seat.

[0021] In the above examples, a locking component is used, so that the initial connection positioning of the connecting part in the receiving seat can be achieved during the process of inserting the connecting part into the receiving seat, and the connection can be conveniently released by a simple operation of pressing the locking member.

[0022] According to an exemplary solution, the additional optical device further comprises an electrical connection interface connected to the microscope. The electrical connection interface can realize power supply and information transmission between the additional optical device and the microscope. The information is, for example, information about the type, performance parameters, settings, etc. of the additional optical device, or information about the type of the microscope, settings of the imaging path and / or the illumination path, settings of the illumination source, etc.

[0023] According to an exemplary solution, the additional optical device further comprises a control device, and the control device is electrically connected to the microscope via the electrical connection interface. This structure facilitates automatic control of microscope components, especially for a microscope using a zoom lens and an additional optical device using a zoom lens, exchanging current setting information about the microscope or the additional optical device facilitates corresponding control of the zoom lens.

[0024] According to an exemplary solution, the additional optical device also includes a control device and is capable of wireless communication with the microscope. The control device is, for example, a chip on which a wireless communication module is integrated. This communication method facilitates the transmission of information and simplifies the mechanical structure of the microscope.

[0025] According to an exemplary solution, the additional optical device further comprises a sensor disposed on the receiving seat or on the connecting portion to send a signal when the connecting portion is inserted into the receiving seat. This solution makes it possible to know that the optical main body of the additional optical device is in place in the optical path of the microscope and that the additional optical device is ready.

[0026] According to an exemplary solution, the sensor is disposed in a receiving seat, and an electrical connection interface is disposed on the receiving seat, wherein the electrical connection interface electrically connects the sensor to the microscope.

[0028] According to an exemplary embodiment, the additional optical device includes a fixing member and an optical main body portion slidably connected to the fixing member, wherein the fixing member is suitable for being fixed to the housing; wherein the illumination optical device and the imaging optical device are arranged in the optical main body portion, and the optical main body portion can slide to a working position and can slide out from the working position, wherein the illumination optical device and the imaging optical device are respectively placed in the illumination path and the imaging path.

[0029] In this solution, under normal conditions, the optical main body is suspended in a standby position outside the illumination optical path and the imaging optical path by a fixing member. This structure enables the optical main body of the additional optical device to be quickly moved in and out as needed, greatly facilitating the operation of the operator.

[0030] According to an exemplary solution, the additional optical device further comprises a sensor that sends a signal when the optical body slides to the working position.

[0031] According to an exemplary embodiment, the additional optical device further comprises an electrical connection interface for electrically connecting the optical main body and the microscope so as to conduct power and / or exchange information between the microscope and the optical main body.

[0047] The technical solution of the present invention is further specifically described below by examples and in conjunction with the accompanying drawings. The following description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the overall concept of the present invention and should not be construed as limiting the present invention.

[0048] In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments. However, it will be apparent that one or more embodiments may be practiced without these specific details.

[0049] Figure 1a FIG. 2 shows the optical path of the microscope when no additional optical device 2 is provided. Figure 1b The optical path when the additional optical device 2 is provided is shown, Figure 1c The optical path is shown after the additional optical device 2 is removed. Figure 1a-1c In the figure, the illumination path 102 and the imaging path 101 of the microscope are shown in a schematic manner, wherein the imaging optical device 131 (or imaging lens) of the microscope is located in the imaging path 101, and the illumination optical device 132 (or illumination lens) of the microscope is located in the illumination path 102.

[0050] In order to conveniently adjust the resolution of the microscope, such as Figure 1bThe figure shows an additional optical device 2 suitable for being attached to a microscope. The additional optical device 2 comprises an imaging optical device 21 suitable for being placed in an imaging path 101 of the microscope and an illumination optical device 22 suitable for being placed in an illumination path 102 of the microscope, wherein the imaging path 101 and the illumination path 102 are separated. The imaging optical device 21 does not act on the illumination path 102 and the illumination optical device 22 does not act on the imaging path 101. Figure 1a-1c This separate illumination mode is shown in the example of FIG. 1 , that is, the illumination optical path and the imaging optical path are separated, which is schematically shown in the figure by separators 13 and 20. This separate illumination mode can avoid mutual interference and reflection between the imaging path and the illumination path. The illumination optical device 22 is configured to match the imaging optical device 21, so that Figure 1b The illumination path is shown to act to project light into the field of view of the microscope.

