WebConvex lenses are used in photocopiers. A concave lens is one that bends a straight light beam away from the source and focuses it into a distorted, upright virtual image. Both actual and virtual images can be created using it. At least one internal surface of concave lenses is curved. 0 Download BYJU'S The Learning App WebWe study the theoretically data based on transparent VHB material coupling hydrogel electrodes, and present the transparent DEA that drives focus lens system. Computational results show basic characteristics of the DEAs for lens. When a voltage is applied to the fabricated lens module, optical focal length changes with the voltage.
