A plurality of gradient index optical fibers are assembled into a lens array by first providing each fiber with a coating of an inter-fiber light absorbent medium to a first thickness, followed by a second step of pressing the coated fibers into a mold by conventional pressing methods. The inter-fiber spacing is thus the sum of twice the coating thickness plus the ultimate gap between each pair of coated fibers.
