Liquidlens technology can easily perform more than 100 million cycles without any performance loss. Liquid lens structure the lens has a simple structure. With 20 years of growth, development and partnership to draw upon, liquid lens is the market leader for quality doming resin, doming technology and domed label production, and were still innovating. Unlike the liquid lens, conventional lens technology requires mechanical adjustments in order to focus or enlarge the images, being captured.
To determine the combined focal length of the lens system school. In this research, students can learn about the liquid lens by demonstrations and design the experimental apparatus for study. They incorporate all necessary electronic components to drive the liquid lens, and only require a dc power supply. The mixture of water and oil is sandwiched between two pieces of clear glass or plastic.
