DIE FOR MOLDING FREE-FORM SURFACE OPTICAL ELEMENT, FREE-FORM SURFACE OPTICAL ELEMENT MOLDED BY USING SUCH DIE, AND FREE-FORM SURFACE MIRROR |
摘要 |
The present invention provides an injection mold for forming free-form surface optical element that is possible to produce with high accuracy at low cost a free-form surface optical element that has a stable relation between the free-form surface and the mounting reference surface and is easy to adjust when mounting. The mold comprises a fixed mold and a movable mold for forming a free-form surface (effective area 21) and a rear surface opposite to the free-form surface. The fixed mold and the movable mold are divided by a parting line PL along the peripheral end surface of the free-form surface optical element 14. A mold surface for molding the free-form surface (effective area 21) and a mold surface for molding axial-direction mounting reference surfaces 28a-28c for mounting the free-form surface optical element in a direction substantially perpendicular to the free-form surface are positioned in the mold on the same side with respect to the parting line PL.
