A lensed fiber includes an optical fiber and a lens formed at a distal end of the optical fiber. The lens has a minimum diameter determined by 2.T.tan(.theta.), where .theta. = n.sin-1(NA) , T is thickness of the lens, n is index of refraction of the lens, and NA is numerical aperture of the optical fiber.

Cette invention concerne une fibre à lentille comprenant une fibre optique et une lentille à l'extrémité distale de cette dernière. La lentille présente un diamètre minimum déterminé par 2.T.tan(?), dans laquelle ? = n.sin?-1¿(NA)? ¿, T est l'épaisseur de la lentille, n est l'indice réfraction de la lentille et NA l'ouverture numérique de la fibre optique.
