    • A lens with a variable focal length is provided to increase the change rate of the focal length by increasing the maximum rotational angle of a micromirror so as to obtain the great change of a numerical aperture. A lens(11) with a variable focal length has a plurality of micromirrors(13) with one degree of freedom of a rotational motion and one degree of freedom of a translational motion. A reflecting surface of the micromirror is made of metal, metal alloy, multi-layer dielectric coating, or materials with high reflectivity. Each degree of freedom of the rotational and translational motions of the micromirror is controlled to change the focal length of the lens and satisfy the same phase condition of the light. The diffractive Fresnel lens is used.
    • 提供具有可变焦距的透镜,通过增加微镜的最大旋转角度来增加焦距的变化率,从而获得数值孔径的大的变化。 具有可变焦距的透镜(11)具有多个具有旋转运动的自由度和平移运动的一个自由度的微镜(13)。 微镜的反射面由金属,金属合金,多层电介质涂层或具有高反射率的材料制成。 控制微镜的旋转和平移运动的每个自由度以改变透镜的焦距并满足相同的光的相位条件。 使用衍射菲涅尔透镜。
