There are different requirements on mold plastic optics. Some of them require high index of light transmittance, while some of them require special refraction, deflection or reflection. According to the requirements, high gloss polishing, mirror finish EDM, high speed machining are employed in the manufacture of optics mold. The common resins for molding plastic optics are PMMA and PC. Accuplas has rich experience at building high precision mold for plastic optics, and developing the molding process.
