Abstract: The present work reports the design of micro lens for miniature cameras using COMSOL 4.3. The contact angle over the lens are obtained by electro-wetting effect, this effect can be understood in terms of forces. When the voltage (force) is applied, the wetting effect alters the focal length of lens as variance of contact angle of the lens. The two immiscible fluids were taken for fluid-fluid and wall-fluid interfaces to obtain boundary properties and contact angle over the lens respectively. The world is integrated by the electro-wetting lens due to their reliable properties. Finally, the analyses of the results would help us in selecting better design to get optimum focal length for given inputs among all the proposed designs and the concept shown in this paper can be open to various designs and also applicable for real time applications
