Title:
LENS ARRAY AND METHOD FOR FABRICATING THE SAME
Document Type and Number:
WIPO Patent Application WO/2011/125341
Kind Code:
A1
Abstract:
Provided is a lens array that can be simply modularized at low cost while optical performance can be ensured. When a lens array main body (18) is formed by means of a three-dimensional shape comprising a first weld control concave part (22) and a second weld control concave part (23), a flow passage is formed in the center of a molten resin material between the first and second weld control concave parts (22, 23), so that a stream of the molten resin material flowing in the center merges with a stream of the molten resin material which branches at the position where a first lens surface (11) is formed and then attempts to flow to the position where the first lens surface (11) is formed from an outer side flow passage located apart from said position where the first lens surface (11) is formed.
