Description

Technical Field

[0001] The invention relates to the technical field of optical illumination, and in particular to a light-guiding microscope. Background Art

[0002] Nowadays, microscopes, as a precision optical instrument, have been widely used in different fields, especially in medicine, biology, experimental teaching and other fields. Its performance depends largely on the light source device under the microscope. Traditional microscopes basically use an independent downlight LED as the light source, which is large in size, high in cost, and generally cannot achieve the expected illumination effect. Therefore, in order to make the LED illumination effect of the microscope play the best state and achieve a bright field of view, no glare, and uniform illumination, it is necessary to carry out optical design based on the characteristics of the microscope's illumination system. Summary of the invention

[0003] In order to solve the above problems, the object of the present invention is to provide a light-guiding microscope with small size, low cost and good light-guiding irradiation performance.

[0004] The technical solution adopted by the present invention to solve the technical problem is:

[0005] A light-guiding microscope, comprising:

[0006] A stage, which is used to place specimens or specimen slides;

[0007] A light source, the light source is arranged above the stage;

[0008] An objective lens system, wherein the objective lens system is arranged above the stage and is located on the same side as the light source;

[0009] The light guide system is formed in the stage. The light emitted by the light source passes through the stage and is reflected by the light guide system therein and transmitted to the specimen or the bottom surface of the specimen slice on the stage.

[0010] As an improvement of the above technical solution, the stage is made of optical-grade light-transmitting plastic material and is integrally formed.

[0011] As a further improvement of the above technical solution, the light guiding system includes a first reflecting mirror surface correspondingly formed in the stage, and the first reflecting mirror surface is used to reflect the light emitted by the light source and transmit it to the bottom surface of the specimen or specimen slide on the stage.

[0012] Further preferably, the first reflective mirror surface is correspondingly located below the center of a line connecting the light source and the objective lens system.

[0013] In the present invention, the light guiding system further comprises a second reflecting mirror surface correspondingly arranged below the light source, and a third reflecting mirror surface correspondingly arranged below the objective lens system, wherein the second reflecting mirror surface is used to reflect the light emitted by the light source onto the third reflecting mirror surface, and the third reflecting mirror surface then transmits the light to the bottom surface of the specimen or specimen slide on the stage.

[0014] Preferably, the second reflective mirror surface and the third reflective mirror surface are both integrally formed in the stage.

[0015] Preferably, the second reflective mirror surface and the third reflective mirror surface are both prism-shaped.

[0016] Preferably, the light source is a low voltage light source.

[0017] Beneficial effects of the present invention: The present invention includes an objective lens system, a stage, a light source, an objective lens system, and a light guide system. The stage is used to place specimens or specimen slices. The light source is arranged above the stage. The objective lens system is arranged above the stage and is located on the same side as the light source. The light guide system is formed in the stage. The light emitted by the light source passes through the stage and is reflected and transmitted to the bottom surface of the specimen or specimen slice on the stage by the light guide system therein. In this way, the present technical solution emits light through the light source, then passes through the stage, and then is reflected and transmitted to the bottom surface of the specimen or specimen slice on the stage by the light guide system in the stage. Compared with the traditional technology that uses an independent down-light LED as a light source, the present technical solution realizes light conduction through the combination of the stage and the light guide system. It not only has a simple structure, a small size, and low cost, but is also easy to process, has soft light, and has good light guide irradiation performance. At the same time, it also eliminates the lighting structure below the stage, simplifies the entire system, provides a good user experience, and has broad application prospects, thereby greatly enhancing the market competitiveness of manufacturers.

