The second optical system forms an intermediate image at a position conjugate to the reduction side imaging surface, and the first optical system re-forms the intermediate image on the magnification side imaging surface. The second optical system consists of, in order from the magnification side, a first positive lens, a cemented lens having a positive refractive power as a whole, and a second positive lens. The cemented lens includes one negative lens and one positive lens."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Imaging optical system, projection display device, and imaging apparatus","description":"The imaging optical system consists of, in order from the magnification side, a first optical system and a second optical system.
