Abstract

Abstract: Polystyrene (PS) micro-cubic poles array was fabricated with the micro-molding of the soft lithography. Based on that the principle of liquid or melting matter will be the most stable state by means of reducing its surface energy to minimum, the PS micro-cubic poles array shrunk into the micro-hemispheroid array through the heating to the temperature over PS softening point. The optical imaging testing indicates that the PS micro-hemispheroid array had a good optical behavior of being able to image the “H” or “Y” type objects and could be used as micro-lens array. The microfabrication technology to fabricate polymer micro-lens array is easy and low-cost with a high precision and can be suitable for other transparent plastics. In addition, due to flexibility of PDMS stamp the micro-lens array would be possible to fabricate on a curved surface.
