Laser is one of the great inventions of mankind in the 20th century, and it is widely used in many fields. Laser medicine is one of the important branches. The laser is mainly used in the treatment of brain diseases, cardiovascular diseases, diabetes, malignant tumors, leukemia, psychiatric diseases, psoriasis, rhinitis and so on. According to the findings of health medicine, low-intensity lasers have good curative effects in the prevention of the onset of cardio-cerebral vascular disease and the recovery period after onset, and have a certain effect on health and inhibition of human aging. Laser transmission tools, such as rotary light-guiding arm and Laser Fiber, have been rapidly developed, such as the first fiber optic transmission laser in 1973, after Nath made a single Quartz Fiber capable of transmitting high-energy Ar+ lasers. With the advent of mirrors, Silica Fiber heads (spheroidal, granular, etc.) have been developed into various shapes to open the way for lasers to enter the lumen. In 1977, the United States developed a new type of far-infrared fiber, such as bismuth bromide, which was used in the clinical application of CO2 laser fiber. In particular, photodynamic therapy, that is, photosensitizing drugs combined with laser irradiation treatment, laser light sources have evolved from single He-Ne lasers to dye lasers, gold vapor lasers, Krypton (Kr+) lasers, and semiconductor lasers. The scope of photodynamic therapy, from malignant tumors, such as skin cancer, lung cancer, digestive tract tumors, bladder cancer, etc., also extends to the treatment of benign lesions, such as port wine stains, age-related macular degeneration and so on. In the past, laser beauty was limited to skin pigmentation and vascular lesions. It has now developed into cosmetic laser medicine. This is mainly due to Andersen’s “selective photothermal effect” theory in the 1980s, that is, according to different organisms. Learn characteristics, choose the appropriate wavelength, energy, pulse duration, to ensure effective treatment of diseased tissue, while avoiding damage to the surrounding normal tissue. The development of the above-mentioned high-intensity lasers vaporizes, cleaves, coagulates, and cauterizes the lesions of patients and develops them to selectively destroy lesions without damaging normal tissues and achieving therapeutic goals. Supports the production of special optical fiber, laser endoscopes and catheters for interventional treatment. Slit lamps for lasers, laser surgical microscopes, and all types of laser medical equipment required are supplied exclusively by manufacturers.

Color rendering refers to the objective effect produced by light emitted by a light source on an object and the degree of appearance of the true color of the object, which is an important indicator of the illumination light source. The light source with high color rendering performs better on the color, the color seen is close to the natural color, and the light source with low color rendering performs poorly on the color, and the color deviation seen is also large. If the light emitted by the light source contains a proportion of each color of light that is similar to natural light, the colors seen by the human eye are more realistic. The spectral distribution of the light source determines the color rendering of the light source. The color rendering of the light source affects the color of the object observed by the human eye. Quantitative evaluation of the color rendering property of the light source is an important indicator for evaluating the quality of the light source. General artificial lighting sources use the general color rendering index as an evaluation index of color rendering, and the color rendering index is also an important parameter to measure the color characteristics of the light source. According to different application fields, Nanjing Hecho Technology Co., Ltd. launched a new ultra-bright high color rendering index medical Endoscope Light Source Module; ultra-high brightness LED Cold Light Source, and Fiber Optic Illuminators and other products to meet the needs of different customers, welcome The majority of new and old customers to inquire.

The core is the central region where the refractive index of the transmitted light in the optical waveguide is higher than that of the adjacent region. For the step-type refractive index distribution fiber, the core is a cylinder containing a fiber core with a high refractive index. As the optical Fiber Optical Transmission layer called cortex, also known as cladding, for the step-like refractive index distribution fiber, the cortex is the lower refractive index of the ring outside the core, see the following figure. Optical fiber coating layer is coated with a layer of protective fiber material, referred to as fiber coating, also known as coating or buffer layer or fiber coating, optical fiber coating not only has to maintain fiber strength, to prevent fiber micro Bending loss and the ability to prevent fiber damp, but also reduce the mechanical damage of the fiber, and some fiber coating also has a specific physical variables sensitive to the characteristics can be used for sensing measurements, the typical coating materials, including acrylic resin, silicon Resin, ethylene-tetrafluoroethylene copolymer, polyurethane and polyimide, see the following figure. The cladding mode is a mold that is transferred and held in the fiber cortex. Usually, a cortical material that absorbs or attenuates the cladding mode is used to prevent the transition of the cladding module energy into a core, Thus reducing the dispersion, cladding mode, also known as cladding mode. Hecho specializing in manufacture Fiber Optic Cables, Fiber Optic Bundles, Fiber Optic Sensors, and Fiber Optic Illuminators for over 10 years. We supply a complete solution for Optical Fiber transmission. OEM service is welcome.

Optical fiber (referred to as fiber) has a lot of types. According to the materials used in the manufacture of optical fiber classification as Quartz Fibers, Multi-component Glass Fibers, and Plastic Optical Fibers. According to the light in the fiber transmission mode can be divided into: Single-mode fiber and Multi-mode fiber. Cross section Refractive index Light propagation Fiber types Multimode - step refractive index Single mode - step refractive index Multimode - gradient refractive index The optical fiber is classified on the one hand according to the refractive index distribution of the core profile, and on the other hand, according to the number of patterns transmitted. As described above, it is divided into single-mode optical fiber and multimode optical fiber. According to the profile refractive index distribution is divided into step optical fiber, gradient refractive index optical fiber and special profile refractive index distribution optical fiber. Step Refractive index The refractive index of the optical fiber over the entire cross section is constant. Gradient Refractive Index The optical fiber cross section is non-linear, rotationally symmetric, and the refractive index decreases from the center to the edge. Step Refractive index The refractive index of the multimode optical fiber is constant, so its distribution index g = α. Gradient Refractive Index The refractive index of the optical fiber decreases from the center to the edge. The light travels along the axis of the optical fiber, rather than straight.
