    • A focus adjustment method of a zoom lens system is provided for correcting a focal point shift caused by manufacturing error. The zoom lens system includes three movable lens groups in which at least two of said lens groups are moved to perform zooming to form an image onto an imaging device. In the zoom lens system, a finite number of focal length positions at which a focus adjustment is performed is provided. The lens group closest to the imaging device out of the three lens groups includes a focusing lens group. A position of the focusing lens group is controlled via pulses of a stepping motor. The focus adjustment method includes the combination of performing the above control of the focusing lens group to determine a position of the focusing lens group via pulses of the stepping motor and determining an amount of adjustment of the imaging device.
    • 提供了一种用于校正由制造误差引起的焦点偏移的变焦透镜系统的焦点调节方法。 变焦透镜系统包括三个可移动透镜组,其中至少两个所述透镜组被移动以执行变焦以在成像装置上形成图像。 在变焦透镜系统中,提供执行焦点调整的有限数量的焦距位置。 在三个透镜组中最靠近成像装置的透镜组包括聚焦透镜组。 通过步进电机的脉冲控制聚焦透镜组的位置。 焦点调整方法包括执行聚焦透镜组的上述控制的组合,以经由步进电机的脉冲确定聚焦透镜组的位置,并确定成像装置的调整量。

    • A zoom lens system includes a negative first lens group, a positive second lens group, and a positive third lens group. Upon zooming from the short focal length extremity to the long focal length extremity, each of the first to third lens groups move along the optical axis. The first lens group includes a negative first sub-lens element, a second sub-lens element having a weak negative refractive power and at least one aspherical surface, and a positive third sub-lens element. The zoom lens system satisfies the condition, 0.5
    • 变焦透镜系统包括负第一透镜组,正第二透镜组和正第三透镜组。 当从短焦距末端变焦到长焦距末端时,第一至第三透镜组中的每一个沿着光轴移动。 第一透镜组包括负的第一子透镜元件,具有弱的负折光力的第二子透镜元件和至少一个非球面,以及正的第三子透镜元件。 变焦透镜系统满足0.5 <(ra-rb)/(ra + rb)<1.2(1)的条件,其中ra表示第二子透镜元件的物体侧表面的曲率半径,rb表示 第二子透镜元件的图像侧表面的曲率半径。
