Abstract

PCT No. PCT/CH79/00074 Sec. 371 Date Jan. 23, 1980 Sec. 102(e) Date Jan. 17, 1980 PCT Filed May 23, 1979 PCT Pub. No. WO79/01106 PCT Pub. Date Dec. 13, 1979.An optical fiber has an end face adjoining the flat side of a plano-convex microlens of spherical curvature made from thermoplastic material. The microlens, overlying at least the entire cross-sectional area of the fiber core at that end face, is produced by juxtaposing a substantially spherical microball with that end face, heating the microball-preferably by a pulsed laser beam-to a temperature at which it deforms and spreads over the fiber face, and letting it cool. Also disclosed is an optimum numerical relationship between the radius of curvature of the convex surface of the microlens and the distance of its apex from a virtual point source, such as a laser, illuminating that microlens with a divergent beam.
