Molding Plano-Convex Lenses Using a through-Hole WC/Co Plate as the Mold

This study aims to fabricate the plano-convex lens by glass molding process using a through-hole WC/Co plate as the mold. The effects of temperature, applied loadand arc chamfer on the surface morphology, curvature, and peak height of plano-convex lenses were investigated. The through-hole mold with arc chamfer favors stress release and avoids cracks and surface mark. A higher temperature favors glass material flowing outwards rather than downwards, which results in the molded lens with a smaller curvature and bigger size.
