DETAILED DESCRIPTION

[0021] The utility model will be further explained in connection with the drawings and examples.

[0022] Among the existing technologies that can be implemented, the following have been found:

[0023] As a powerful analytical tool, fluorescence spectrometers play an important role in modern scientific research and industrial detection. Whether it is to explore the mysteries of biological molecules in the microscopic world or to control the quality of materials in macroscopic industrial production, it plays an irreplaceable role. In the complex optical system of the fluorescence spectrometer, the optical fiber bears the heavy responsibility of transmitting excitation light and collecting fluorescence signals, just like the nerves of the human body, connecting various key "organs", while the optical fiber fixing support, like a stable skeleton, provides stable support and precise positioning for the optical fiber, ensuring efficient and accurate transmission of optical signals. Its performance directly affects the best performance of the spectrometer and the reliability and accuracy of the detection results.

[0024] Modular concept: Modern optical fiber fixing supports are designed with a modular concept. The main frame is usually made of lightweight and high-strength materials such as aluminum alloy. This material is light in weight, easy to install and move, and has enough strength to remain stable in different environments. The frame is divided into multiple functional modules, such as support modules, clamping modules, and adjustment modules. The modules are connected through standardized interfaces and can be assembled flexibly according to the differences in spectrometer models, the number of optical fibers, and the layout requirements. For example, in large laboratory spectrometers, multiple clamping modules may be needed to fix multiple complexly wired optical fibers, while portable spectrometers can simplify the modules to emphasize compactness and portability.

[0025] Spatial rationality: Rational planning of space layout is crucial. The internal space of the support should be reserved for the optical fiber with a sufficient bending radius to avoid excessive bending and signal loss. Generally, the bending radius of the optical fiber should be no less than 10 times its diameter. At the same time, the layout of each module should consider the convenience of operation. The adjustment knobs and interfaces should be placed in easy-to-reach places to facilitate quick adjustments by experimenters during the experiment.

[0026] Silicone: The inner lining of the clamp and the clamp used in direct contact with the optical fiber are often made of silicone material. Food-grade silicone has high elasticity, with a Shore hardness of 30-80A, which can tightly fit the surface of the optical fiber, providing stable clamping force while avoiding damage to the optical fiber. Its low friction coefficient can prevent scratches during the insertion and removal of the optical fiber, and it has good chemical stability and will not react with the optical fiber. Long-term use will not contaminate the surface of the optical fiber, ensuring that the optical signal transmission is not affected.

[0027] Polytetrafluoroethylene: Polytetrafluoroethylene is widely used in the internal circuit connection and areas prone to static electricity of the support. It has extremely low dielectric constant (about 2.0) and dielectric loss, which can effectively isolate static electricity and prevent it from interfering with optical signal transmission. Its excellent chemical stability makes it resistant to strong acid and strong base corrosion, and it can be used normally from -200°C to +260°C, ensuring the electrical insulation performance of the support in complex environments.

[0028] As a key component of the fluorescence spectrometer, the design, material and performance of the optical fiber fixing support directly affect the overall performance of the spectrometer. From the complex and delicate structure design, to the careful selection of high-quality materials, to the outstanding performance in different application scenarios, it plays an irreplaceable role in ensuring stable transmission of optical signals and improving detection accuracy. With the continuous progress of science and technology, the application field of fluorescence spectrometer continues to expand, and the performance requirements of optical fiber fixing support will become increasingly stringent.
