Original Abstract Submitted
An optical imaging system includes a first lens group including a reflective member and one or two lenses disposed in front of the reflective member; and a second lens group disposed behind the reflective member and including a plurality of lenses. The one or two lenses included in the first lens group have a positive refractive power overall, an image-side surface of a lens disposed closest to the reflective member among the one or two lenses included in the first lens group is concave, the reflective member includes an incident surface, a reflection surface, and an exit surface, and 0.25≤D12P/DR≤1.0 is satisfied, where D12P is a distance on an optical axis from the image-side surface of the lens disposed closest to the reflective member to the incident surface, and DR is a distance on the optical axis from the incident surface to the reflection surface.
