複眼光学機器
Document Type and Number:
Japanese Patent JP6422224
Kind Code:
B2
Abstract:
The multi-lens optical apparatus includes multiple imaging optical systems configured to respectively form optical images of an object in mutually different areas on an image plane. The multiple imaging optical systems include imaging optical systems having mutually different focal lengths, and adjacent lenses included in the multiple imaging optical systems are integrally held, the adjacent lenses being mutually adjacent in a direction orthogonal to optical axes of the multiple imaging optical systems. Of the multiple imaging optical systems, a most wide-angle imaging optical system whose focal length is shortest includes a most object-side lens that is a meniscus lens having a negative optical power and having a convex surface toward an object side, and the convex surface is disposed at a most object-side position in the multiple imaging optical systems.
