(JA) マイクロレンズアレイ及びその製造方法並びに光学装置
Abstract: front page image
(EN) PROBLEM TO BE SOLVED: To provide a method for manufacturing a microlens array wherein the alignment of both lens surfaces is simple, the microlens array manufactured thereby and an optical device.

SOLUTION: The method for manufacturing the microlens array includes a process for forming a second light pervious layer 36 on a first light pervious layer 26. The first light pervious layer 26 has a plurality of recessed parts 28 and the demarcation surfaces 32 of the recessed parts 28 and at least a part of the inner surface of each of the recessed parts 28 is a lens surface 30. The second light pervious layers 36 are formed to the recessed parts 28 so as to avoid the demarcation surfaces 32 of the first light pervious layer 26. The surfaces of the light pervious layers 36 are formed so as to have lens surfaces 38 at every recessed part 28.
