Original Abstract Submitted
An optical system includes a first transmissive reflective surface, a second transmissive reflective surface located closer to an image than the first transmissive reflective surface, and a lens located closer to an object than the first transmissive reflective surface or closer to the image than the second transmissive reflective surface. The first transmissive reflective surface is configured to move in an optical axis direction during focusing. The lens is separated from each of the first transmissive reflective surface and the second transmissive reflective surface.
