Paper Abstract

Recently, the global applications of aspheric lens are expanding rapidly on the electronics, optical components, communications, aerospace, defense, and medical optics devices, etc. F-Theta lens, which is one of major applications of aspheric lens, is a core optical part in Laser Scanning Unit (LSU) because it mainly affects the optical performance of LSU. F-Theta lens is made of the plastic using the injection molding method because of its cost and weight. In this study, the mold core for F-Theta lens, which is consisting of two non-axisymmetric aspheric surfaces, was processed by fly-cutting method, and the form accuracy of the mold core was measured. The product of the F-Theta lens, which was fabricated by the injection molding method, was satisfied that can be applied to the actual specifications.
