Description

Technical Field

[0001] This utility model relates to the field of microscopic imaging technology, and specifically to a microscopic projection system with switchable projection wavelength. Background Technology

[0002] Currently, microscopes are widely used in the life sciences and related industrial fields. However, traditional microscope systems have drawbacks such as small field of view and limited functionality, mainly in the following two aspects:

[0003] (1) Single wavelength: Current microscope projection uses a single wavelength, which is not universal for fields that require multiple wavelengths.

[0004] 2) Changing the projection wavelength requires optical path adjustment, resulting in low experimental and testing efficiency.

[0005] 3) Compared with the color-combining prism projection method currently used in projectors, its wavelength selectivity is limited. Due to the coating of the prism beam combining surface, it can only be used with light sources that are significantly different from three different light sources. Usually, the difference in center wavelength needs to be greater than 100nm. However, in biological applications, where precise specific wavelengths are required for projection or stimulation, this method cannot be achieved. Summary of the Invention

[0006] Therefore, it is necessary to provide a microscopic projection system with switchable projection wavelengths to address the existing problems.

[0007] This application provides a microscopic projection system with switchable projection wavelength, characterized in that it includes a light source module, a projection module, and a microscope system;

[0008] The light source module includes a first light source structure and a second light source structure. When the first light source structure or the second light source structure is in the emission position, it can emit a light beam. The light beam enters the projection module, and the light beam processed by the projection module enters the microscope system.

[0009] The light source module further includes a displacement structure, which is used to switch the first light source structure or the second light source structure to the emission position.

[0010] Preferably, the displacement structure includes a guide rail and a driver, the first light source structure and the second light source structure are disposed on the guide rail, and the driver can drive the first light source structure and the second light source structure to reciprocate on the guide rail so as to set the first light source structure and the second light source structure at the emission position.

[0011] Preferably, the wavelength of the first light beam emitted by the first light source structure is different from the wavelength of the second light beam emitted by the second light source structure, and the displacement structure can drive multiple light source structures with different wavelengths to the emission position respectively.

[0012] Preferably, the light source module further includes at least a third light source structure that emits a third beam, the third light source structure being disposed on the guide rail, and the driver being able to drive the third light source structure to reciprocate on the guide rail.

[0013] Preferably, the dual-path microscopic projection optical system further includes a third motor, a fourth motor, and a fifth motor for controlling the objective lens assembly;

[0014] The third motor is used to control the change of the X-axis position of the objective lens assembly; the fourth motor is used to control the change of the Y-axis position of the objective lens assembly; and the fifth motor is used to control the change of the Z-axis position of the objective lens assembly.

[0015] Preferably, the bright-field imaging optical path and the fluorescence imaging optical path are coaxial.

[0016] Compared with the prior art, the technical solution disclosed in this utility model has the following beneficial effects:

[0017] (1) The first light source structure and the second light source structure of the present invention share a projection module and a microscope module. By switching the first light source structure and the second light source structure, the problem of single wavelength can be solved and the operator's needs for light sources of different wavelengths can be met.

[0018] (2) By using a displacement structure to switch between the first light source structure and the second light source structure, when the first light source structure or the second light source structure reaches the emission position, the structured light projection can be normally operated by emitting a beam.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. Example

[0029] like Figure 1 As shown, this application provides a microscopic projection system with switchable projection wavelength, characterized in that it includes a light source module 201, a projection module 102, and a microscope system.

[0030] The light source module 201 includes a first light source structure 101 and a second light source structure 104. When the first light source structure 101 or the second light source structure 104 is in the emission position, it can emit a light beam. The light beam enters the projection module 102, and the light beam processed by the projection module 102 enters the microscope system.

[0031] The light source module 201 also includes a displacement structure, which is used to switch the first light source structure 101 or the second light source structure 104 to the emission position.

[0032] The beneficial effects of this invention are that by sharing a projection module 102 and a microscope module 103 between the first light source structure 101 and the second light source structure 104, the problem of single wavelength can be solved by switching between the first light source structure 101 and the second light source structure 104, thus meeting the operator's needs for light sources of different wavelengths; by using a displacement structure to switch between the first light source structure 101 and the second light source structure 104, when the first light source structure 101 or the second light source structure 104 reaches the emission position, the structured light projection can be normally operated by emitting a beam.

[0033] Preferably, such as Figure 2 As shown, the displacement structure includes a guide rail 204 and a driver. The first light source structure 101 and the second light source structure 104 are mounted on the guide rail 204. The driver can drive the first light source structure 101 and the second light source structure 104 to reciprocate on the guide rail 204, thereby positioning them in the emission position. The displacement of the first light source structure 101 and the second light source structure 104 is achieved through a single guide rail 204, allowing for a predetermined stroke and precise movement. Furthermore, the operator can switch between the first light source structure 101 and the second light source structure 104 simply by issuing a switching command, based on the preset emission position. Once the first light source structure 101 and the second light source structure 104 reach their predetermined positions, they can normally emit light beams. Multiple different light source modules 201 are mounted on the same elongated slider 202. The guide rail 204 is a linear guide rail 204, which makes each slider 202 move in a specified direction. The slider 202 can be automatically switched by setting a motor 203.

[0034] Preferably, the wavelength of the first beam emitted from the first light source structure 101 is different from the wavelength of the second beam emitted from the second light source structure 104, and the displacement structure can drive multiple light source structures with different wavelengths to the emission position respectively. By setting the wavelength of the first beam emitted from the first light source structure 101 to be different from the wavelength of the second beam emitted from the second light source structure 104, specifically, the operator can set the emission beam wavelengths of the first light source structure 101 and the second light source structure 104 according to actual usage requirements, and then change them according to usage requirements during actual use to meet the needs of its specific usage environment. According to current biological applications, the light source wavelength of 301 may include 390nm, 450nm, 510nm, 617nm and other available wavelengths.

[0035] Preferably, such as Figure 1 or Figure 2 As shown, the light source module 201 also includes at least a third light source structure 105 that emits a third beam. The third light source structure 105 is mounted on the guide rail 204, and the driver can drive the third light source structure 105 to reciprocate on the guide rail 204. By setting the third light source structure 105, or adding more light source structures of other wavelengths, the operator can set up multiple wavelength light source modules 201 under complex usage requirements and achieve wavelength adjustment.
