Abstract

　コンパクトで、十分な明るさを備えた結像光学系を提供する。３枚の反射鏡を備え、視野中心の光軸をＺ軸とするＸＹＺ直交座標系を定めた場合に、ＹＺ断面において光軸の向きを変化させ、第２反射面に入射する光路と第３反射面から射出される光路とが交差し、視野中心の光軸と像面の光軸とが平行となる。反射面の少なくとも一つが回転非対称面である。視野中心の光軸に沿った光線の光路に沿って、第１反射面と第２反射面間の距離をＬ１、第２反射面と第３反射面間の距離をＬ２、第３反射面と像面間の距離をＬ３、第１反射面と像面間の距離をＬとし、第１反射面のＸＺ断面の焦点距離をｆｘ１、第１反射面のＹＺ断面の焦点距離をｆｙ１、等価エフナンバーをＦｎｏとして、 　-60< fy1/L3 <0 　-60< fx1/L3 <0 　0.635< Fno (L2/L3) <1.12 　0.35 < L1/L <0.5 が満たされる。
