Controlled volume transfer and lens shape formation by liquid bridge disconnection

A liquid bridge was created and disconnected to transfer a controlled volume of mixture to a cylindrical post for the formation of parabolic lens shapes. We investigated a transferred volume and the focal length of the lens shape in terms of four parameters: post radius, withdrawal speed, dipping de...

Description
Summary:A liquid bridge was created and disconnected to transfer a controlled volume of mixture to a cylindrical post for the formation of parabolic lens shapes. We investigated a transferred volume and the focal length of the lens shape in terms of four parameters: post radius, withdrawal speed, dipping depth, and mixture thickness. The presented method is simple and flexible to transfer a pre-analyzed volume and subsequently to fabricate a lens shape on post structures, which can be beneficial to implementing self-aligned and smooth lenses integrated in micro structures.