[0022] Reference Figure 1 , Figure 2 A light-guiding microscope comprises a stage 10, a light source 20, an objective lens system 30, and a light-guiding system 40. The stage 10 is used to place a specimen or a specimen piece. The light source 20 is arranged above the stage 10. The objective lens system 30 is arranged above the stage 10 and is located on the same side as the light source 20. The light-guiding system 40 is formed in the stage 10. The light emitted by the light source 20 passes through the stage 10 and is reflected and transmitted to the bottom surface of the specimen or the specimen piece on the stage 10 by the light-guiding system 40 therein. In this way, the technical solution emits light through the light source 20. Secondly, The light is transmitted through the stage 10 and then reflected by the light guide system 40 inside the stage 10 and transmitted to the specimen or the bottom surface of the specimen on the stage 10. Compared with the traditional technology that uses an independent downlight LED as a light source, the present technical solution realizes light conduction through the combination of the stage 10 and the light guide system 40. It not only has a simple structure, a small size, and a low cost, but is also easy to process, with soft light and good light guiding performance. At the same time, it also eliminates the lighting structure under the stage, simplifies the entire system, provides a good user experience, and has broad application prospects, thereby greatly enhancing the market competitiveness of manufacturers.

[0023] Preferably, the stage 10 is made of an optical-grade light-transmitting plastic material by integral molding. The optical-grade light-transmitting plastic material is heat-resistant, temperature-resistant, weather-resistant, impact-resistant, strength-resistant and environmentally friendly. However, the present invention does not limit the stage 10 to be made of an optical-grade light-transmitting plastic material. As long as the same technical effects are achieved by basically similar technical means, they are within the protection scope of the present invention.

[0024] The first preferred embodiment of the present invention: the light guiding system 40 includes a first reflecting mirror surface correspondingly formed in the stage 10, the first reflecting mirror surface is used to reflect the light emitted by the light source 20 and transmit it to the bottom surface of the specimen or specimen piece on the stage 10, the first reflecting mirror surface is correspondingly located below the center of the line connecting the light source 20 and the objective lens system 30, here, the first reflecting mirror surface can be formed in the stage 10 by casting molding, and the casting molding method not only has less production investment, but also can produce products with excellent performance. In this way, the technical scheme first emits light through the light source 20, then passes through the stage 10, and then is reflected and transmitted to the bottom surface of the specimen or specimen piece on the stage 10 by the first reflecting mirror surface correspondingly arranged below the center of the line connecting the light source 20 and the objective lens system 30 and located in the stage 10.

[0025] In a second preferred embodiment of the present invention, the light guide system 40 further includes a second reflective mirror surface 41 correspondingly arranged below the light source 20, and a third reflective mirror surface 42 correspondingly arranged below the objective lens system 30. The second reflective mirror surface 41 is used to reflect the light emitted by the light source 20 onto the third reflective mirror surface 42, and the third reflective mirror surface 42 transmits the light to the bottom surface of the specimen or specimen slide on the stage 10. Preferably, the second reflective mirror surface 41 and the third reflective mirror surface 42 can be molded in the stage 10 by casting. Further preferably, the second reflective mirror surface 41 and the third reflective mirror surface 42 are both prism-shaped. Of course, the present invention is not limited to a prism-shaped shape, and may be other shapes. As long as the same technical effects are achieved by similar technical means, they are within the protection scope of the present invention. In this way, the present technical solution first emits light through the light source 20, and then passes through the stage 10, and the second reflecting mirror surface 41 under the light source 20 reflects the light to the third reflecting mirror surface 42 under the objective lens system 30, and then transmits the light to the bottom surface of the specimen or specimen on the stage 10 through the third reflecting mirror surface 42. In this way, the present technical solution makes the light softer through the cooperation of the stage 10 with the second reflecting mirror surface 41 and the third reflecting mirror surface 42, and the light irradiation performance is better.

[0026] Preferably, the light source 20 is a low-voltage light source.

[0027] The above specifically describes the preferred implementation of the present invention. Of course, the present invention can also take a form different from the above-mentioned implementation mode. Equivalent changes or corresponding modifications made by technicians familiar with the field without violating the spirit of the present invention should fall within the scope of protection of the present invention.
