Abstract
The present invention relates to a lens array unit fabrication process. A lens array forming step produces a first and a second lens arrays each having linearly-arranged first or second lenses. In a lens array connecting step, the first array is connected to the second array so that the first lenses are axially aligned with the second lenses. The connecting step includes providing of ultrasonic vibration by e.g. an ultrasonic horn. In the forming step, a resin casting is used in which lens array regions, each including linearly-arranged first or second lenses, are integrally formed in a direction perpendicular to the rows of lenses. In the forming step, a multiple-blade rotary cutter, provided with rotary blades disposed at a pitch corresponding to the transverse dimension of each lens array region, is used to simultaneously make cuts flanking the lens array regions.
