Beveled lensed fibers are mainly divided into two types: one is 6°～10°, which is used to prevent interference or damage caused by reflected light from the surface of the fiber when returning to the optical path, the other is 40°～50° or even Larger, this kind of beveled lensed fiber can change the optical path and even cause a large-angle, total reflection of the optical path, and can also increase the light-receiving area of the optical fiber so that more light enters into the optical fiber.

Mainly application is used in fiber laser, fiber communication, traditional optics, fiber sensing and other fields.
