C-Lens design of special materials, has a special wedge surface, subject to direct specifically designed for fiber-learning. This micro-lens can be subject to a single straight beam shuttle fiber transmission, insertion loss is smaller; in turn, it will be used as a coupler coupled to the collimated beam inside the fiber. C-Lens for different working distance of collimator design, especially the long working distance. New three R & D department to design Jie different specifications of C-Lens.
