Title:
MANUFACTURING METHOD OF LENS MOLD
Document Type and Number:
Japanese Patent JP2007112134
Kind Code:
A
Abstract:
To provide a rational manufacturing method of a lens mold suitable for manufacturing a lens area.
When spheres are fully tightly arranged in a hexagonal housing part, a group of spheres spontaneously becomes a hexagonal lattice structure. Therefore the housing part can be completely filled with spheres to be shaped. Since the housing part 20 has a hexagonal cross section and the small spheres 22 are tightly mounted, the small spheres 22 can be arranged correspondingly to the hexagonal lattice structure. The small sphere 22 has a radius substantially corresponding to the radius of a micro lens 8 to be manufactured, and the small sphere 22 can be tightly housed in the housing part 20.
