It is especially suitable for switching between different frequency light sources under the same incident light port. Background Technology

[0002] In optical instrument testing, researchers often need to switch between light sources of different frequencies to test samples multiple times. However, current optical path switching devices often have the following drawbacks: 1. The number of switchable optical paths is limited, which cannot meet the needs of complex experiments requiring multiple light sources; 2. The switching error is large, making it difficult to maintain the accuracy of the optical path; 3. The switching process may lead to energy loss in the optical path, affecting the accuracy of the experimental results.

[0003] In existing optical equipment, the devices for switching light sources and optical paths typically lack the ability to freely combine them, making it impossible to efficiently and flexibly switch between multiple optical paths. Therefore, designing an optical path switching device that can solve the above-mentioned shortcomings is of great significance for improving the efficiency and accuracy of optical experiments.

[0025] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0026] Please see Figure 1-3In a preferred embodiment of this utility model, a simple device for multi-optical path switching includes a dark box 1. The top of the dark box 1 is a door 2, and one side wall of the dark box 1 in the width direction is provided with a light outlet 3. At least two optical path components are installed inside the dark box 1, and all optical path components are arranged sequentially and spaced apart along the width direction of the dark box 1. Each optical path component includes a two-dimensional lifting platform 4 for placing a laser 11 and a sliding platform 7 for installing a reflector 9. The two-dimensional lifting platform 4 and the sliding platform 7 are directly opposite each other and are arranged spaced apart along the length direction of the dark box 1. The top of the two-dimensional lifting platform 4 is a table surface, and the laser 11 is placed on the table surface with its light emission direction facing the sliding platform 7. A slide rail is provided on the sliding platform 7, and the slide rail is arranged along the length direction of the dark box 1, with its two ends located on opposite sides of the light outlet 3. A slider 8 is slidably installed on the slide rail, and the slider 8 is provided with a slider locking member 10 for preventing it from sliding relative to the slide rail. The reflector 9 is movably installed on the slider 8.

[0027] This invention places the optical path components within a dark box 1. The dark box 1 isolates external light during the experiment, ensuring the purity of the optical path and preventing interference from ambient light. The top door 2 allows researchers to easily adjust the optical path components within the dark box 1 by opening the door, and then close the door after adjustment, ensuring the optical path within the dark box 1 is not affected by ambient light. Preferably, the inner wall of the dark box 1 is coated with a light-absorbing coating made of a light-absorbing material, such as carbon nanotube blackbody material, black adhesive tape, etc. No particular limitation is made, as long as it meets the light-absorbing requirements. Of course, a higher light absorption rate will result in better performance. Using a coating of high-absorbency material to absorb stray light further ensures that any possible stray light will not interfere with the experimental results, improving the accuracy of the experimental data.

[0028] In this invention, the laser 11 is mounted on a two-dimensional lifting platform 4, which can be raised and lowered by the lifting action of the platform 4, thereby adjusting the height of the laser 11. In this embodiment, the two-dimensional lifting platform 4 is a scissor-type platform, and its height can be adjusted and maintained by using a lifting rod, lead screw, or other drive components. Furthermore, a platform plate 5 is slidably mounted on the surface of the two-dimensional lifting platform 4, with the sliding direction parallel to the width direction of the darkroom 1. The laser 11 is placed on the platform plate 5, and a platform locking member 6 is installed on the platform plate 5 to prevent it from sliding relative to the platform surface. The platform locking member 6 is preferably a locking screw structure. Thus, by sliding the platform plate 5 relative to the platform surface of the two-dimensional lifting platform 4, the horizontal position of the laser 11 can also be adjusted to meet different experimental requirements. In addition, the platform locking component 6 can also be used as a driving component to drive the platform 5 to slide. In this case, the platform locking component 6 is a screw structure, which is threaded to the platform of the two-dimensional lifting platform 4, and one end is rotatably connected to the platform 5. The platform 5 is slidably connected to the platform through the track on the two-dimensional lifting platform 4. Rotating the platform locking component 6 can push the platform 5 to slide horizontally. Releasing the platform locking component 6 will keep the platform 5 in its current position.

