Abstract

Microlenses are widely used as components of optical device in LCD display, optical interconnection, scanner and others. It is important to fabricate microlens in any kind of form to satisfy any requirement of optical device. Also, the integration of microlens and optical devices is required to save weight, reduce production cost, and get higher accurate alignment. We have developed a novel method to fabricate spherical plastic microlens using Er:YAG laser beam. In this method, laser beam are shot to the surface of an acrylate resin to form microlens on this surface. In this paper, a method to fabricate cylindrical plastic microlens is proposed. Microlenses are fabricated under several conditions, and the influences of process parameters to geometry of microlens will be discussed.
