Description

Technical Field

[0001] The present invention relates to the technical field of optical path adjustment mechanisms, and in particular to a multi-degree-of-freedom optical path adjustment component. Background Art

[0002] During the optical path construction process for instrument experiments or equipment lighting, the light source or the position of the optical path needs to be accurately installed to achieve the conduction of the optical path. Therefore, during the optical path adjustment stage, the posture of the light source or each optical path channel must be adjusted to meet the optical path alignment requirements. At present, the posture adjustment of the light source or each optical path channel is often achieved by the supporting structure assembly at the bottom. The bottom supporting structure assembly is mainly based on the purchase of existing adjustment frames on the market, supplemented by the design of several parts to connect to form a set of multi-degree-of-freedom adjustment devices. The disadvantage is that different types of adjustment frames need to be purchased for different optical paths, and sometimes it is difficult to match the right model, so special customized products are required. In addition, the purchased products are costly, complex in structure, heavy in weight, inappropriate in size, and the customized product cycle is long. In order to ensure that the multi-degree-of-freedom adjustment device used when adjusting the posture of the light source or each optical path channel is simple in structure, easy to operate, and reasonable in size, a multi-degree-of-freedom optical path adjustment assembly is required to meet the following requirements:

[0003] a. The component should meet the principles of independent design, miniaturization and lightweight;

[0004] b. The component structure should be simple and economical;

[0005] c. The component should be of reasonable size and easy to operate;

[0007] However, using purchased components has disadvantages such as high cost, complex structure, heavy weight, inappropriate size, and long custom production cycle, and can only meet the needs of certain optical path types. Therefore, a multi-degree-of-freedom optical path adjustment component is needed to meet the above requirements and realize the optical path alignment function. Summary of the Invention
