Imaging device

摘要

An imaging device includes a first focusing element on which rays from an object are incident, a second focusing element from which the rays are emitted toward an imaging surface, and a roof mirror having surfaces which are connected to each other at an angle of 90 DEG so that a ridge line is formed, the roof mirror being arranged so that the ridge line intersects optical axes of the first focusing element and the second focusing element at a position on a plane including the optical axes.
