Title:
IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/200008
Kind Code:
A1
Abstract:
Provided is an imaging device capable of suppressing the deterioration in the optical performance of a lens array stack due to a change in the ambient temperature and enabling highly accurate imaging. First to third lens arrays (10, 20, 30) constituting the lens array stack are formed of a resin material using a molding die, and thus the lens arrays (10, 20, 30) tend to warp due to the influence of temperature. However, the lens arrays (10, 20, 30) are bonded at the supports (10b, 20b, 30b) between the adjoining lenses (10a, 20a, 30a) via spacers (40, 50) as coupling members, and thus it is possible to reduce the warping of the lens array stack (200) and suppress local degradation in the image-forming performance of a compound-eye optical system (100), thereby enabling highly accurate imaging.
