Lensed fiber, also called fiber lens, is a piece of fiber which forms a lens shape at the end face, and is used to change the optical path, or coupling light in the optical fiber systems. Based on the specific requirement of different applications, there are tapered, wedged, angle wedged, beveled, and spherical lens, etc.
Raysung applies the most advanced mechanical processing method in the world for manufacturing lensed fiber. The company's cutting-edge technology holds independent intellectual property protection. Raysung is capable of manufacturing lensed fiber into different shapes. The geometrical parameters can be well controlled in order to reach the best performance. AR Coating and metallization are also available.
