Title:
COMPOUND EYE OPTICAL SYSTEM, IMAGE CAPTURE DEVICE, AND METHOD FOR PRODUCING COMPOUND EYE OPTICAL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/119737
Kind Code:
A1
Abstract:
Provided are: a high-resolution, ultrathin compound eye optical system that is lightweight and capable of ensuring a reduction in cost due to a simple molding; and a method for producing the compound eye optical system. In the case of a side gate in which a resin injection part (14) is positioned on a side of a lens array (10), the lens array (10) sometimes warps slightly in the direction of the gate. In the case of the compound eye optical system (100), equivalent performance is demanded in lens arrays (10, 20, 30) that are substantially the same size, therefore, molding conditions etc. are similar, and the direction and magnitude of warp are similar in the plurality of lens arrays (10, 20, 30). At that time, as described above, when gates (GA), in other words, resin injection parts (14, 24, 34) are aligned in the same direction and the lens arrays (10, 20, 30) are stacked on one another, the warps of the lens arrays (10, 20, 30) align, making it difficult for problems such as interval variations and eccentricity of lens elements (10a, 20a, 30a) due to differences in the warps of the lens arrays (10, 20, 30) to occur.
