PROBLEM TO BE SOLVED: To provide an optical system and an observation device having high resolution at a large screen, capable of excellently correcting astigmatism in an entire wide imaging area, suppressing image degradation, and allowing a smooth search and local observation of a subject.SOLUTION: An optical system includes: an imaging optical system configured to image an object; a re-imaging optical system configured to re-image the object imaged by the imaging optical system; and a drive mechanism configured to rotate an optical element included in the re-imaging optical system around an optical axis of the re-imaging optical system.SELECTED DRAWING: Figure 1 【課題】大画面で高い解像力を有し、広い撮像領域の全域で良好に非点収差を補正可能であり、画像劣化を抑制し、スムーズに被写体の探索および局所観察を可能にする光学系および観察装置を提供すること。【解決手段】物体を結像する結像光学系と、結像光学系により結像された物体を再結像する再結像光学系と、再結像光学系を構成する光学素子を、再結像光学系の光軸回りに回転させる駆動機構と、を有する。【選択図】図１
