    • A method for producing a wafer lens provided with a lens portion made of a photo-curable resin on one face of a substrate. The method includes a dispensing step, a curing step and a releasing step. In the dispensing step, a photo-curable resin material is dispensed on at least one of (i) a mold having a molding surface in a shape corresponding to an optical surface shape of the lens portion and (ii) the one face of the substrate. The photo-curable resin material has a viscosity of 10000 cP or more at 25° C. In the dispensing step, the photo-curable resin material is heated so that the viscosity of the photo-curable resin material becomes between 1000 cP and 10000 cP, and dispensed.
    • 一种晶片透镜的制造方法,其在基板的一个面上设置有由光固化树脂制成的透镜部。 该方法包括分配步骤,固化步骤和释放步骤。 在分配步骤中,光可固化树脂材料分配在(i)具有与透镜部分的光学表面形状相对应的形状的模制表面的模具中的至少一个和(ii)基板的一个面 。 光固化性树脂材料在25℃下的粘度为10000cP以上。在分注工序中,对光固化树脂材料进行加热,使得光固化树脂材料的粘度为1000cP〜10000cP 并分配。
