Fiber for Intravascular Irradiation XGZS-07
Intravascular irradiation fibers are tools in interventional radiology, cardiology, and vascular surgery for treating/diagnosing vascular and cardiac diseases. They deliver light to specific vessel regions for treatment, such as opening blockages, or diagnosis, such as hemodynamic assessment. Blood contains cholesterol, triglycerides, and other lipids; excess of one or more is hyperlipidemia, often from excess intake, metabolic disorders, or secondary elevation due to diabetes or thyroid disease. The source describes “low-andu” lipoprotein cholesterol entering beneath the intima and forming atherosclerotic plaques, narrowing or occluding arteries. Lipids also coat red cells, reducing oxygen/nutrient carrying and causing hypoxia; increased viscosity and thrombi block vessels, causing ischemia, nutrient deprivation, and necrosis in “yiji” (source wording), brain, lungs, lower limbs, and other sites, leading to coronary disease or cerebral infarction. Low-intensity semiconductor-laser irradiation is described as converting light to biological internal energy, regulating the internal environment, lowering viscosity, improving red-cell deformability/nutrient carrying, improving microcirculation, activating enzymes, stimulating adrenal cortex and glucocorticoids, reducing intrahepatic “shicheng cholesterol lipoproteins” (source wording), accelerating triglyceride dissolution and lipoprotein breakdown to lower lipids. Low-intensity lasers produce biostimulation without direct irreversible target injury. The source states that they promote diseased tissue normalization and stronger vital activity without damage. Irradiation activates blood enzymes and red cells, increasing internal energy and enzyme activity, changing hemorheology and circulation/microcirculation, improving toxic symptoms, regulating immunity, and treating disease. Devices generally use disposable sterile fibers ending in fiber needles with 2-4mW output and approximately 74mm length.

Beveled Fiber Lens Optical Fibers Raysung
Beveled fiber lenses mainly fall into two categories. One has bevel angles of 6°～10° to prevent surface-reflected light from causing interference or damage on its return path. The other has angles of 40°～50° or greater, changing the optical path or producing large-angle total reflection. It can also increase the fiber's light-receiving area to admit more light. Main applications include fiber lasers, fiber-optic communications, conventional optics, and fiber sensing.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
