Abstract
A planar micro lens array, in which a surface-relief micro lens array is built into the glass substrate using a stamping replication method, has been developed for parallel optical components. The planar micro lens array has completely flat surfaces on both sides, and therefore other parallel optical devices can be monolithically composed in tandem. Furthermore, a high thermal reliability for axial alignment is made possible by the adoption of the same material of the substrate as that of the others. In this paper, we review the fabrication method of this planar microlens array using a stamping replication method and discuss the advantages of its use with liquid crystal displays.
