Patent number: 10416422Abstract: A zoom lens forms an intermediate image at a position conjugate to a reduction side imaging plane and forms the intermediate image again on a magnification side imaging plane. The zoom lens includes a first optical system on the magnification side, and a second optical system on the reduction side. The intermediate image is formed between the magnification and reduction sides. The second optical system includes two or more movable lens groups, which move by changing spacings between the groups adjacent to each other in a direction of an optical axis during zooming, and two stationary lens groups which remain stationary with respect to the reduction side imaging plane during zooming. One stationary lens group is disposed closest to the reduction side, and has a positive refractive power. Also, a lens group closest to the magnification side in the second optical system has a positive refractive power.Type: GrantFiled: August 28, 2017Date of Patent: September 17, 2019Assignee: FUJIFILM CorporationInventors: Yukiko Nagatoshi, Kazuki Inoue, Akiko Nagahara