[0051] The illumination optical device and the imaging optical device "match" in this article means that the illumination optical device 22 is matched with the imaging optical device 21, so that the changed illumination spot range (that is, the range of the illumination light beam covering the object plane) can at least cover the entire field of view of the changed imaging optical path 101 on the object plane, that is, the illumination light can at least illuminate the entire field of view of the microscope after the resolution is changed.

[0052] The imaging path 101 and the illumination path 102 are separated, the imaging optical device 21 of the additional optical device 2 changes the imaging focal length, and its illumination optical device 22 matches the imaging optical device 21, so that the illumination is adapted to the changed observation area, that is, the adjusted field of view of the microscope, to ensure sufficient illumination of the changed observation area. Moreover, by providing an additional optical device 2 suitable for attachment to the microscope 1 to change the resolution of the microscope, the imaging optical device 21 and the illumination optical device 22 of the additional optical device 2 are placed in the imaging path and the illumination path, respectively, to achieve a change in resolution, thereby avoiding the time-consuming and labor-intensive defects of replacing the imaging optical components and / or illumination optical components of the microscope in the prior art.

[0053] It should be pointed out that although Figure 1a-1c In the figure, the imaging optical device 131 of the microscope, the illumination optical device 132 of the microscope, the imaging optical device 21 of the additional optical device 2, and the illumination optical device 22 of the additional optical device 2 are all shown as lenses, but in fact, their implementation methods can be various, and can be any suitable type of single optical element or a combination of multiple optical elements.

[0054] like Figure 2 and Figure 3As shown, illumination optics 22 are configured to fold the illumination path of the microscope to project light into the field of view of the microscope.

[0055] Figure 2 An embodiment of an additional optical device 2 attached to a microscope 1 according to the present invention is schematically shown, the microscope 1 includes a housing 11, and the additional optical device 2 is adapted to be detachably attached to the housing 11, in such a way that the additional optical device 2 can be conveniently removed or attached as needed. The specific structure will be described in detail below.

[0056] like Figure 2 Schematically shown, the illumination optics 22 of the additional optical device 2 may include a pair of mirrors that reflect light from the illumination path 102 of the microscope, deflect the illumination path, and project the light onto the field of view of the changed imaging optical path on the object plane.

[0057] Figure 3 Schematically shows an additional optical device according to another embodiment attached to a microscope 1. Figure 2 The difference is, Figure 3 The illumination optical device 22 of the additional optical device 2 in the embodiment of the present invention adopts a pair of prisms, which change the direction of the illumination path and project the light onto the changed observation field. Using prisms instead of reflectors can reduce the adjustment of the illumination optical device and save space. In addition, the accuracy of guiding the illumination light path can be improved, and fewer optical elements are required.

[0058] In the above Figure 2 and Figure 3 In the illustrated solution, the illumination path is changed by a pair of prisms or a pair of reflectors, and the position of the illumination spot is changed so that it can match the imaging optical component and illuminate at least the entire field of view of the microscope after the resolution is changed.

[0059] It should be noted that, although in the above two examples and their corresponding drawings, the illumination optical device 22 of the additional optical device 2 is described by taking a pair of reflectors or a pair of prisms as an example, the illumination optical device 22 of the additional optical device 2 may also be other components, such as one or more reflectors, prisms or lenses or a combination thereof, as long as the focal length of the illumination optical device can be matched with the imaging optical device 21 of the additional optical device 2, and the light can be projected into the changed field of view of the microscope to at least illuminate the entire field of view.

[0060] The present invention also provides a microscope assembly, which may include a microscope and one or more additional optical devices, each of which may include imaging optical devices of different compositions or functions and matching illumination optical devices, so that a variety of resolutions can be obtained when combined with the microscope. Exemplarily, a plurality of additional optical devices may be combined into a kit to provide a range of resolution options, and an operator may select different additional optical devices as needed.

