A new type of solid-state variable focal length lens is described. It is based on shape changes in an elastomeric membrane driven by compression of a reservoir of a polymer gel. A novel fabrication process based on individual lens components allows for customization of lens power based on the desired application. The lens shape as a function of applied compressive strain is measured using direct surface profile measurements. The focal length of a solid state lens was reversibly changed by a factor of 1.9. Calculated back focal lengths of the lens were consistent with experimental measurements.
描述了一种新型的固态可变焦距透镜。它基于由聚合物凝胶储液器的压缩驱动的弹性体膜的形状变化。基于单个透镜组件的新颖制造工艺允许根据所需应用定制透镜焦度。使用直接表面轮廓测量来测量作为施加压缩应变函数的透镜形状。固态透镜的焦距可逆地改变了1.9倍。计算得到的透镜后焦距与实验测量结果一致。
