| description | PROBLEM TO BE SOLVED: To provide an optical device that can stably correct the displacement of the optical axis.SOLUTION: An illumination optical system 10 of a projector being an optical device includes a light source device 1 comprising a discharge lamp 11 and a reflector 12 reflecting the light radiated from the discharge lamp 11 and emits the reflected light in a fixed direction. Into the path of the light emitted from the reflected 12, a cylindrical lens 9 (optical lens) can be inserted for correcting the displacement of the optical path resulting from the displacement of a light-emitting position due to a change in the lighting attitude of the discharge lamp 11.
【課題】安定的に光軸のずれを補正することが可能な光学装置を提供する。【解決手段】光学装置であるプロジェクタの照明光学系１０は、放電ランプ１１および当該放電ランプ１１が発した光を反射して一定の方向へ出射するリフレクタ１２とからなる光源装置１を備えている。リフレクタ１２が出射した光の経路には、放電ランプ１１の点灯姿勢の変化による発光位置のずれに起因する光路のずれを補正するシリンドリカルレンズ９（光学レンズ）が挿入可能となっている。【選択図】図７ |
