Effect of Injection Molding Conditions of Effective Surface Properties of F-theta Lens

초록

The effective surface of lens was studied for injection molding process and to enable mass production off-theta lens, which is the primary component of laser printers and laser scanning systems. Injection moldingis an optimal method if f-theta lens is frequently used for the mass production of plastic lenses as anaspherical lens that requires ultra-precision. A uniform injection molding system should be maintained toproduce high quality lenses. Additionally, to maintain these injection molding systems, various factors such aspressure, speed, temperature, mold and cooling should be considered. However, a lens with the opticalcharacteristics of an f-theta lens can be obtained. The effects of melting and cooling of plastic resin on theeffective surface of f-theta lenses and the numerous factors that affect the injection molding process werestudied.
