Abstract

Various methods of manufacturing are reviewed for large area (6 inch diameter and greater) microstructured optical components that are used for light management in non-imaging applications. All of the manufacturing methods discussed will relate to the processing of various optical grade polymers. This paper will start with a review of the traditional methods used to make plastic Fresnel lenses over the past forty or more years. The evolution of precision compression molding will be analyzed. Quality/cost trade-offs of the various methods currently used to produce large-area, thin cross-section, microstructured optical components will be discussed. Examples of products made by compression molding, transfer molding, hot stamping, thermal and UV casting and other various processing methods will be discussed. The paper will conclude with a look into the future. Where is non-traditional, non- glass optical component manufacturing technology headed?