[0061] The microscope of the present invention may include a zoom lens to achieve more magnifications. And the additional optical device of the present invention is superimposed on such a microscope, and a wider range of magnification variations can be obtained as a whole. The additional optical device of the present invention can be applied to at least a part of the magnification variation range of the microscope, preferably to the entire magnification variation range of the microscope, that is, to all zoom magnifications of the microscope. In other words, for the optical parameter setting of the microscope, the additional optical device can exert a further effect to change the focal length and the corresponding illumination.

[0062] Furthermore, the imaging optical device of the additional optical device can be a fixed-focus lens or a zoom lens. The illumination optical device can be a fixed-focus lens or a zoom lens. When the additional optical device uses a zoom lens, the microscope can obtain a larger magnification range and thus a wider range of applications.

[0063] Figure 4 A schematic diagram of a microscope assembly is shown, wherein a microscope and an optical main body are schematically shown in the form of a rectangular frame, and an additional optical device is mounted on the microscope and shown in a partial cross-sectional view. Figure 5 A front view of an additional optical device is schematically shown, wherein the optical main body is schematically shown in the form of a rectangular frame. Figure 6 The additional optics are schematically shown in a top view, wherein the cover above the sensor is removed in order to view the sensor. Figure 7 A schematic perspective view schematically showing the connection portion of an additional optical device, wherein the locking fitting is clearly shown. Figure 8 Schematically shows Figure 5 The additional optical device is shown in a cross-sectional view along line L1 - L1 , in which the locking member 233 is clearly shown. Fig. 9 A perspective view of a receiving seat is shown schematically.

[0064] As a specific example of removably attaching the additional optical device 2 to the housing 11, Figure 4-9As shown, the additional optical device 2 includes a fixing member, for example, in the form of a receiving seat 23, which is suitable for fixing to the housing 11 of the microscope 1. The additional optical device 2 also includes a main body 24, wherein the main body 24 includes an optical main body portion 243 and a connecting portion 241. The illumination optical device 22 and the imaging optical device 21 are arranged in the optical main body portion 243, and the connecting portion 241 is suitable for being removably connected to the fixing member. The illumination optical device 22 and the imaging optical device 21 are arranged in the optical main body portion 243. Figure 4-6 Not shown in Figure 4-6 In the figure, the microscope 1 and the optical main body 243 are schematically shown in the form of a rectangular frame to simplify the drawing.

[0065] In this example, by removably connecting the connecting portion 241 to a fixing member fixed to the microscope, only the fixing member is fixed to the housing 11 in a normal state, and the main body 24 can be removed from the fixing member, and the connecting portion 241 of the main body 24 can be connected to the fixing member again when necessary.

[0066] like Figure 4-9 As shown, as an example, the fixing member can be in the form of a receiving seat 23. The receiving seat 23 includes a first wall 231 suitable for connecting to the shell 11 and a second wall 232 opposite to the first wall 231. The connecting portion 241 of the main body 24 is suitable for being inserted between the first wall 231 and the second wall 232. This structure is conducive to achieving accurate positioning of the connecting portion 241 of the main body 24 relative to the receiving seat 23. As an example, the connecting portion 241 includes three parallel rod-shaped members 2411, which slide relative to the receiving seat 23 so as to enter the receiving seat 23, and are fixed by the locking component 233 and the positioning member 25 which will be described in detail below. Figure 8 As shown, the three rod-shaped members 2411 can be arranged so that the two rod-shaped members 2411 on both sides respectively abut against the inner wall of the receiving seat 23 at their upper and lower surfaces and outer side surfaces to prevent shaking. Those skilled in the art can understand that the structure of the receiving seat 23 and the connecting portion 241 inserted therein is only an exemplary structure, and other connection structures can also be used as long as the main body 24 can be removably connected to the fixing member.

[0067] As an example, the optical body portion 243 of the body 24 can be fixedly connected to the connecting portion 241, for example, by a threaded fastener (not shown). When the connecting portion 241 is fixed in place in the receiving seat 23, the illumination optical device and the imaging optical device in the optical body portion 243 are respectively placed in the illumination optical path and the imaging optical path of the microscope.

