An adaptive liquid lens actuated by a photo-polymer is demonstrated. The lens cell consists of a top glass substrate and a bottom plastic slab with two holes: reservoir hole and lens hole, which are sealed with elastic membranes. A photo-sensitive polymer is attached to the membrane of the reservoir hole. Under blue light irradiation, the polymer is bent which exerts a pressure to regulate the curvature of the membrane on the lens hole and then change the focal length of the plano-convex lens. The focal length is tunable from infinity to 21.2 mm in seconds. Non-mechanical driving, easy integration with other optical components and compact system are the key features of this lens.
展示了一种由光聚合物驱动的自适应液体透镜。透镜单元由顶部玻璃基板和底部塑料板组成，底部塑料板有两个孔：储液孔和透镜孔，它们用弹性膜密封。一种光敏聚合物附着在储液孔的膜上。在蓝光照射下，聚合物弯曲，从而施加压力来调节透镜孔上膜的曲率，进而改变平凸透镜的焦距。焦距可在数秒内从无穷大调节到21.2毫米。非机械驱动、易于与其他光学元件集成以及系统紧凑是该透镜的关键特性。
