Abstract

© 2016 IEEE. An optical microscope is the primary equipment enabling us to see objects down to microscale level by human's naked eyes. In this talk, we discuss an approach to form an aspheric shape objective lens made of transparent adhesive polymer through gravity and surface tension. We tested imaging performance of such lenses and found that the total magnification exceeded 100x for instantly used liquid lenses, and was more than 450x for solid polymer lens. The shape of the lenses formed by the method is parabolic shape, which provides very good imaging performance.
