定日镜 将太阳或其他天体的光线反射到固定方向的光学装置，又称定星镜。作用与定天镜类似，但采用一块平面镜置于赤道式装置中，可作赤纬方向的移动。当镜面以周日运动的速度作跟踪运动时，太阳光或星光被反射到极轴方向，然后直接或经辅助平面镜反射入固定的望远镜。与定天镜相比，它的主要优点是不用导轨，结构简单紧凑。光线入射角在跟踪过程中变化很小，一天以内仪器偏振近于常数，有利于太阳表面磁场横向分量的测量。主要缺点是反射天区(即视场)以周日速度旋转，观测有视面天体时，需补偿这种视场旋转。此外，由于冬季太阳光入射角较大，因此对镜面精度的要求比定天镜更高。美国基特峰天文台的太阳塔，采用的口径二米的定日镜是世界上最大的。它还用于观测恒星和行星的光谱。（见彩图）
