Description

Technical Field

[0001] This utility model relates to the technical field of laser applications, and in particular to a large-spot laser application device. Background Technology

[0002] Currently, most multicolor fluorescence imaging systems, in vivo animal and plant imaging systems, and biochip detection imaging systems on the market use LEDs as excitation sources for various devices that employ light source excitation, while some use halogen or xenon lamps. However, LED light sources have low excitation efficiency, limited penetration, and suffer from problems such as impure light sources and scattered light spots. Filters need to be installed at the front end of the light source during use, and they are not conducive to sample observation and excitation. Halogen or xenon lamps are relatively large and bulky, making them difficult to install within the imaging system, and different filters need to be switched during use to achieve the desired excitation source.

[0003] Meanwhile, in existing technologies, the height adjustment of the light source projection plate in imaging systems is inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a large-spot laser application device to solve the problem that the light source of the existing imaging system cannot meet the usage requirements.

[0005] To address the aforementioned technical problems, this utility model provides a large-spot laser application device, comprising a device box, an angle adjustment plate, a laser light source, and a projection plate disposed within the device box; two angle adjustment plates are respectively disposed on both sides above the projection plate, and the laser light source is mounted on each of the two angle adjustment plates; the irradiation direction of the laser light source is aligned with the projection plate, and the laser light source and the angle adjustment plate are connected to form an adjustable irradiation angle structure.

[0006] In one embodiment, the optional types of the laser light source include red laser light source, blue laser light source, green laser light source, yellow laser light source, far-infrared laser light source, near-infrared laser light source, and infrared zone II laser light source.

[0007] In one embodiment, one of the angle adjustment plates is provided with the red laser light source, the blue laser light source, and the green laser light source; the other angle adjustment plate is provided with the far-infrared laser light source, the near-infrared laser light source, and the yellow laser light source.

[0008] In one embodiment, the laser emission end of the laser light source is provided with a grating mirror.

[0009] In one embodiment, the optional types of the grating mirror include rectangular spot grating mirrors, elliptical spot grating mirrors, and solid circular spot grating mirrors.

[0012] The beneficial effects of this utility model are as follows:

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] This invention provides a large-spot laser application device, the implementation of which is as follows: Figure 1 and Figure 2 As shown, the device includes a housing 100, and an angle adjustment plate 200, a laser light source 300, and a projection plate 400 disposed within the housing 100. The two angle adjustment plates 200 are respectively disposed on both sides above the projection plate 400, and a laser light source 300 is mounted on each of the two angle adjustment plates 200. The irradiation direction of the laser light source 300 is aligned with the projection plate 400, and the laser light source 300 is connected to the angle adjustment plate 200 to form an adjustable irradiation angle structure.

[0026] This embodiment uses a large-spot laser light source 300 to replace traditional LED, halogen, and xenon lamp light sources in combination with CCD camera imaging. Laser has the advantages of high excitation efficiency and strong penetration, thus greatly improving the excitation sensitivity of samples. It solves the problem of poor excitation effect or failure to excite weak signals by traditional LEDs. Moreover, the background is clean and there is little stray light, making it the best light source for CCD cameras in multicolor fluorescence chemiluminescence gel imaging systems and live animal and plant imaging systems.

[0027] In this embodiment, the optional types of laser light source 300 include red laser light source, blue laser light source, green laser light source, yellow laser light source, far-infrared laser light source, near-infrared laser light source, and infrared zone II laser light source.

[0028] Specifically, such as Figure 2 As shown, one of the angle adjustment plates 200 (left side of the diagram) is equipped with a red laser light source, a blue laser light source, and a green laser light source; the other angle adjustment plate 200 (right side of the diagram) is equipped with a far-infrared laser light source, a near-infrared laser light source, and a yellow laser light source, thus meeting the needs of using a variety of different light sources.

[0029] In addition, in this embodiment, the laser emission end of the laser light source 300 is provided with a grating mirror to make the light source purer and the effective light spot more uniform.

[0030] Specifically, the types of gratings available include rectangular spot gratings, elliptical spot gratings, and solid circular spot gratings, and the appropriate type can be selected based on the actual application requirements.

[0031] like Figure 2As shown, in this embodiment, the angle adjustment plate 200 is arranged at an angle relative to the projection plate 400, and the laser light source 300 is arranged on the angle adjustment plate 200 with the irradiation direction tilted downward.

[0032] With this setup, the laser light source 300 can be arranged with the irradiation direction angled downwards, so that the laser light source 300 can accurately irradiate the projection plate 400.

[0033] like Figure 3 and Figure 4 As shown, in this embodiment, the angle adjustment plate 200 is provided with an arc-shaped groove 210, and the laser light source 300 is slidably installed in the arc-shaped groove 210.

[0034] With this configuration, the laser light source 300 can slide along the arrangement trajectory of the arc groove 210 to adjust its position. The laser light source 300 can also rotate on the arc groove 210, thus realizing various angle adjustment requirements of the laser light source 300.

[0035] To achieve a sliding connection between the laser light source 300 and the arc groove 210, a structure such as a pin can be provided on the laser light source 300. By using the pin to pass through the arc groove 210, a sliding connection between the laser light source 300 and the arc groove 210 can be achieved. Moreover, by simply setting a corresponding nut at the end of the pin for locking, the positioning between the laser light source 300 and the arc groove 210 can be achieved.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
