Machine vision fibers refer to the fiber optic components and technologies used in machine vision systems. They play an important role in machine vision applications and have several common application scenarios: Fiber optic illumination: Machine vision systems often require high-brightness and uniform light sources to provide illumination conditions. Fibers can be used to transmit light from the light source, allowing it to be placed in the desired location and delivered to specific areas through fiber bundles, thus providing consistent illumination. Fiber optic sensors: Fiber optic sensors can be used to detect and measure various physical quantities in machine vision systems. For example, fiber optic displacement sensors can measure object displacement or deformation, and fiber optic temperature sensors can measure object temperature, providing accurate input data for machine vision systems. Fiber bundles: Fiber bundles can concentrate and distribute light from fiber optic light sources to adapt to specific requirements of machine vision applications. Fiber bundles can be used to focus light from the fiber optic light source to a specific area or disperse light to a larger area, meeting the demands of illumination uniformity and brightness control. Fiber optic light guides: Fiber optic light guides are ring-shaped fiber optic structures that transmit light from one point to another, enabling light path transmission and image acquisition in machine vision systems. Fiber optic light guides can be used to construct high-speed, high-resolution image transmission systems for medical imaging, robot vision, industrial inspection, and other fields. Machine vision fibers have a wide range of applications, including illumination, sensing, light path transmission, and image acquisition. The high flexibility, reliability, and high-temperature resistance of fiber optic technology make it widely used in the field of machine vision. Nanjing Hecho Technology provides reliable optical transmission solutions for machine vision systems. Companies in relevant industries are welcome to inquire.

High-intensity light transmitted through the optical fibers provides clear images, enabling accurate medical diagnosis. Fiber Optic Biosensors: Optical fibers can be used as biosensors to detect and monitor chemical components, biomarkers, or pathological changes within the human body. Fiber optic sensors utilize light scattering, absorption, or changes in light propagation characteristics to detect target substances, enabling early diagnosis and disease monitoring. Laser Therapy: Fiber optic lasers can be employed in medical treatments such as laser surgery, laser therapy, and photodynamic therapy. Laser light transmitted through optical fibers is directed to specific areas of the patient's body, achieving objectives like cutting, coagulation, vaporization, or irradiation of targeted tissues. Fiber Optic Spectroscopy: Spectroscopy is a technique used for analysis and diagnostics, and optical fibers can facilitate non-invasive spectroscopic measurements. By connecting optical fibers to spectrometers or microscopes, spectral information of samples can be obtained, allowing identification of substance composition, concentration, or tissue characteristics. Fiber Optic Imaging: Optical fibers find applications in medical imaging devices such as optical coherence tomography (OCT) and fiber optic microscopy. These technologies utilize fiber optic transmission and detection of light to generate high-resolution tissue images for disease diagnosis and research purposes. The applications of optical fiber in medical diagnostics not only provide more accurate and convenient diagnostic tools but also enable non-invasive and minimally invasive treatments, thereby significantly advancing and innovating the field of medicine.

High-temperature fiber optic cables are specially designed and manufactured optical fibers that exhibit excellent resistance to high temperatures. Conventional optical fibers may suffer damage or performance degradation in high-temperature environments, whereas high-temperature fiber optic cables can maintain good operational stability under extreme temperature conditions. High-temperature fiber optic cables are typically made with materials that have high melting points and low thermal expansion coefficients, such as high-silica materials or special coatings (such as polyimide coatings). These materials help preserve the structural integrity and transmission performance of the fiber optic cables at high temperatures. High-temperature fiber optic cables find wide applications, particularly in industrial, military, and research settings operating in high-temperature environments. For instance, they can be used for sensing, optical signal transmission, and laser connections in high-temperature furnaces, thermal power plants, aerospace applications, and more. The special design and manufacturing of Hecho high-temperature fiber optic cables enable them to deliver reliable performance in extreme temperature environments, providing crucial solutions for high-temperature application scenarios.

The concept of fiber bundles actually exists in a mineral material found in nature called ulexite. Ulexite is also as TV rock. Its end face has a fascinating structure, resembling densely packed fiber bundles. This complexly structured mineral contains chains of sodium, water, and hydroxide octahedra. It appears in the form of silky white circular clusters or parallel fibers. TV rock possesses unusual optical properties, where the parallel fibers act like fiber bundles, conducting light along their length through internal reflection. If a crystal is taken, cut into planes perpendicular to the direction of the fibers, and both surfaces are polished, the TV rock sample can display an image similar to what is seen on the opposite side, much like a fiber optic panel. Nature's design has inspired scientists' understanding of the world, and combined with human intelligence, it will continue to drive progress and development in the scientific community. Nanjing Hongzhao Technology offers customized fibers, including PCR fiber bundles, power delivery fibers, LDI laser fibers, and more.

