Abstract:
An optical system includes two imaging optical systems, each imaging optical system including a reflective optical element having a reflecting surface and a held part at a different position from the reflecting surface, the reflecting surface configured to reflect light incident from a subject side; a first holding body configured to hold the held part of the reflective optical element of one of the imaging optical systems; and a second holding body configured to hold the held part of the reflective optical element of the other one of the imaging optical systems. When the first holding body is combined with the second holding body, the reflecting surface of the reflective optical element of the one of the imaging optical systems is opposed to the reflecting surface of the reflective optical element of the other one of the imaging optical systems.
