Abstract: The present invention relates to A fiber exit Element (1, 2) having A plurality of glass fibers (1), each having at least one core (11), which is each designed to guide A signal light radiation (A), and to at least one optical Element (2), preferably an optical window (2), an optical lens (2), an optical beam splitter (2), an optical prism (2) or an optical lens array (2), which is respectively connected and designed to receive the signal light radiation (A) from the open ends of the cores (11) of the glass fibers (1) and to discharge them as exit radiations via at least one exit surface (26), wherein the open ends of the cores (10) of the glass fibers (1), preferably further the open ends of the cores (10), are arranged within the material of the optical Element (2), preferably in relation to an entry surface (21) of the optical Element (2), and wherein at least the material of the open ends of the cores (11) of the glass fibers (1) is fused to the material of the optical Element (2).

Abstract: The present invention relates to a glass fiber (1) comprising at least one fiber core (10), at least one fiber cladding (11) which at least substantially encloses the fiber core (10) in the circumferential direction (U) and along the longitudinal axis (X), and at least one fiber coating (12) which substantially encloses the fiber cladding (11) in the circumferential direction (U) and along the longitudinal axis (X), wherein the glass fiber (1) has at least one first exposed portion (13a) where the fiber cladding (11) is exposed by the fiber coating (12), for removing light (B) at least from the fiber cladding (11), wherein at least the fiber cladding (11) has a plurality of recesses (14) at least substantially in the radial direction (R), which recesses are designed to at least partially discharge the light (B) at least from the fiber cladding (11).

Abstract: The present invention relates to a fiber exit element (1), comprising: a plurality of glass fibers (10) each having at least one core (10a) which is designed to guide a signal light ray (A); and at least one optical element (14), preferably an optical window (14), an optical lens (14), an optical beam splitter (14) or an optical prism (14), which is connected to each open end (11) of the cores (10a) of the glass fibers (10) and is designed to receive the signal light ray (A) from the open ends (11) of the cores (10a) of the glass fibers (10) and to output said signal light ray to the outside via at least one exit face (14b) as exit rays (A?).