Fiber optic is a slender light-conducting material made of high-purity glass or plastic that enables the transmission of light through internal reflection. In fiber optic transmission, light typically propagates along a straight path, but a series of optical phenomena occur when the fiber optic bends. Addressing fiber optic bending issues involves considering the following aspects: Choosing the appropriate type of fiber optic: When designing and installing a fiber optic network, it is possible to select fiber optic types that are suitable for bending. Flexible fiber optics usually have higher bend tolerance, allowing them to work on smaller radius curves without causing light loss. Therefore, choosing flexible fiber optic is an important step in reducing fiber optic bending issues. Controlling the fiber optic's bending radius: By controlling the bending radius of the fiber optic, it is possible to minimize bending loss. Generally, the larger the bending radius of the fiber optic, the lower the bending loss. During fiber optic cabling and installation, it is necessary to avoid excessive bending, particularly when the bending radius is smaller than the fiber optic's allowed bending radius. Proper equipment and techniques can be used, such as fiber optic bend protection sleeves and fiber optic strain relief devices, to ensure the fiber optic's bending radius is appropriate. Avoiding mechanical stress: Fiber optics are prone to mechanical stress in applications, such as tension, pressure, and twisting. These mechanical stresses can cause bending deformation and damage to the fiber optics, resulting in loss of light transmission. Therefore, during fiber optic cabling and installation, it is important to avoid applying mechanical stress and use suitable fiber optic protection devices and brackets to reduce the impact of mechanical stress on the fiber optic. Nanjing Hecho supports custom fiber optics, and by selecting the appropriate fiber optic type and controlling the fiber optic's bending radius, it is possible to effectively address fiber optic bending issues, improving the reliability and performance of fiber optic transmission, and meeting different customer usage requirements.

The power of lasers directly affects the interaction between lasers and the human body, and different laser wavelengths have different effects on biological tissues. The medical beauty market includes all lasers used in ophthalmology, surgery, dentistry, skin, hair, and other cosmetic procedures. In the well-known field of laser skin rejuvenation, the principle is to select lasers with a high absorption rate in human tissues, utilize their stimulating effect on biological tissues, and deliver fractional laser beams to the skin to create numerous micro-treatment zones. These micro-treatment zones are vaporized and receive thermal damage, initiating the skin's wound healing mechanism, allowing the regeneration of the epidermis, and promoting collagen synthesis in the dermis through thermal stimulation. Hongzhao specializes in the research and development of medical laser fibers, and related products have been extended to the field of medical beauty. They meet the requirements of various lasers, such as thulium lasers, holmium lasers, erbium lasers, and demonstrate great effectiveness in their applications.

In environments above 400°C, organic materials used for coatings quickly undergo thermal oxidation aging, resulting in the loss of protection for the fiber and rendering it unusable. To enable normal operation at higher temperatures, high-temperature resistant metal materials (aluminum/copper/gold) are tightly wrapped around the bare fiber. Benefits of using high-temperature resistant metals: Lower coefficient of thermal expansion (similar to the fiber's coefficient) Corrosion resistance Good fatigue resistance, water resistance, and hydrogen resistance High mechanical strength Extreme high and low-temperature adaptability Weldability Using aluminum extends the temperature range from -269°C to +400°C, while copper extends it from -269°C to +600°C. Gold can withstand temperatures from -269°C to +700°C. This type of fiber is used for ultra-longevity in harsh external environments and can also be used as components in electronic circuits. However, due to its complex manufacturing process and high cost, it is often only used in short segments where necessary. Note: The metal coating process is complex and has very low production efficiency. Stripping the metal coating cannot be done with wire strippers and requires methods such as heat-sulfuric acid fusion or nitric acid for stripping. The introduction above covers the three types of fiber metal coating materials. Quartz fiber is widely used in communication and non-communication fields due to its wide spectral range and low loss. However, it is necessary to select fibers with different coating materials based on the requirements of different applications, environments, and sectors.

Fiber doping techniques involve introducing specific materials, known as dopants, into the core of the fiber to modify its optical and conduction properties. This technique finds wide applications in fields such as fiber optic communications, fiber sensing, and fiber lasers. Here are some common fiber doping techniques: Rare-Earth Ion Doping: Rare-earth ions (such as erbium, neodymium, and terbium) are commonly used as doping agents in optical fibers. By introducing rare-earth ions into the fiber core, functionalities such as amplification, laser emission, and frequency conversion can be achieved within specific wavelength ranges. Rare-earth ion doping is crucial for improving the performance of fiber amplifiers and fiber lasers. Doping via Solution Soaking: This method involves dissolving the dopant material in an appropriate solvent and immersing the fiber into the solution, allowing the dopant to permeate the fiber core. Subsequently, heat treatment is applied to solidify the dopant within the fiber. This method enables localized doping of the fiber and allows control over the dopant concentration distribution. Vapor Phase Doping: This technique utilizes chemical vapor deposition during the fiber manufacturing process to introduce the dopant. Typically, the dopant material and the fiber's raw materials are simultaneously introduced into a reaction vessel. Through chemical reactions like thermal decomposition or desorption, the dopant reacts and adsorbs onto the fiber core, resulting in doped fiber formation. Ion Exchange Doping: In this method, ions are doped into the fiber core through ion exchange reactions. Typically, the fiber core material is silica (SiO2), while the dopant solution contains the desired ions. During the ion exchange process, the silicon ions in the fiber core are replaced by the dopant ions, thereby achieving doping. Through doping techniques, specific optical, conduction, or excitation characteristics can be imparted to fibers to meet various application requirements. The development of these techniques continually drives advancements in fiber optic communication and fiber technology.

The rod-in-tube (RIT) method is one of the conventional techniques used for optical fiber preform preparation. Interestingly, this term can also be found in other industries. In simple terms, it involves placing a glass rod inside a glass tube, heating the tube to melt it onto the rod, forming a thicker solid rod known as the optical fiber preform. Finally, one end of the preform is heated and stretched to form the optical fiber. RIT brings about various possibilities for specialty fiber development, and the tube-in-rod technique extends beyond the use in communication fibers. This technique enables more flexible fiber designs and paves the way for wider applications.