[0068] For realizing the positioning of the connecting portion 241 in the receiving seat 23, the present invention provides such a solution, for example: Figure 7 , 8As shown, the accommodating seat 23 is provided with a locking hole 234 extending from its outer surface to its internal accommodating space and a locking component 233 arranged through the locking hole 234, and a locking mating portion 242 is provided on the insertion end of the connecting portion 241, and the locking component 233 is suitable for cooperating with the locking mating portion 242 to lock or release the connecting portion 241. As a specific example, the locking component 233 may include a spring 2331 and a locking member 2334 that interacts with the spring 2331 and is suitable for being pressed so as to be able to slide relative to the accommodating seat 23. The locking member may be in the form of a button. The spring 2331 abuts against a spring seat 2332 formed on the accommodating seat 23. A stopper 2335 is formed on the locking member 2334. The stopper 2335 is suitable for cooperating with the locking mating portion 242 as shown. Figure 7 The spring 2331 biases the locking member 2334 toward the outside of the receiving seat 23. Under the bias of the spring 2331, the locking member 2334 is positioned against the bushing 2336 with its step portion 2333. In this position, the stopper 2335 and the stopper surface 2421 cooperate to keep the connecting portion 241 in place relative to the receiving seat 23. Preferably, as Figure 7 As shown, a guide surface 2422 is also formed on the locking fitting portion 242. In the process of pushing the connecting portion 241 of the main body 24 into the receiving seat 23, the guide surface 2422 contacts the stopper 2335 on the locking member 2334. The stopper 2335 is as shown in FIG. Figure 7 The visible inclined guide surface 2422 enters into the groove 2423 and cooperates with the two stop surfaces 2421 (the two side surfaces of the groove 2423) to block the continued insertion of the connecting part 241 or the retraction of the connecting part 241, thereby locking the connecting part 241 and the entire main body 24.

[0069] When it is necessary to release the connecting part 241, the locking piece 2334 can be pressed, and the locking piece 2334 overcomes the biasing force of the spring 2331 and slides toward the inside of the accommodating seat until the stop piece 2335 disengages from the stop surface 2421 and moves out of the groove 2423, thereby no longer blocking the retraction of the connecting part 241. Therefore, the connecting part 241 can be pulled out and the main body 24 can be moved away from the accommodating seat 23.

[0070] Preferably, a sensor 235 may be provided on the receiving seat 23 to send a signal when the connecting portion 241 is inserted into the receiving seat to indicate that the connecting portion 241 is inserted into place, and further may be used to indicate that the optical main body 243 is in place in the optical path of the microscope and the ready state of the additional optical device. Exemplarily, the sensor 235 may be a trigger switch to be triggered when the connecting portion 241 is inserted into place. Figure 6As shown, the sensor 235 is exemplarily disposed inside the receiving seat 23, and the receiving seat 23 is provided with an electrical connection interface 236, one end of which is connected to the receiving seat 236 by means of Figure 6 The wire 2361 shown is electrically connected to the sensor 235, and the other end is suitable for being electrically connected to the microscope to transmit the sensor signal to the microscope itself. Figure 6 In the top view shown, in order to show the sensor 235 in the receiving seat 23, the cover 2351 (in Fig. 9 Moreover, those skilled in the art can also understand that the sensor 235 is not limited to being disposed inside the housing 23, and can also be disposed at any position of the housing 23, or on the connecting portion 241, or even on the housing 11 of the microscope 1.

[0071] For the above-mentioned electrical connection interface 236, illustratively, it can be connected to the microscope 1 via a cable (not shown in the figure). Exemplarily, the electrical connection interface 236 can also be configured to automatically connect to a corresponding electrical connection interface on the microscope 1 when the receiving seat 23 is connected to the housing 11 of the microscope 1, and the electrical connection interface is, for example, in the form of an electrical contact or a spring.

[0072] Through the above electrical connection interface, information can be transmitted and power can be supplied between the microscope 1 and the additional optical device. Exemplarily, the electrical connection interface can also be a wireless communication interface, and the additional optical device can be powered by, for example, a battery. The additional optical device also includes a control device (not shown in the figure), and the control device exchanges information with the microscope via the electrical connection interface. The control device includes, for example, a memory and a processor. Through the electrical connection interface, for example, information about the additional optical device can be provided to the microscope, such as the type, parameters, settings, etc. of the additional optical device. Alternatively and additionally, information about the microscope can also be provided to the additional optical device, such as the type of the microscope, setting parameters about the imaging path or the illumination path, settings about the illumination source, etc. This structure facilitates the automatic control of the microscope assembly, especially for a microscope using a zoom lens and / or an additional optical device using a zoom lens, exchanging current setting information about the microscope or the additional optical device through the electrical connection interface facilitates the corresponding control of the zoom lens.

