摘要： A plastic optical element for focusing light to a target includes a first lens and a second lens. The first lens includes an incident surface, a projection surface opposite the incident surface, and a non-optical surface through which light does not pass and that includes a non-transfer portion. At least one light beam passes from the incident surface to the projection surface. The second lens includes an incident surface, a projection surface opposite the incident surface, and a non-optical surface through which light does not pass and that includes a non-transfer portion disposed opposite the non-optical surface of the first lens. At least one light beam passes from the incident surface to the projection surface. The non-transfer portions of the first lens and the second lens are portions on which no surface is transferred from a surface of a mold used to form the plastic optical element.
