ABSTRACT:
Apparatus is disclosed for mounting an imaging lens array formed of a plurality of gradient index optical fibers onto a print head having a linear array of light sources, such that the optical fibers are accurately spaced from and aligned with the light sources. The apparatus includes attachment means for totally constraining one end of the imaging lens array relative to the print head and for constraining the other end of the imaging lens array to inhibit movement of the lens in two directions, while permitting at least limited relative movement between the imaging lens and the print head in a direction along the length of the light source array to accommodate different rates of thermal expansion of the imaging lens array and of the print head.
