[0043] Please refer to the attached document. Figures 1-4 In this embodiment, the housing 10 serves as a support component for the reflective imaging module 100, and the housing 10 is used to support the LED light source 20, the reflector 30, and the objective lens 40.

[0044] The LED light source 20 is integrated on the outside of the housing 10, with the output end of the LED light source 20 facing the inside of the housing 10. The LED light source 20 is used to output light so that the light output by the LED light source 20 can be transmitted into the housing 10.

[0045] The reflector 30 is located inside the housing 10 and is arranged in an inclined direction; the reflector 30 is used to receive the light output by the LED light source 20; so that the light output by the LED light source 20 is refracted in different directions by the reflector 30, thereby facilitating the light output by the LED light source 20 to extend in the vertical direction of the housing 10.

[0046] The objective lens 40 is disposed on the lower side of the housing 10 and is connected to the housing 10 so that the objective lens 40 can be fixed on the lower side of the housing 10, thereby making full use of the lower space of the housing 10.

[0048] The camera 60 is located on the upper side of the housing 10, making full use of the upper space of the housing 10. The camera 60 is used to photograph the SPR chip 52 unit 50 and capture color images, so that the camera 60 can shoot the SPR chip 52 unit 50 from top to bottom, so as to realize the acquisition and real-time generation of SPR signals in microscopic imaging.

[0049] Please refer to the attached document. Figures 1-3 In this embodiment, the housing 10 is provided with a receiving groove 10a; the receiving groove 10a serves as the internal space of the housing 10, and the reflector 30 is located within the receiving groove 10a, with the reflector 30 arranged at an angle relative to the housing 10; this allows the housing 10 to accommodate the reflector 30 through the receiving groove 10a, thereby facilitating the integration of the reflector 30 into the housing 10. Both ends of the reflector 30 are positioned close to opposite corners within the housing 10, so that the opposite corners of the housing 10 abut against the reflector 30, ensuring the tilting effect of the reflector 30.

[0050] Please refer to the attached document. Figures 1-3In this embodiment, the LED light source 20 is installed on the outer wall of the housing 10 so that the LED light source 20 can be fixed to the outer wall of the housing 10. The housing 10 is provided with a light-transmitting hole. The light output by the LED light source 20 passes through the light-transmitting hole and illuminates the reflective surface of the objective lens 40 so that the light output by the LED light source 20 can be transmitted to the reflector 30 through the light-transmitting hole, thereby facilitating the reflector 30 to reflect the light to the reflective surface of the objective lens 40, so that the light output by the LED light source 20 can illuminate the objective lens 40.

[0051] Please refer to the attached document. Figures 1-2 In this embodiment of the application, there are multiple LED light sources 20, which are arranged along the vertical direction. By arranging multiple LED light sources 20, the effective coverage range of the light source is expanded. Multiple LED light sources 20 illuminate the reflective surface of the same objective lens 40 at different height positions, so that the light forms a relatively uniform light intensity distribution on the reflective surface of the objective lens 40.

[0052] Please refer to the attached document. Figures 1-3 In this embodiment, the reflector 30 is a semi-transmissive and semi-reflective mirror; a semi-transmissive and semi-reflective mirror can split and reflect light. The LED light source 20 is a white light source so that it can output white light.

[0053] Please refer to the attached document. Figures 1-3 In this embodiment, the objective lens 40 is detachably connected to the lower end of the housing 10 so that the objective lens 40 can be connected to or detached from the housing 10, which improves the ease of replacing the objective lens 40. The surface of the objective lens 40 away from the housing 10 is elliptical. The elliptical objective lens 40 can reflect all the light emitted by the mirror 30 to the SPR chip 52 so that the SPR chip 52 can receive the light converged by the objective lens 40.

[0054] Please refer to the attached document. Figure 1 and 4 In this embodiment, the SPR chip 52 is provided with a flow channel for fluid flow. This facilitates the flow of fluid to guide the analyte to the detection area of ​​the SPR chip 52.