[0073] For example, Figure 4 , 5As shown in FIG. 7 , in order to realize the precise positioning of the connecting portion and thus the main body 24 relative to the microscope 1, so as to realize the precise positioning of the imaging optical device and the illumination optical device in the optical main body 243 in the imaging path and the illumination path of the microscope, the additional optical device 2 further includes a positioning member 25, which passes through the second wall 232 and the connecting portion 241 and is fixed on the first wall 231. Specifically, as shown in FIG. Figure 4 , 5 As shown, the positioning member 25 is in the form of a knob, and an external thread is provided at its top end. The positioning member 25 passes through a hole formed on a rod-shaped member 2411 in the middle of the connecting portion 241, and the external thread at the top end is screwed into the internal thread hole on the first wall 231 of the receiving seat 23, thereby realizing accurate positioning of the connecting portion 241 in the insertion direction. The positioning member 25 is provided so that, in addition to the connection between the locking member 233 and the locking mating portion 242, the connecting portion 241 is fixed in a direction perpendicular to the insertion direction of the connecting portion 241, thereby ensuring the positioning accuracy of the connecting portion 241 in the receiving seat 23.

[0074] For example, Figure 4 It can be seen that a protrusion 12 is formed on the housing 11 of the microscope 1, and the protrusion 12 is, for example, a protruding plate-like structure. A recessed portion 237 is formed on the receiving seat 23 of the additional optical device 2. The outer peripheral edge of the protrusion 12 abuts against the outer peripheral edge of the recessed portion 237 to accurately position the receiving seat 23 relative to the microscope 1, thereby accurately positioning the additional optical device 2. The receiving seat 23 is fixed to the housing 11 by fasteners such as screws passing through the holes formed at the recessed portion, or the receiving seat 23 is fixed to the housing 11 by other means.

[0075] As an alternative, the optical main body of the additional optical device can slide relative to the microscope (this embodiment is not shown in the drawings). The additional optical device includes a fixing member suitable for fixing to the housing of the microscope, and the optical main body is slidably connected to the fixing member. The fixing member can be a single fixing member or can be in the form of a plurality of fixing members. Figure 4-9 In the embodiment of the present invention, the combined fixing member is composed of the accommodating seat 23 and the connecting portion 241.

[0076] The sliding connection between the optical main body and the fixing member can be realized by providing a slide groove in the optical main body for the fixing member to slide therein. The slide groove can be formed inside the optical main body or on its outer side wall. In this way, after the fixing member is fixedly connected to the housing of the microscope, the optical main body can slide relative to the fixing member and then relative to the microscope, so that when the illumination optical device and the imaging optical device of the additional optical device are needed to help adjust the resolution of the microscope, the optical main body can be slid to move the illumination optical device and the imaging optical device into the illumination optical path and the imaging optical path respectively, that is, into the working position. When the additional optical device is not needed, the optical main body can be slid to move the illumination optical device and the imaging optical device out of the illumination optical path and the imaging optical path respectively. Under normal conditions, the optical main body is suspended in a standby position outside the illumination optical path and the imaging optical path by the fixing member. This structure enables the optical main body of the additional optical device to be quickly moved in and out as needed, greatly facilitating the operation of the operator.

[0077] For the embodiment that the optical main body of the additional optical device can slide relative to the microscope, the sensor of the additional optical device can be arranged so as to be triggered when the optical main body slides to the above-mentioned working position. In this configuration, the sensor can be arranged on the optical main body, on the fixing part, or on the housing of the microscope.

[0078] Additionally or alternatively, the sensor may also include an electrical connection interface, and a corresponding electrical connection interface is also formed on the optical body. When the optical body is positioned in place, the electrical connection interface in the sensor is connected to the electrical connection interface of the optical body. In this way, the microscope can be electrically connected to the optical body, so that when the optical body is positioned in place, that is, the imaging optical device and the illumination optical device are placed in the imaging path and the illumination path respectively, power can be supplied and / or information can be exchanged between the microscope and the optical body.

[0079] Although some embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the claims and their equivalents.
