Beveled Fiber Lens
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.
