Controlled injection of fluid into a flexible lens chamber has previously produced tunable spherical lenses with spherical aberration problems. This paper presents a novel fluidic-controlled meniscus/biconvex lens system with relatively low distortion. The lens fabrication method is described and manufactured lenses are characterized for different processing parameters. Images captured through one of our lenses for a range of different pressures are presented. A change in focal length of five times (19.1-80.8 cm) is demonstrated. The focal length shows a quadratic relation to the applied pressure (0-5 kPa). For the simple prototype lens, distortion is less than 5% and relative illumination is above 0.74 by ZEMAX analysis.
此前，向柔性透镜腔中控制性地注入流体已制造出存在球差问题的可调谐球面透镜。本文提出了一种具有相对低畸变的新型流体控制弯月面/双凸透镜系统。描述了透镜制造方法，并对制造出的透镜针对不同加工参数进行了表征。展示了通过我们的其中一个透镜在一系列不同压力下拍摄的图像。证明焦距有五倍的变化（19.1 - 80.8厘米）。焦距与施加压力（0 - 5千帕）呈二次关系。通过ZEMAX分析，对于简单的原型透镜，畸变小于5%，相对照度高于0.74。
