A
Abstract:
To provide a method for manufacturing a resin erect lens array by means of injection molding.
In this method for manufacture, a metal plate 10 with a substantially parallel and flat surface is prepd. and concave dents 14 are formed by mechanical processing based on NC control on the surface of the metal plate 10.
