Wedged lensed fiber and tapered lensed fiber
The collimation and beam shaping at the end of optical fiber systems has a big impact on system performance. The increase of the coupling efficiency between light sources for many applications in communication engineering and medical technology fibers and detectors, the adaptation of the radiation characteristics of endoscopic instruments as well as the improvement of the properties of fiber optical sensors are results of the integration of micro optics. The combination of external optical components on the fiber tip or directly in front of the fiber exit needs high alignment accuracy and small mounting tolerances. A promising alternative is the manufacturing of micro lenses directly onto the fiber ending. The reduction of the number of optical interfaces reduces optical losses and eases alignment of the system. Adhesion problems caused by thermal or mechanical stress are eliminated.
RaySung employs 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 can manufacture lensed fiber into a variety of different shapes that include oblique wedge-shape, wedge-shape, cone-shape and spherical. Metallic coating and FC packaging can also be applied. The physical dimensions of the lensed fiber are controllable with more than 80 percent coupling efficiency possible. RaySung's equipment is uniquely designed in-house, enabling the company to improve on any design to meet the most demanding customer requirements. 
Applications of Lensed fiber:
• Active component pigtailing
• DWDM devices
• Waveguide packaging
• MEMS device connections
• Miniaturized fiber optic components
• Coupling to circular or elliptical beam outputs
