Abstract
An attachment optical system, to which an imaging lens is attachable on an object side of the attachment optical system includes two bending optical systems arranged in parallel. Each of the two bending optical systems includes a first reflective member and a second reflective member. Each of the two bending optical systems includes, in order from the object side to an image side, a front unit and a rear unit, which are separated by a maximum air gap on an optical axis in each bending optical system. At least one of the first reflective member and the second reflective member is disposed between a surface having refractive power and disposed closest to an object in the rear unit and a surface having refractive power and disposed closest to an image plane in the rear unit of each bending optical system.
