    Abstract: A lens, such as a lens for use in a wafer-level camera, is made by forming a polymeric material with at least one master to form a pre-final lens. The pre-final lens forms a majority of a final volume of the lens. The pre-final lens is allowed to harden, during which it may sag or shrink. An aliquot of polymeric material is added to the lens and formed with the same master with a spacer, or with a second master, to form a first surface layer that provides correction between the pre-final lens shape and a final desired lens shape. In an embodiment, the surface layer has similar or identical index of refraction to the pre-final lens. In an embodiment the lens is formed on a substrate. In an embodiment, a send master, or master pair, are used to form a lens having upper and lower curvature, with a second aliquot of polymeric material forming a second surface layer on a surface of the lens opposite to the first surface layer.

    Abstract translation: 通过用至少一个母版形成聚合物材料来形成透镜，例如用于晶片级相机的透镜，以形成预最终透镜。 预镜片形成镜片最终体积的大部分。 允许预最终镜片硬化，在此期间它可能会下垂或收缩。 将聚合物材料的等分试样添加到透镜中并用与间隔件相同的母版或与第二母版一起形成第一表面层，该第一表面层在预最终透镜形状和最终期望的透镜形状之间提供校正。 在一个实施例中，表面层具有与预最终透镜相似或相同的折射率。 在一个实施例中，透镜形成在基板上。 在一个实施例中，使用发送主机或主机对来形成具有上曲率和下曲率的透镜，第二等分的聚合材料在透镜的与第一表面层相对的表面上形成第二表面层。
