Abstract

PURPOSE:To manufacture a Fresnel lens simply and continuously by cooling and fixing the engraved groove after forming the engraved groove on soft gel surface by the mold and also polymerizing and hardening total soft gel by irradiating light or radioactive ray. CONSTITUTION:Soft gel 1 is passed between the mold 2 having the grooves engraved for Fresnel lens and the sample material platen 3, and immediately after passing it is cooled and the engraved grooves on soft gel 1 surface are fixed and also totality is polymerized and hardened by irradiating light or ionizable radioactive ray on soft gel 1. By this, the Fresnel lens can be manufactured simply and continuously.