[0029] The reflector 9 of this invention is mounted on a slide table 7 and can slide along a slide rail on the slide table 7. It can be fixed after sliding, specifically by a slider locking member 10. In this embodiment, the slider locking member 10 is preferably a locking screw structure. This allows the reflector 9 to be adjusted in position according to experimental needs. In this embodiment, to improve the flexibility of the reflector 9's position adjustment, the slider 8 and the slide rail are connected by a rolling mechanism, forming a high-precision ball bearing sliding system. The slide rail is made of high-precision ground stainless steel, ensuring low friction when the slider 8 moves on it, reducing optical path deviation while allowing for quick and convenient adjustment of the reflector 9's position. In this invention, the reflector 9, through its movable installation, can also adjust its angle to ensure that the laser beam can be accurately guided to the target position of the experimental device along a predetermined path, minimizing laser loss during reflection. Preferably, the reflector 9 is ball-jointed to the slider 8.

[0030] In this invention, during the experiment, the laser fiber emitted by the laser 11 is reflected by the reflector 9 and then emitted from the light outlet 3 on the dark box 1, and then projected onto the target area. In this embodiment, in order to ensure that the laser can be projected onto the target area with the minimum divergence angle, the structure and size of the light outlet 3 can be adjusted according to actual needs. Specifically, the simple device for multi-path switching also includes several perforated plates 12, each of which has an opening 13. The structure or size of the opening 13 on each perforated plate 12 is different. Only one perforated plate 12 can be detachably installed at the light outlet 3 at a time, and when the perforated plate 12 is installed at the light outlet 3, the opening 13 on the perforated plate 12 is directly opposite to and connected to the light outlet 3. In this way, by installing perforated plates 12 of different specifications at the light outlet 3, the outlet structure and size of the dark box 1 can be changed to meet different experimental requirements. In this embodiment, the outer wall of the darkroom 1 is provided with two slots 14, which are located on opposite sides of the light outlet 3. The perforated plate 12 is detachably installed at the light outlet 3 by engaging the two slots 14 with its side edges. In addition, considering the convenience of storing multiple perforated plates 12, the outer wall of the darkroom 1 is provided with a storage box 15 for storing the perforated plates 12, so as to store unused perforated plates 12.

[0031] The specific operation process of this utility model is as follows:

[0032] 1. Adjusting the position of the light source

[0033] In the initial stage of the experiment, the experimenters need to adjust the position of the laser 11 using the two-dimensional lifting platform 4 in order to adjust the horizontal and vertical positions of the light source.

[0034] First, loosen the stage locking piece 6, move the stage 5 to a suitable position, and then tighten the stage locking piece 6. The experimenter can then make fine-tuning adjustments to the horizontal position of the laser 11 to ensure the initial position of the light source is accurate. Next, the experimenter can adjust the height of the light source using the two-dimensional lifting platform 4 to adapt to different experimental needs.

[0035] 2. Adjustment of slide 7 and slider 8

[0036] After the laser 11 is positioned, the next step is to adjust the optical path. This adjustment is primarily performed using the slide table 7 and the slider 8. The experimenter can move the slider 8 along the slide rail to move the slide table 7, thereby positioning the three-dimensional reflector 9 to ensure it is aligned with different optical paths. When the beam reaches the reflector 9, the reflector 9 will reflect or refract the beam to the target position according to the experimental requirements.

[0037] 3. Optical path guidance of the three-dimensional reflecting mirror 9

[0038] The three-dimensional reflector 9 is the core component for adjusting the optical path assembly. It can adjust its angle in three dimensions to guide the light beam to reflect along a predetermined path. The path of the light beam is accurately guided here. Experimenters can adjust the angle of the reflector 9 on the slider 8 to guide the laser to the target area according to different requirements.

[0039] Multiple two-dimensional lifting platforms 4 and sliding platforms 7 (such as A, a; B, b; C, c...) can be placed according to the required optical path for the experiment to achieve flexible switching between light sources and ensure free combination of optical paths. It is worth noting that when adjusting a pair of two-dimensional lifting platforms 4 and sliding platforms 7 (such as A, a), the other sliding platforms 7 should be staggered from their platforms with the light outlet 3 to avoid interference with the current optical path.

[0040] Finally, it should be noted that the simple device of this utility model can be widely used in the following situations:

[0041] 1. Optical experiments require multi-source testing: In the experiment, different samples need to be tested by switching optical paths multiple times at different frequencies in order to obtain more accurate data.

[0042] 2. Complex optical path combination experiments: Some optical experiments require the simultaneous use of multiple light sources for combined testing, and the device needs to support the free combination and switching of multiple optical paths.

[0043] 3. Reduce optical path energy loss: In order to ensure the reliability of experimental results, the device should minimize optical path loss and maintain efficient energy transmission.

[0044] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
