LENS ARRAY, MANUFACTURING METHOD OF LENS ARRAY, ILLUMINATION OPTICAL DEVICE, AND PROJECTOR
摘要:
Molten glass (G) is set and press-molded in a molding die (60) having dies (621A1, 621A2) corresponding to a lens array. After the molding, the molded article is removed from the molding die (60) and separated by bending at a bend-separation face (121C), which is a boundary part of adjacent lens arrays, so that two lens arrays are produced.
