    • A macrolens comprising a first biconvex lens component, a second lens component consisting of a first positive lens element having the convex surface on the object side and a first negative lens element cemented to the first positive lens element, a third lens component consisting of a second negative lens element having the convex surface on the image side and a second positive lens element cemented to the second negative lens element and a fourth biconvex lens component. This macrolens has favorably corrected aberrations over the magnification range from 4 fold to 16 fold and such very bright field of view as F:2.0.
    • 包括第一双凸透镜部件的宏观光学元件,由物体侧具有凸面的第一正透镜元件和胶合于第一正透镜元件的第一负透镜元件构成的第二透镜部件,由第二透镜元件 在图像侧具有凸面的负透镜元件和与第二负透镜元件接合的第二正透镜元件和第四双凸透镜部件。 该倍增物在4倍至16倍的放大倍数范围内具有良好的校正像差,并且具有如F:2.0的非常明亮的视场。
